General Information
Reliability
The failure rate (λ) and mean time between failures
(MTBF= 1/λ) is calculated at max output power and an
operating ambient temperature (TA) of +25°C. Flex uses
Telcordia SR-332 Issue 2 Method 1 to calculate the mean
steady-state failure rate and standard deviation (σ).
Telcordia SR-332 Issue 2 also provides techniques to
estimate the upper confidence levels of failure rates based
on the mean and standard deviation.
Mean steady-state failure rate, λ
Std. deviation, σ
202.797 nFailures/h
119.564nFailures/h
MTBF (mean value) for the PKE522X series = 4.93 Mh.
MTBF at 90% confidence level = 2.75 Mh
The products are compatible with the relevant clauses and
requirements of the RoHS directive 2011/65/EU and have a
maximum concentration value of 0.1% by weight in
homogeneous materials for lead, mercury, hexavalent
chromium, PBB and PBDE and of 0.01% by weight in
homogeneous materials for cadmium.
Exemptions in the RoHS directive utilized in Flex products
are found in the Statement of Compliance document.
Flex fulfills and will continuously fulfill all its obligations
under regulation (EC) No 1907/2006 concerning the
registration, evaluation, authorization and restriction of
chemicals (REACH) as they enter into force and is through
product materials declarations preparing for the obligations
to communicate information on substances in the products.
Quality Statement
The products are designed and manufactured in an
industrial environment where quality systems and methods
like ISO 9000, Six Sigma, and SPC are intensively in use to
boost the continuous improvements strategy. Infant
mortality or early failures in the products are screened out
and they are subjected to an ATE-based final test.
Conservative design rules, design reviews and product
qualifications, plus the high competence of an engaged
work force, contribute to the high quality of the products.
Warranty
Warranty period and conditions are defined in Flex General
Terms and Conditions of Sale.
Limitation of Liability
Flex does not make any other warranties, expressed or
implied including any warranty of merchantability or fitness
for a particular purpose (including, but not limited to, use in
life support applications, where malfunctions of product can
cause injury to a person’s health or life).

Safety Specification
General information
Flex Power DC/DC converters and DC/DC regulators are
designed in accordance with the safety standards
IEC 62368-1, EN 62368-1 and UL 62368-1 Audio/video,
information and communication technology equipment Part 1: Safety requirements
IEC/EN/UL 62368-1 contains requirements to prevent injury
or damage due to the following hazards:
•
•
•
•
•
•
Electrical shock
Electrically-caused fire
Injury caused by hazardous substances
Mechanically-caused injury
Skin burn
Radiation-caused injury
On-board DC/DC converters, Power interface modules and
DC/DC regulators are defined as component power
supplies. As components they cannot fully comply with the
provisions of any safety requirements without “conditions of
acceptability”. Clearance between conductors and between
conductive parts of the component power supply and
conductors on the board in the final product must meet the
applicable safety requirements. Certain conditions of
acceptability apply for component power supplies with
limited stand-off (see Mechanical Information for further
information). It is the responsibility of the installer to ensure
that the final product housing these components complies
with the requirements of all applicable safety standards and
regulations for the final product.
Component power supplies for general use shall comply
with the requirements in IEC/EN/UL 62368-1. Product
related standards, e.g. IEEE 802.3af Power over Ethernet,
and ETS-300132-2 Power interface at the input to telecom
equipment, operated by direct current (dc) are based on
IEC/EN/UL 62368-1 with regards to safety.
Flex Power DC/DC converters, Power interface modules
and DC/DC regulators are UL 62368-1 recognized and
certified in accordance with EN 62368-1. The flammability
rating for all construction parts of the products meet
requirements for V-0 class material according to
IEC 60695-11-10, Fire hazard testing, test flames – 50 W
horizontal and vertical flame test methods.
Isolated DC/DC converters & Power interface modules
The product may provide basic or functional insulation
between input and output according to IEC/EN/UL 62368-1
(see Safety Certificate), different conditions shall be met if
the output of a basic or a functional insulated product shall
be considered as ES1 energy source.
For basic insulated products (see Safety Certificate) the
output is considered as ES1 energy source if one of the

following conditions is met:
• The input source provides supplementary or double or
reinforced insulation from the AC mains according to
IEC/EN/UL 62368-1.
• The input source provides functional or basic insulation
from the AC mains and the product’s output is reliably
connected to protective earth according to
IEC/EN/UL 62368-1.
For functional insulated products (see Safety Certificate)
the output is considered as ES1 energy source if one of the
following conditions is met:
• The input source provides double or reinforced
insulation from the AC mains according to
IEC/EN/UL 62368-1.
• The input source provides basic or supplementary
insulation from the AC mains and the product’s output is
reliably connected to protective earth according to
IEC/EN/UL 62368-1.
• The input source is reliably connected to protective
earth and provides basic or supplementary insulation
according to IEC/EN/UL 62368-1 and the maximum
input source voltage is 60 Vdc.
Galvanic isolation between input and output is verified in an
electric strength test and the isolation voltage (Viso) meets
the voltage strength requirement for basic insulation
according to IEC/EN/UL 62368-1.
It is recommended to use a slow blow fuse at the input of
each DC/DC converter. If an input filter is used in the circuit
the fuse should be placed in front of the input filter. In the
rare event of a component problem that imposes a short
circuit on the input source, this fuse will provide the
following functions:
• Isolate the fault from the input power source so as not
to affect the operation of other parts of the system
• Protect the distribution wiring from excessive current
and power loss thus preventing hazardous overheating

Stress in excess of Absolute Maximum Ratings may cause permanent damage. Absolute Maximum Ratings, sometimes referred to as no destruction limits,
are normally tested with one parameter at a time exceeding the limits in the Electrical Specification. If exposed to stress above these limits, function and
performance may degrade in an unspecified manner.

Operating Information
Input Voltage
The input voltage range is 18 to 75 Vdc.
At input voltages exceeding 75 V, the power loss will be higher
than at normal input voltage and TP1 must be limited to
absolute max +115°C. The absolute maximum continuous
input voltage is 75 Vdc.
Short duration transient disturbances can occur on the DC
distribution and input of the product when a short circuit fault
occurs on the equipment side of a protective device (fuse or
circuit breaker). The voltage level, duration and energy of the
disturbance are dependant on the particular DC distribution
network characteristics and can be sufficient to damage the
product unless measures are taken to suppress or absorb this
energy. The transient voltage can be limited by capacitors and
other energy absorbing devices like zener diodes connected
across the positive and negative input conductors at a number
of strategic points in the distribution network. The end-user
must secure that the transient voltage will not exceed the
value stated in the Absolute maximum ratings. ETSI TR
100 283 examines the parameters of DC distribution networks
and provides guidelines for controlling the transient and
reduce its harmful effect.
{Turn-off Input Voltage}
The products monitor the input voltage and will turn on and
turn off at predetermined levels.
The minimum hysteresis between turn on and turn off input
voltage is about 1 V.
Remote Control (RC)
The products are fitted with a
remote control function referenced
to the primary negative input
connection -In, with negative and
positive logic options available.
The RC function allows the product
to be turned on/off by an external
device like a semiconductor or
mechanical switch. The RC pin has
an internal pull up resistor to +In.
The external device must provide a minimum required sink
current to guarantee a voltage not higher than maximum
voltage on the RC pin (see Electrical characteristics table).
When the RC pin is left open, the voltage generated on the
RC pin is 3 – 6 V.
The standard product is provided with “negative logic” RC and
will be on until the RC pin is connected to the -In. To turn off
the product the RC pin should be left open, or connected to a
voltage higher than 2 V referenced to -In. In situations where it
is desired to have the product to power up automatically
without the need for control signals or a switch, the RC pin can
be wired directly to -In.

The second option is “positive logic” remote control, which can
be ordered by adding the suffix “P” to the end of the part
number. When the RC pin is left open, the product starts up
automatically when the input voltage is applied. Turn off is
achieved by connecting the RC pin to the -In. The product will
restart automatically when this connection is opened.
See Design Note 021 for detailed information.
Input and Output Impedance
The impedance of both the input source and the load will
interact with the impedance of the product. It is important that
the input source has low characteristic impedance. The
products are designed for stable operation without external
capacitors connected to the input or output. The performance
in some applications can be enhanced by addition of external
capacitance as described under External Decoupling
Capacitors.
If the input voltage source contains significant inductance, the
addition of a 22 µF capacitor across the input of the product
will ensure stable operation. The capacitor is not required
when powering the product from an input source with an
inductance below 10 µH. The minimum required capacitance
value depends on the output power and the input voltage. The
higher output power the higher input capacitance is needed.
Approximately doubled capacitance value is required for a 24
V input voltage source compared to a 48 V input voltage
source.
External Decoupling Capacitors
When powering loads with significant dynamic current
requirements, the voltage regulation at the point of load can
be improved by addition of decoupling capacitors at the load.
The most effective technique is to locate low ESR ceramic and
electrolytic capacitors as close to the load as possible, using
several parallel capacitors to lower the effective ESR. The
ceramic capacitors will handle high-frequency dynamic load
changes while the electrolytic capacitors are used to handle
low frequency dynamic load changes. It is equally important to
use low resistance and low inductance PWB layouts and
cabling.
External decoupling capacitors will become part of the
product’s control loop. The control loop is optimized for a wide
range of external capacitance and the maximum
recommended value that could be used without any additional
analysis is found in the Electrical specification.
The ESR of the capacitors is a very important parameter.
Stable operation is guaranteed with a verified ESR value of >5
mΩ across the output connections.

representative.

Over Temperature Protection (OTP)
The products are protected from thermal overload by an
internal over temperature shutdown circuit.
When TP1 as defined in thermal consideration section exceeds
115°C the product will shut down. The product will make
continuous attempts to start up (non-latching mode) and
resume normal operation automatically when the temperature
has dropped >5°C below the temperature threshold.
Over Voltage Protection (OVP)
The products have output over voltage protection that will shut
down the product in over voltage conditions. The product will
make continuous attempts to start up (non-latching mode) and
resume normal operation automatically after removal of the
over voltage condition.
Over Current Protection (OCP)
The products include current limiting circuitry for protection at
continuous overload. The output voltage will decrease towards
zero for output currents in excess of max output current (max
IO). The product will resume normal operation after removal of
the overload. The load distribution should be designed for the
maximum output short circuit current specified.

Thermal Consideration
General
The products are designed to operate in different thermal
environments and sufficient cooling must be provided to
ensure reliable operation.
For products mounted on a PWB without a heat sink attached,
cooling is achieved mainly by conduction, from the pins to the
host board, and convection, which is dependant on the airflow
across the product. Increased airflow enhances the cooling of
the product. The Output Current Derating graph found in the
Output section for each model provides the available output
current vs. ambient air temperature and air velocity at
VI = 48 V.
The product is tested on a 107 x 45 mm, 70 µm (2 oz),
1-layer test board in a wind box with 370 x 220 mm.
For products with base plate used in a sealed box application.
Cooling is achieved mainly by airflowing. The Output Current
Derating graphs are found in the Output section for each
model. The product is tested in a sealed box test set up with
ambient temperatures 25°C.

Soldering Information - Hole Mounting
The hole mounted product is intended for plated through hole
mounting by wave or manual soldering. The pin temperature is
specified to maximum to 270°C for maximum 10 seconds.
A maximum preheat rate of 4°C/s and maximum preheat
temperature of 150°C is suggested. When soldering by hand,
care should be taken to avoid direct contact between the hot
soldering iron tip and the pins for more than a few seconds in
order to prevent overheating.
A no-clean flux is recommended to avoid entrapment of
cleaning fluids in cavities inside the product or between the
product and the host board. The cleaning residues may affect
long time reliability and isolation voltage.
Delivery Package Information
