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 Date 3/17/2023 Rev 28701-BMR802 E Z Rev. E March 2023 © Flex 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 Non - isolated DC/DC regulators The DC/DC regulator output is ES1 energy source if the input source meets the requirements for ES1 according to IEC/EN/UL 62368-1. Prepared (Subject resp) 1 (7) No. jidgezou George Zou Approved (Document resp) 4 PUBLIC PRODUCT SPECIFICATION 2/1301-BMR802Technical Specification Checked PUB-1M series Zou DC/DC Converters jidgezou George Isolated 1W Unregulated Single Output Date 3/17/2023 Rev March 2023 28701-BMR802 Rev.

PUB0505S1M Test set-up Layout recommendations The radiated EMI performance of the product will depend on the PWB layout and ground layer design. It is also important to consider the stand-off of the product. If a ground layer is used, it should be connected to the output of the product and to the equipment ground or chassis. A ground layer will increase the stray capacitance in the PWB and improve the high frequency EMC performance.

For example, the input voltage range 4.5 to 5.5 Vdc meets requirement of general industrial used for 5Vdc system. The input voltage should never exceed the absolute voltage of the converter, and the ambient temperature must be limited to absolute max +110°C. The output voltage related to input voltage. Take 5Vin and 5Vo product as an example, if input voltage above 5V, the output voltage will higher than 5V. Below 5V and the output voltage starts to track the input voltage. 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 dependent 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 do not have under voltage lock-out function. Please make sure the input voltage of each module is correct working range. 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 product are designed for stable operation without external capacitors. With a 10µF capacitors connected to the input could reduce the input noise cause by parasitic inductance. External Decoupling Capacitors When powering loads with significant dynamic current requirements, the voltage regulation at the 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 Date 3/31/2020 Rev 28701-BMR802 Rev. E C March 2023 © Flex 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 and minimum 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 >1 mΩ across the output connections. For further information please contact your local Flex Power Modules representative. Parallel Operation This product is not designed for paralleling without using external current sharing circuits. See Design Note 006 for detailed information. Over Current Protection (OCP) The products include current limiting circuitry for protection at continuous overload. The OCP works in a hiccup mode and will make continous attempts to start up and will resume normal operation automatically after removal of the over current condition. The load distribution should be designed for the specified maximum output short circuit current. PUBLIC PRODUCT SPECIFICATION Prepared (Subject resp) 3/1301-BMR802 Technical Specification PUB-1MGeorge seriesZou DC/DC Converters jidgezou Checked Isolated 1W Unregulated Single Output Date Rev 28701-BMR802 Rev.
