KEY FEATURES
Digital Power’s HDM500 Series are switching power supplies that produce
superior output wattages with natural convection. The series include enclosed,
open fame and U bracket format with output voltage options of 12V, 15V, 24V
and 48V. Featured with compact, low profile footprint, and best-in-class
performance, HDM500 Series are optimal for ITE and Medical Applications.
Designed with energy saving in mind, Digital Power’s HDM500 Series boasts not
only high operating efficiency up to 93%, but also high-power density with full
input range of 90-264Vac.
HDM500 operates over wide temperature range from -30°C to +70°C with
complete protections and certified to UL / IEC / EN 60601 3.1rd Edition & UL /
IEC / EN 60950 AM2 Safety Approvals.

NOTE
1.
Ripple & Noise are measured at 20MHz of bandwidth with ceramic 0.1uF & chemi-con KY 47uF
parallel capacitor.
A 30cm twisted pair of no.18 AWG copper wire is connected to a 47uF and 0.1uF capacitor of
proper polarity and voltage rating. The oscilloscope probe ground led should connect right to
the ground ring of the probe and be as short as possible. The oscilloscope bandwidth should be
at 20MHz and connected to AC ground.
2. Hold-up Time measured at 90% Vout.
3. Please check the derating curve for more details.
4. Main Vout >3% Load, 12V (Aux) / 0.3A., 12V (Aux) need 0.1A Minimum Load, Auxiliary voltage
output ground 10.2~13.3V
5. Strongly recommend to conduct this test with DC Voltage. If customer wishes to test with AC
Voltage, please disconnect all Y-Capacitors from Digital Power power supply.
6. Current Share Board (Optional):
(a.)The output voltage difference of each parallel single element should be less than 0.2V.
(b.)Output power at parallel operation = rated power per unit x number of unit x 90%
(c.)Connect in parallel no more than 2 units.
Please contact Digital Power for advice if more than

2 is needed.
(d.)Minimum Load Should be 15%.
7. CAUTION: Double pole, neutral fusing.
Disconnect mains before servicing.

FUNCTION DESCRIPITON of CN1 and CN3 (CN3 without C7 and C8 pin)
Pin No.
Function
C1
-5VSB
Description
This pin connects to the negative terminal(-V). Return for DC-OK and -RC signal output.
C2
+5VSB
Stand by voltage output ground 4.2~5.5V, referenced to pin C1(5VSB). The maximum load current is 1A with Fan, 0.4A without Fan..
C3
GND
This pin connects to the negative terminal(-V). Return for DC-OK and -RC signal output.
C4
DC OK
DC-OK Signal is a DC output, referenced to pin C3(DC-OK GND).
C5
-RC
This pin connects to the negative terminal(-V). Return for DC-OK and -RC signal output.
C6
+RC
Turns the output on and off by electrical or dry contact between pin C5 (-RC), Short: Power OFF, Open: Power ON. The
input voltage must be less than 1V in order to disable VOUT and greater than 3.3V (up to 5V) to enable it.
C7
-S
Negative sensing. The -S signal should be connected to the negative terminal of the load. The -S and +S leads should be
twisted in pair to minimize noise pick-up effect.
C8
+S
Positive sensing. The +S signal should be connected to the positive terminal of the load. The +S and -S leads should be twisted
in pair to minimize noise pick-up effect.
