SPECIFICATION
INPUT SPECIFICATION
Input Range: Wide 2:1 Input DC Range 36-72Vdc
or 18-36Vdc.
Input Voltage: Nominal 48Vdc or 24Vdc.
Input Current: Typical 2.35A full load and 0.1A no-load
@ 48Vdc nominal input.
Typical 4.14A full load and 0.05A no-load
@ 48Vdc nominal input.
Input Fuse: Use external fuse.
Soft-Start: Installed.
Inrush Current: Peak 2.38A @ 48Vdc & 4.3A @ 24Vdc.
Input Filter: Pi-Network for EMI suppression.
Under-Voltage Protection (UVP): Lock-out activated at
34-35.5Vdc input @48Vdc nominal input.
17.5-17.8Vdc input @24Vdc nominal input.
Input OVP: 74-76Vdc @ 48Vdc nominal input.
37-38Vdc @24Vdc nominal input.
Input Reflected Ripple Current: 8.0mA pk-pk @48 Vdc.
Isolation Voltage: 1,500Vdc input-output.
Remote On/Off: TTL/CMOS-Compatible input control.
Positive Logic version for Standard set up:
ON(Enable)=Open(or 2.5-5.0Vdc above-Vin)
OFF(Disable)=Short(or 0-0.8Vdc above-Vin)
Negative Logic version option available by adding a
“N” suffix to the end of Model #.
Remark: Voltage refer to –Input (-Vin).
OUTPUT SPECIFICATION
Output Voltage: See Ratings Chart.
Output Current: See Ratings Chart.
Output Wattage: 48-110W typical continuous.
Line Regulation: 0.1% typical.
Load Regulation: Various with output voltage.
±0.5% typical.
Noise & Ripple: 1% rms typical.
OVP: Built-in (latch).
Adjustability: Factory set. Maybe externally trimmed with
fixed resistor or trim pot.
Overload Protection (OLP):
Fully protected against output overload and short circuit.
OLP set at about 125-150% rating output wattage.
Consult the factory for OLP setting.
GENERAL SPECIFICATION
Efficiency: 88-90% typical, various with input & output.
Switching Frequency: Fixed frequency 330K Hz.
Circuit Topology: 330K Hz. Forward Circuit.
Transient Response: Peak transient 150mV and recovers
within 2mS after 25% load-change.
Safety Standard: IEC60950 Class II.
Case: Aluminum base plate with metal standoffs.
Power Density: 29-66 Watts / Cubic inch typical.
Industrial Grade.
Operating Temperature: -40 to +100°C (base plate)
Power derating details please refer to the Derating Chart.
Storage Temperature: -55 to +125 °C.
Temperature Coefficient: ± 0.02%/°C.
Humidity: Up to 95% RH, Non-Condensing.
Cooling: At least 100LFM moving air is recommended for full
load > +25°C room temperature in a confined area.
Air flow vs. Power derating details, please refer to the
Derating Chart.
NOTE: (1) All measurements are at nominal input, full load, and +25°C unless otherwise spec.
(2) Line Regulation measured from High to Low Lines at full load.
(3) Load Regulation measured from Full-Load (F-L) to Half-Load(H-L)at nominal input.
(4) Correct fuse size by calculating the max. DC current drain at low Line input & adding 20-25% for desired fuse size.
