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.

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.
Due to requests in market and advances in technology, specifications subject-35
to -change without notice.
