PFC:
Active power factor correction meet EN61000-3-2 class D.
Fan Drive:
12VDC/400mA is available to drive an external fan.
Transient Response:
Returns to within 1% in less than 2.5 mS for
a 50% load change and the peak transient does not excess 5%.
Overshoot:
Turn-on/off not exceed 5% over nominal voltage.

Designated as “RSW” on the CN3, requires a low
signal to inhibit output.
Power Supply On:
Green LED designated as “LED 1” on the PCB.
LED display:
Bi-color “LED1” emit green light on operating. Any
protection occurred or RSW applied low signal will emit orange.

voltage remote adjustment by applying 0.4 ~ 5V signal on “MGN”.
AC Fail (optional):
Designated as “ACF” on the CN3 to monitor the
input voltage, when input goes under 80 +/- 5VAC the signal will go
low (0V) and then go high (+5V) once reappears over 86 Vac.
(Input voltage protection must be disabled when AC Fail is enable.)

Over-Voltage Protection:
Latching down will occur when output
voltage exceed 130% and recycle AC input to reset.

Protected in the event of
excessive operating ambient 85°C, with automatic recovery.
Switching Frequency:
30 kHz fixed frequency.
Operating Temperature:
O to 70°C ambient, de-rating at 2.5%
per degree from 50°C to 70°C.
°
°
Storage Temperature:

Storage Humidity:
5% to 95% RH, Non-condensing.
Vibration:
Frequency 5 to 50 Hz, acceleration +/-7.35 M/(SxS) on
X,Y and Z Axis.
Emissions:
FCC Part 15, CISPR 22 class B, Conducted.
Safety Regulation:
Approved to UL60950-1/ 60601-1, CSA

cut off current); 4000 Vac between primary and secondary
windings; Primary to core 1500 VAC. All for 3 sec.
Grounding Test:
Apply 40 A from ground pin to the earthed
connection point. Maximum allowable resistance is 0.1ohm.
