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.

Efficiency: 82% minimum (Measuring at 230V and full load).

:

Turn On Delay 1 second maximum at 120 VAC.

Hold Up Time: 20 mS min. at 80% of full load.

Adjustability: Output user adjustable ±5% minimum.

Remote Sense: Designated “RS+” and “RS-” on the CN3.

Remote On-Off:

(Not available for current sharing models)

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.

Power Good: Designated as “PG” on the CN3 will go high 100-

500 mS after regulation and goes low 1mS before loss of regulation.

Current Sharing: Designated as “CSH” on the CN3, optional

single wired for forced current sharing function and parallel up to 4

units within 10% accuracy at full load.

Current Monitor: Designated as “CMN” on the CN3 for current

sense for a 0.5V to 3 VDC to represent 0% to 100% output current.

Margin: Designated as “MGN” on the CN3 providing 50% of output

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 Circuit (primary):

(Input voltage protection must be disabled when AC Fail is enable.)

Two protected fuse inserted, shall be

blown only by an internal power fault.

Input Voltage Protection: Power shut down under 80 ±5 Vac,

and recovered over 86 Vac.

Over-Power Protection:

(Disabled unless AC Fail is requested)

C.C. mode 110-140% and auto-recovery.

Over-Voltage Protection: Latching down will occur when output

voltage exceed 130% and recycle AC input to reset.

Short Circuit Protection: Trip without damage and auto-recovery.

Over Temperature Protection: 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: -20 to 85°C.

Operating Humidity: 5% to 90% RH, Non-condensing.

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

C22.2 No. 60950-1-03/ 601.1-M90, TUV EN60950-1/ 60601-1, CE

Mark (LVD) EN61204-3/ 60601-1-2/ 61000-3-2,3 & IEC61000-4

Series Regulations and CB.
