Notes from page 1

1. Operating period at peak output current is 4 sec, max duty cycle <35% & < rated output power

2. At 115 / 230VAC, Ta = 25°C, nominal output voltage, rated output power

3. Ripple & noise is measured at 20MHz using 300mm twisted pair of load wires terminated with 0.1μF lm cap & 47μF electrolytic cap

4. Constant current (CC) limit for >105% of peak output current. CC limit with auto recovery within 4 sec, unit will shutdown at >4sec

5. Output will shutdown, manual reset by mains cycle off/on or CNT on/off

6. Refer to instruction manual

*Signal connectors are found on the topside of the unit.

Signal Connector Pin Assignment

PIN Function Detail

1 CB

For parallel operation cut the link between pins 1 & 2 for droop mode current share

2 CB-COM

3 N/C

No Connection

4 N/C

5 CNT+

Remote ON/OFF control, when CNT+ is pulled to TTL low the power supply turns ON, otherwise it turns OFF

6 CNT-

7 PV

Programming voltage range 5 - 6V presets the output to 24 - 28V

8 COMM

DRF120 example* Terminal Explanation

Connection

1 +V: +Output terminal

2 –V: –Output terminal

3 V.ADJ: Output voltage adjust trimmer

The output voltage rises when a trimmer is turned clockwise

4 L: AC Input terminal. Live line (fuse in line)

5 N: AC Input terminal. Neutral line

6 : Protective Earth

Connect to safety ground of apparatus or equipment

7 DC OK:

Green LED lights when output voltage is > 80% of rated output voltage

8 PEAK:

Red LED lights when unit is in peak power mode

9 DC OK: Relay contact

10 DC OK: Relay contact
