Specifications

Fig. 2 above shows an example of 5 modules connected in

parallel to provide 50 Amps.

CAUTION! WHEN 2 OR MORE MODULES ARE

OPERATED IN PARALLEL, THE OUTPUT VOLTAGE

OF EACH MODULE SHOULD BE ADJUSTED TO THE

SAME EXACT VALUE WITH THE HELP OF POTEN-

TIOMETER VR1 ( See Figure 1 on page 4 )

• Adjust the output voltage of each module individu-

ally to the same output voltage.

• Feed AC input power to the 5 modules through a

common switch and breaker rated for 20A ( 4A

per module x 5 modules = 20A )

• Connect the positive and negative outputs of each

module in parallel.

• Connect a 200 ohm 5W power resistor across the

common output terminal to provide a static load.

( When units are operating in parallel, each unit

requires a minimum load for the current share

controller to work properly ).

• Inter-connect the share bus terminals marked

Jump 1 as shown in Fig. 2 above.

• Switch on AC power to the modules. Ensure that

green LED’s connected to LED1/LED2 are lighted.

• Switch on the DC load. All the green LEDs con-

nected to LED1/LED2 should remain lighted.
