DRF Series FAQ


1. Question: How does the parallel circuit operate on the DRF series?

Answer:

When the jumper between pins 1 & 2 on CN201 (CN17 on the 480W) is cut or removed, the power supply will operate in droop mode current share.

For DRF480:

Load Regulation (typ): 0.643 V (No load to Full load)

Droop rate (typ): 32 mV/A

For DRF240:

Load Regulation (typ): 0.658 V (No load to Full load)

Droop rate (typ): 64 mV/A

For DRF120:

Load Regulation (typ): 0.531 V (No load to Full load)

Droop rate (typ): 120 mV/A
