1000 ~ 3000W 1U Distributed Power System

RCP-1U Rack System

Function Manual

1. Remote ON/OFF Control

The PSU can be turned ON/OFF together or separately by using the "Remote ON-OFF" function.

2.1 Remote Sense

(1)Output voltage can be trimmed between 90~110% of its rated value by the following method.

(2)+S & +V, -S & -V also need to be connected on CN500.

The remote sense compensates voltage drop on the load wiring up to 0.5V.

2.2 Local Sense

Notice : The +S,-S, on CN500 have to be connected to the +V,-V terminals locally in order to get the correct output voltage if the remote sensing is not used.
