MEAN WELL RKP-1UT-CMU1 [4/6] Rkp 1u rack system

MEAN WELL RKP-1UT-CMU1 [4/6] Rkp 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
The remote sense compensates voltage drop on the load wiring up to 0.5V.
2.2 Local Sense
Notice : The +S,-S 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.

Sense lines should be twisted in pairs
(1)Connecting an external DC source between PV(4,10,19) and -V(25) on CN500 that is shown in Fig. 3.1.
(2)Adjustment of output voltage is possible between 90~110%(Typ.) of the rated output which is shown in Fig. 3.2. Reducing output current is required when the
output voltage is trimmed up.
