Output Voltage Programming By External Voltage; Current Programming By Pmbus (Optional) - Tdk-Lambda Rfe1600 Serie Bedienungsanleitung

3.2.6

Output Voltage Programming by External Voltage

Output Voltage of RFE1600 Series can be programmed by external voltage source between approximately
80%-120% for 24V, 32V, 48V and 80%-110% for 12V of nominal output voltage
(For Output voltage limits see Graph enclosed)
3.2.7

Current Programming by PMBus (Optional)

Over Current Protection (OCP) can be programmed by PMBUS with a range of 50% ~ 110% of Nominal Output Current.
If PMBus is used for current programming, the Reference voltage will not be fixed to 5V but variable.
