3.2.3

ON/OFF Control by Enable

SIGNAL RETURN and ENABLE control are isolated from the output terminals and"-SENSE".
3.2.4

Output Voltage Programming by Built-in Potentiometer

Output Voltage of RFE1600 Series can be trimmed by potentiometer between approximately 80%-120% for
24V, 32V, 48V and 80%-110% for 12V of nominal output voltage (For Output voltage limits see Graph below).
3.2.5

Output Voltage Programming by PMBus (Optional)

Output Voltage of RFE1600 Series can be programmed by PMBus between approximately 80%-120% for 24V, 32V, 48V
and 80%-110% for 12V of nominal output.
