Table 4 – Remote Connector Plug Pin Assignment for External Variable Voltage Sources
A variable external DC voltage source of 0 – 5 V is fed into the analog remote control
terminal to adjust the output voltage level of both Main and Auxiliary output.
WARNING: Do not input higher than 5 V, otherwise the overvoltage protection
(OVP) will be triggered.
1.
Make sure the load is disconnected and the power supply is OFF.
2.
Connect pin 2 to positive polarity of first external voltage source and pin 4 to
negative polarity of first external voltage source.
3.
Connect pin 3 to positive polarity of second external voltage source and pin
4 to negative polarity of second external voltage source.
4.
Turn the remote control ON/OFF switch to ON position.
