Remote Sense Compensation Setup
Before use Remote Sense compensation function, take off short connect terminal on the Remote Sense compensation
terminal, connect load voltage positive terminal to compensation terminal S+ and load voltage negative terminal connect
to compensation terminal S-. And then enable power output to turn on Remote Sense compensation function. That is,
the output voltage of the DC power supply is the voltage of the load terminal.
Notice: Remote Sense compensation voltage should less than 0.6V.
CV/CC Operating Mode of Power Supply
Power supply can automatic transfer constant voltage/current function. Power supply can ongoing switch the constant
voltage/current function dependends on load fluctuation.
If the current load is on the constant voltage mode, power supply provide a controlled output and voltage. As the load
resistance value decreases, the output voltage remains constant until the output current increases to greater than the
preset current value, which it will convert operating mode. If the power supply turn into constant current output, the
output voltage will decrease proportionally according to resistance value of the load. When the current value less than
the set value, power supply will back to the constant voltage mode.
Troubleshooting
Power supply is no output
1． Check the set value of voltage and current is zero or not. If it is, reset the voltage and crrent value.
2． OUTPUT indicator light is light on or not. If it is, push OUTPUT key to enable the output function.
3． Check OVP，OCP，OTP function is activated or not. If it is, reset the value of OVP, OCP and wait the power supply
remain stable to turn the output function.
4． If Remote Sense compensation function has been enabled, check the line loss of output cable is excced thelimit
value or not. If it is, replace the output cable or decrease the output current, and then try to enable the power
supply again.
The keyboard is not work
Check Lock indicator light is light on or not. If it is, please refer to Lock section to reset again.
