Operation Instructions
1.
Notice
(1)
AC Input
AC Input should be 110V±1% and 60Hz
(2)
Heat Radiator
The heat sink radiator is located at the back of the power supply. Enough space
should be left for heat dispensing. Do not use the power supply where the ambient
temperature exceeds 40ºC
2.
Operations
•
Plug the AC power input
•
Turn on the power switch “ON”
•
Adjust the VOLTAGE(master and slave) to the desired value
•
Connect the external load to the “+” and “-” terminals.
•
When the power supply is used with an unstable load, either the output terminal
“+” or “-” should be reliably connected to the GND terminal(depending the output
is used in positive or negative mode) to decrease the ripple on the output voltage.
•
Setting of Constant Current
First make sure the maximum load current; then use a short-circuit wire to
directly short the output terminal (+) to (-), and adjust the current control knob
clockwise to the desired value; finally take off the short-circuit wire; adjust the
Voltage knob to the desired value.
Independent mode
Set both of the mode switches at the up position.
If used in constant voltage mode, turn both of the current knobs clockwise to the
maximum. Adjust the voltage knobs to the desired values.
If used in constant current mode, turn the voltage knobs clockwise to the maximum.
Adjust the current knobs to the desired values.
Serial mode
Set the left mode switch to down and right mode switch to up positions. Turn the
current knobs clockwise to the maximum, adjust the master channel (right) voltage
