switch first before turning this button on; conversely, turn this button off before switching off the air switch in the back.
For the models without air switch, this button turns the power on and off.
1) Constant Voltage (CV) Operations
e) Adjust current knobs (knobs 3 or 4) to slightly above zero so that CV indicator light is on, and set voltage
(knobs 12 and 13) to the desired output voltage.
f) Connect the external load to the output terminals. Make sure both "+" and "-" terminals are connected correctly.
For output more than 10A, you must use the rear terminals.
g) Turn the current knob to maximum to ensure that the power supply stays in CV mode. If it’s necessary to limit
the current while operating in the CV mode, follow 3-4 first to set the current limit.
h) Once finished, turn the current down to < 1A, disconnect the load, and then turn off the power supply.
2) Constant Current Operation
e) Adjust current knobs (knobs 3 or 4) to slightly above zero so that CV indicator light is on, adjust voltage
control (knob 12 & 13) to set voltage to the desired voltage limit (this is the upper voltage limit and typically
above the operating voltage). If charging a battery, set the voltage to the normal charging voltage recommended
by the battery manufacturer.
f) Connect the external load to the output terminals. Make sure both "+" and "-" terminals are connected correctly
in terms of polarity. For output more than 10A, you must use the rear terminals.
g) Turn the current knobs slowly up until you reach the desired current level. Make sure CC light is red.
