1. Notice
(1)AC Input
AC Input should be 220V¡À 10%50Hz(if 110V¡À 10%60Hz it indicated on the rear case)
(2)Isolation
Do mot use the unit where ambient temperature is above 40o C, Radiator locates at the back of the unit, enough space should be remained for heat sinking. The temperature of radiator can up to 100o C, do not touch it after long time working.
(3)Overshoot Limiting of Output voltage
When turn on, the voltages between output terminals should not higher than the preset value. 2. Setting of Current Limiting
Make sure the maximum safe current of the outside load.
Use a shortcircuit wire to short the Current terminals(+)to(-).
Adjust the Current control knob kill the CC indicator on.
Adjust the Current knob to the desired ampere.
After setting the current value(overload protection), then do not change the Current Control knob.
Take off the shortcircuit wire, it is standby status now. 3. Operation
Switch Power" OFF" .
Be sure Power input voltage correct.
Turn the Power switch on.
Switch Power " ON" .
Adjust the " VOLTAGE" And" CURRENT" Control knobs to the desired values
Connect the outside load to the " +" Or " -" Terminals.
When the unit used in high requirement condition, either the output terminal sturdily, so as to decrease the output ripple voltage.
