III. Direction For Use
3-1Precautions
(1) AC input: AC input should be 220v±10% 50Hz (on the back of the case will be mark if it is for 110v±10% 60Hz).
(2) Isolation: DO NOT use it in conditions of temperature above 40℃, the heat abstraction fan is on the back of the instrument, there
should be enough room for heat abstraction.
There is a temperature switch in the double channel power supply of RXN series, when inside temperature is upper than 45℃, the fan
will revole automatically for heat abstraction. DO NOT use it in conditions of temperature above 40℃
3-2 Operating Method
(1) Link up to the power (AC220v±10%).
(2) Turn the power switch to ON, the indicator lights.
(3) Tune knob “VOLTAGE”to the voltage that needed.
(4) Connect the outer load to the output terminals of “+”, “-”.
(5) When used in places with high ripple factor, either “+”or “-”connector should be connected to GND connector tightly, so the ripple
voltage would decrease.
(6) Constant current tuning: Firstly tune the voltage to any value from 3~10V, with current tuning to 0 and anti-clockwise to the end, then
short circuit the positive electrode and negative electrode with the conductor, thirdly tune the current knob clockwise to the limitation
current the needed. Take off the short circuit lead, then tune the voltage to the value that needed.
(7) Attention: DO NOT start the power supply with load, nor the power supply and the load would get damaged. When the load is greater
than 20A, please use the terminals on the back.
IV Maintain
4-1 Replacing the fuse
If the fuse breaks, the power supply will stop operating, in this occasion, the cause of the break must be found out, and after
correction, use a same fuse to replace the broken one, the fuse box should not be open unless the problem happens.
4-2 Maintain
Once the power supply inside is burnt out, it must be repaired by professionals or sent to the dealer to send back to the factory for
repair. DO NOT repair it separately to ensure safety.
