3.1
Select Operation Voltage
EN
Click the adjusting selective button to “V” indicator turns on, click the adjusting knob, the volt meter display the set voltage and the adjustable position highlight as fig1, the highlight will shift from right to left when user clicks the knob continually. Then adjust the knob to set the highlight number.
For example: Set the output voltage is 24.15V. At first, click the knob, the rightmost position of the volt meter highlight, adjust the knob to set the highlight number to 5, then click the knob again the highlight will shift to left, adjust the knob to set the highlight number to 1, then set the highlight number to 4 and 2 in the same way, finally the output voltage is set to 24.15V.

4.1
Over Voltage Protection
MCU controls the tracking OVP, OVP value is relevant to the setting voltage, this function protect the appliance which connected to the power supply safely.
When OVP is triggered MCU shut down the output and the ammeter highlights
“ OUP ” . Press ON/OFF button to reset the OVP if the over voltage problem has been resolved.
4.2
Over Current Protection
MCU control the tracking OCP, OCP value is relevant to the setting current. This power supply can operate constant current mode, so if the C.C works normally the

”
, press ON/OFF button to reset the OCP if the over current problem has been detected.
4.3
Over temperature protection
The MCU monitor the temperature of the power supply, if the temperature is higher than the special value MCU shut down the output and ammeter highlights
“ OTP ” , press ON/OFF button to reset the OTP if the temperature lowered.

5.1
Series Connection
Several units can be connected in series in order to gain a higher total output voltage. To do so, the positive DC output of one unit is connected to the negative DC output of the next unit etc. The non-connected positive and negative of the last unit will be the positive and negative of the whole series output, and will have the high voltage output.
In view of safety and insulation, it is not allowed to connect an arbitrary number of units in series. The DC output of series system must not be raised higher than
500 V DC.
If units with different nominal current are connected in series, the minimum nominal current of the products is the maximum current of the system.
In a series connection, only negative DC output of one unit (the one with negative DC output in the series system) may be grounded.5.2 Parallel
Connection
Several units which are preferably same type, but at least identical nominal output voltage, can be connected in parallel in order to gain a higher total output voltage. It is recommended to adjust the output current to the maximum and the output voltage to identical value on every unit.
