In the lock state(Lock light is on) ˈ adjusting knob and ON/OFF button can’t change output state. 11 WATT Button Click, digital tube of ammeter highlights the current output power and light is on. Restore the current display automatically after display lasts 5 seconds. 12 ON/OFF button Click—output on or output off Press it for 5 seconds to set the output on at turn on the power supply. 13 Output Terminal Red—Output ‘+’/ Black—Output ‘-’ 14 AC Socket AC Input Socket 6 Function and Operation EN 3 Function and Operation 3.1 Select Operation Voltage 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. fig1 3.2 Set the output current Click the adjusting selective button to “A” indicator turns on, click the knob the Ammeter display the set current, the operation is same as setting voltage. 3.3 Turn on or turn off output When the output is turned off, the ammeter highlights “OFF” ˈ Click “ON/OFF ” button the output turned on. Then click the button again the output turned off. 7 Function and Operation EN 3.4 Set the output on at the AC power on Press “ ON/OFF ” button for 5 seconds, ammeter highlights “ dOn ” for 2 seconds, the output is set to on at the AC power on. To cancel this function, press “ ON/OFF ” button again for 5 seconds, ammeter highlights “ dOF ” for 2 seconds, The output is off at the AC power on. 3.5 Lock Click “ Lock ” button ˈ the “Lock” indicator turns on, ON/OFF button and adjusting knob are locked. To cancel the function please click the “ Lock ” button again and the lock light turns off. 3.6 Display the output power Click “ WATT ” button , the “Watt” indicator light turns on and ammeter highlights the output power for 3 seconds. 4 Protection 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 ˈ 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 8 Function and Operation EN OCP never be triggered; However if the C.C works abnormally the tracking OCP will protect the appliance which connected to the power supply safely. When OCP is triggered, MCU shut down the output and ammeter highlights “ OCP ” , 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 Application 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. ¾ 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. ¾ If units with different nominal current are connected in series, the minimum nominal current of the products is the maximum current of the system. ¾ 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.
