Aux Output 2 USB port: 3.0 (5VDC, 2A) 12. LCD Display panel showing: - 4 digit voltmeter, Ammeter, (CV) constant voltage mode, (CC) constant current mode, - Output Terminal on/off state - 2 digit Aux outputs Ammeter - Aux Output 1 & 2 voltage indication - USB remote control 13. USB remote control OPERATIONS Ground Connection Depending on the application, the power supply output terminals can be grounded in any one of the following grounding conditions: Negative ground black (-) negative terminal is shorted with green GND terminal. Positive ground red (+) positive terminal is shorted with green GND terminal. Floating ground green terminal is not shorted with any of the output terminals. Remarks: When operating this power supply as a floating ground, high impedance leakage can exist between the power supply circuitry and the chassis ground. Basic Mode of Operation This power supply is designed to operate as a constant voltage source or as a constant current source. Automatic crossover to either mode of operation occurs when the load condition changes as following: Constant Voltage (CV), Automatic crossover & Constant Current (CC) The power supply functions as a constant voltage source (CV) as long as the load current is less than the preset current limiting value. When the load current is equal to or greater than the preset current limiting value, the power supply will automatically cross over to the constant current mode, voltage will drop, (CC) will show on the LCD display panel and it will operate as a constant current source. When the load current drops below the preset current limiting value, the supply returns to constant voltage (CV) mode. Set the Output Voltage and Presetting Current Limiting Value (CC) Turning the voltage or current knob to set your desired values. Quick pushes on the knobs will move the decimal place for fast tuning. Turn the knob when the desired number column is flashing otherwise you need to repeat quick pushes again. One quick push on the current knob to see the preset current limiting value. Connection and Operation Procedure 1. After checking with the rating label plug in to AC mains. 2. Switch on the power supply and the LCD display should be on at the same time. 3. The (CV) icon should be shown on the display. 4. Turn the current volume knob (5) to maximum clockwise if you do not require lower Current limiting value, otherwise do the preset the (CC) limiting procedure. 5. Set your desired output voltage and then turn off the output terminal by push button (6). 6. Connect to your load positive to positive and negative to negative. 7. Turn on the output terminal again and check if display shows (CV). 8. If display shows (CC), either your preset current limiting value is too low or your load requires more voltage and current. You need to re-access the voltage and current requirement of your load and increase the voltage or current accordingly until (CV) appears. Check set voltage of Aux output a. Aux output 1 Press and hold the voltage knob for 3 seconds, the LCD display will indicate the set output voltage of Aux output 1 for around 3 seconds and then returns to main output voltage reading. b. Aux output 2 Press and hold the current knob for 3 seconds, the LCD display will indicate the set output voltage of Aux output 2 (5V) for around 3 seconds and then returns to main output voltage reading. Remark: This is not a voltmeter of Aux output. The LED display is ONLY indicate the set output voltage instead of the actual output voltage of Aux output. Tracking Output Over Voltage Protection (Fault Code F01) This is to protect the connected load in the event that the output voltage control circuit malfunctions, the maximum output voltage will not exceed 10% (min. 1.7V) of the adjusted voltage value at the time of the operation. Protection will be triggered and the output power will be cut off and ouP warning appears as below. To reset the warning, switch off the unit and remove all loading. Switch the unit back on again and it should resume normal operation. If this problem persists, please contact and consult with your agent. Over Current Protection (Fault Code F02) Normally the overload protection is sustained by the CC constant current mode. When the CC mode fails and goes undetected, it may cause serious damage to your test piece or load. The ocP is to minimize the extent of damage to your loads as power supplies do fail someday. Switch off your power supply as soon as you see this warning as shown below. To reset this warning, switch off the unit and remove all loading. Switch the unit back on again and double check with caution. If this problem cannot be fixed, please contact and consult with your agent. Over Temperature Protection (Fault Code F03) There is a thermo sensor inside the unit to monitor and to prevent the unit to gets too hot inside. At otP, there is no output and the following warning will appear on the LCD display. When you get this warning, switch off the unit and remove all loading. Check your load and output setting. Allow the unit to cool down for at least 30 minutes. Check if any of the ventilation is blocked, check enough clearance around power supply. Switch the unit back on again and it should resume normal operation. If this problem persists, please contact and consult with your agent. PC CONNECTION The NTP with USB can be remote control using Windows PC. Connecting the NTP to PC using provided USB cable as following connection diagram. The LCD display panel (12) will indicate once PC connected. It requests to install USB driver for NTP connection.
