DC power supply correct use of the method?
The fifth step, set the overvoltage protection OVP. Overvoltage setting means that the upper limit voltage is further limited within the adjustable voltage range of the power supply itself to prevent the power supply from being excessively high when the inverter is operated. In general, overvoltage can be set to the usual maximum operating voltage of 120% level. Overvoltage settings need to use a word screwdriver, adjust the panel concave potentiometer, which is a way to prevent the malfunction of the design. Set the OVP voltage, the first power supply voltage adjustment to the target over-voltage point, and then slowly adjust the OVP potentiometer, so that power protection happens to action, this time OVP will be set to complete. Then, turn off the power, reduce the operating voltage, will be able to work properly. Set the operating voltage Refer to the third step above. Different power settings, OVP different ways.
The sixth step, the communication interface parameter setting and the remote control operation establishment. For local control applications (panel operation) to turn off remote operation. The communication interface should be set according to the communication requirements, and the local application will not need to be set.
The third step, set the output voltage. By adjusting the voltage setting knob, the digital voltmeter shows the target voltage, complete the voltage setting. For adjustable current limiting power supply, there are two sets of adjustment system to adjust the voltage and current. Adjustment to be clear, the general adjustment of the voltage potentiometer "VOLTAGE" words, adjust the current potentiometer "CURRENT" words. Many of the entry-level products use low-cost coarse / fine twist knob settings, encounter double adjustment knob, we first fine knob knob to the middle position, and then through the coarse knob to set the approximate voltage, and then fine knob Precise correction.
Step 4, set the current. Press the "Power" button on the power panel, then the ammeter will show the current value, adjust the current knob, so that the current value reaches a predetermined level. The general current limit can be set at 120% of the maximum current used. Some power supply without limiting the special adjustment button, the user needs to follow the instructions required short-circuit output, and then according to the short-circuit current limit with the current limit set current limit. Simple adjustable power supply without current setting function, there is no corresponding knob.
DC power supply is relatively simple, the main operation is the corresponding power settings.
The first step, power connection. Connect the regulated power supply to the electricity.
The second step, turn on the power. In the case of no load, press the power switch (power), and then turn on the power supply DC output switch (output), so that the normal power output work (some simple adjustable power supply only the total power switch, no independent DC Output switch). At this point, the power supply digital indicator shows the current operating voltage and output current.
