Product overview
To debug the DC screen, turn on the AC power to test whether the AC dual power switching device is working properly and whether the voltage of the lower part of the dual power switching device is normal. After the AC part is tested normally, close the AC switch of the charging module in turn, observe whether the module starts normally, and measure the output voltage and polarity of the module. After the charging module starts normally and the output voltage and polarity are correct, turn on the battery pack switch and each bus switch, measure whether the voltage and polarity of the lower part of the battery pack switch, the closed bus, and the control bus are correct, and observe whether the voltmeter is turned on. anti.
