Product Introduction
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 port 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 port of the battery pack switch, the closed bus, and the control bus are correct, and observe whether the voltmeter is turned on. anti.
Main features
System Features
High reliability:
Adopt modular design of switching power supply, N+1 hot backup.
The charging module can be hot-swapped and unplugged, the average
maintenance time is greatly reduced.
The power bus and the control bus can be directly powered by the
charging module alone, and can be thermally backed up by the
voltage reduction device.
The hardware low-difference independent current sharing technology,
the maximum unbalance of the output current between the modules is
better than 5%.
Reliable lightning protection and electrical insulation measures,
the insulation monitoring device can monitor the insulation of the
system in real time to ensure system and personal safety.
The system design adopts IEC, UL and other international standards,
and the reliability and safety are fully guaranteed.
