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.
