The charging module works in automatic switching mode by default. It
automatically switches to the low-voltage or high-voltage mode based on the
output port voltage, preset voltage, or battery voltage reported by the monitoring
module.
The automatic switching mode of the charging module can be set to any of the
following:
1. Automatic switching based on the module output port voltage (factory
default)
2. Automatic switching based on the preset voltage
3. Automatic switching based on the battery voltage reported by the monitoring
module
Manual switching is also supported. You can manually switch to the low-voltage
or high-voltage mode on the system monitoring module.
● Low-voltage mode: 200–506 V DC output
● High-voltage mode: 200–1000 V DC output
The charging module works in standard mode by default. You can set it to silent
mode on the system monitoring module based on the noise reduction
requirements.
● Silent mode: Multiple levels (55 dB max, 60 dB max, and 65 dB max) are
provided. In silent mode, the module output power is derated accordingly.
