Emerson R48-2000A3 Eight special fault protection

1Emerson R48-2000A3Input too/Under voltage protection

When the input voltage is less than80Vac±5VacOr greater than305Vac±5VacThe protection indicator light (Huang Deng) is bright, and the module will stop working and no output. The input voltage is restored to97.5295VacWithin the scope, the rectifier module automatically restored to normal operation.

When the overvoltage protection event occurs, the module will report to the monitoring module.

2Emerson R48-2000A3Output overvoltage protection

The rectifier module has output overvoltage hardware protection and output overvoltage software protection, and the hardware overvoltage protection point is59.5V±0.5VAfter the hardware overvoltage protection, manual intervention can be started. The software protection point can be set by monitoring module, and the setting range is as follows5659VIt requires higher output voltage0.5VAbove, factory default value is59V

Software overvoltage protection mode can be selected by monitoring module:

1One time overvoltage locking mode

When the rectifier module generates software overvoltage, the rectifier module is shut down and maintained, and it needs manual intervention to recover;

2Two overvoltage lock mode

The rectifier module is protected and shut down5Reboot in seconds, if in the set time (default is5Second times over voltage can be set up by monitoring module setting, the rectifier module is shut down and maintained, and manual intervention is needed to start the system. Manual intervention method: through the monitoring module reset rectifier module, can also be removed from the power supply system from the rectifier module to reset.

When the overvoltage fault occurs, the module reports the fault signal to the monitoring module for corresponding processing.
