Rectifier module R48-3000E

4) PFC output over/Under voltage protection When the bus voltage inside the module exceeds the over/under voltage protection point, the module automatically shuts down for protection without output, and the protection indicator (yellow) on the panel of the module is on. When the PFC input overvoltage and undervoltage protection occurs, the module reports an alarm signal to the monitoring module for corresponding handling. 5) Fan Fault protection When the fan is faulty, the module generates a fan fault alarm, the fault indicator on the panel of the module blinks red, and the module shuts down without voltage output. After the fault is rectified, it automatically recovers to normal operation. When a fault event occurs, the module reports an alarm signal to the monitoring module for corresponding handling.

6) Short-circuit protection rectifier module adopts constant current protection mode, in the case of output short-circuit, the output current of the module remains constant, current ≤65A, effectively protect itself and external equipment; When the short circuit fault disappears, the module automatically recovers.

7) Output current imbalance When multiple rectifier modules are used in parallel in the system, the module with large current sharing error can automatically identify and light the protection indicator light (yellow light) on the panel of the module; If the output current of the module is seriously unbalanced, the module whose current equalization error is greater than 10A and the module has no output can automatically identify and light the fault indicator (red light) on the panel of the module. After the fault is rectified, it automatically recovers to normal operation. When a fault event occurs, the module reports an alarm signal to the monitoring module for corresponding handling.

8) Background communication interruption When the communication is interrupted, the protection indicator (yellow) of the module panel blinks. After the communication is restored, the protection indicator (yellow) on the panel of the module is restored. When the communication between modules is normal, the module automatically recovers. In order to protect the battery, when the module communication fails, the output voltage of the module changes to 53.5V (different voltages can be preset according to actual needs). 9) Module address conflict If the internal addresses of multiple rectifier modules on the power system are the same, the rectifier modules will generate an address conflict alarm, and the fault indicator (red) on the module panel will turn on. The rectifier module must be replaced.

10. The rectifier module has a built-in advanced digital signal processor DSP, which monitors and controls the operation of the whole module, and communicates with the external monitoring module through the CAN bus.

The details include:

1) You can control the on/off of the rectifier module through the monitoring module and set the output current slow start function and overvoltage protection reset mode of the module.

2) The output voltage, overvoltage point, output slow start time and current limiting point of the rectifier module can be adjusted through the monitoring module.

3) Send input voltage, output voltage, output current, current limiting point, temperature, overvoltage point to the monitoring module;

4) Send the on/off status to the monitoring module, and report the input protection, internal PFC over/under voltage protection, over temperature protection, over voltage off fault, fan fault, temperature power limit, input power limit, current imbalance, module address conflict and other fault information and technical parameters
