5.3 Functions & Features
1. Hot plugging
The rectifier uses hot plugging technology. There is soft-start unit in the input end and output end of the rectifier.
When the rectifier is inserted into the power supply system, the output voltage of the power supply system will not be
disturbed. It takes less than one minute to replace the rectifier.
2. Digital load-sharing
The rectifier uses advanced digital load-sharing technology. There is no need to share the loads through the controller,
they can automatically share the loads between the rectifiers. The imbalance degree of the load-sharing is less than
±3%.
3. Input power limiting
Based on the change of the input voltage, the rectifier uses advanced power limiting method. The change point is
215V (the return difference is less than 3V). When the input voltage is within 154Vac ~ 300Vac, the rectifier can
output the maximal power.
4. Temperature limiting power
In the normal input status of the rectifier, the rectifier can work normally and output the maximum power (1740W)
under the temperature of -40°C ~ +45°C.
5. Fan control
When the input voltage of the rectifier is within the normal range, the rotation speed of the fan will increase with the
rise of the rectifier internal temperature until the fan runs at full speed.
When the AC input is too high or too low, the fan will stop running.
5.4 Fault Protection
1. Input over/under-voltage protection
When the input voltage is lower than 80Vac ± 5Vac or higher than 305Vac ± 5Vac, the protection indicator (yellow)
illuminates, the rectifier will shut down and stop output. When the input voltage returns to the normal range of 95Vac
~ 295Vac, the rectifier will resume work automatically.
When an over-voltage protection event occurs, the rectifier will report it to the controller.
2. Output over-voltage protection
The rectifier has two optional over-voltage protection methods: hardware protection and software protection.
The hardware over-voltage protection point is 58.5V ~ 60V. After the hardware over voltage protection occurs, it
requires manual resetting to restore operation.
The software over-voltage protection point can be set by the controller, the setting range is 56V ~ 59V, which must be
at least 0.5Vdc higher than the output voltage. The factory default setting is 59V.
