In a live power system, inserting or pulling out the rectifier module will not cause sparks or damage terminals. The replacement time of the rectifier module is less than 1 minute, ａnd the impulse current is less than 1.5 times of the rated input steady-state peak current.

Input limited power control rectifier module adopts *** limited power control method, ａnd its output power varies according to the change of input voltage ａnd output voltage. When the input voltage is 176Vac~290Vac (the backlash is less than 3V), the rectifier module can output *** power (2900W); when the input voltage is 85Vac~176Vac, the module works normally, but will enter the limited power mode. 维谛R48-3000e3通信电源，维谛R48-3000e3整流模块，维谛R48-3000e3模块50A，维谛R48-3000e3电源-48v 4. Output characteristic *** Output power is 2900W when the output voltage is between 48V ａnd 58V. When the output voltage is below 48V, the output current is maintained at 60.5A.

If the second overvoltage occurs within the set time (default is 5 minutes, which can be set by the monitoring module), the rectifier module will be shut down ａnd maintained. Manual intervention is needed to start the rectifier module. If the output current of the rectifier module is less than 5A, the rectifier module will not shut down. Manual intervention method: the rectifier module can be reset by monitoring module, or can be reset by disconnecting the rectifier module from the power system.  7. Over-temperature protection reduces the output power to 50% of the rated value when the internal temperature of rectifier module exceeds 85 C due to blocked intake, high ambient temperature or fan failure. When the internal temperature of the rectifier module reaches 90 C, the *** indicator of the panel will be on ａnd the rectifier module will stop working.
