Features
R******0U is the rectifier with *5~**0Vac universal and **3.5Vdc output. Its maximum output power is ***0W when **6~**0Vac , and **0W when **0~**5Vac , and **0W when *0~**0Vac .
The rectifier has such protection functions as: over/under-voltage protection, output short-circuit protection, over-temperature protection, current-limit protection and alarm function. The rectifier is hot-pluggable and can be N*1 parallel operation with current sharing.
Other features:
{C}l {C}Acquire the rectifier inner messages through CAN communication
{C}l {C}Pre-current-limit function can protect batteries in a period time after power on
{C}l {C}Intelligent fan speed adjusting.
