Product Description

HUAWEI R4850G2 48V 50A Telecom Rectifier Module

 

R4850G2 Brief:

 

The R4850G2 is a digital rectifier that converts the 85~300VAC to 53.5 VDC and possesses the characters of high efficiency, high power density, walk-in start, hot-plug, complete protection, and low noise. The rectifier adopts the latest power monitoring technology, implements the function of monitoring the states of loads and the rectifier status in real time. The output voltage of the rectifier can be adjusted through the host.

Protection

Input overvoltage protection

Protection point:>300 VAC

Recovery range:290–300 VAC

Input undervoltage

protection

Protection point:<80 VAC

Recovery range:80–90 VAC

Output overvoltage protection

58.5–60.5 VDC (can be set by monitoring unit )

If the overvoltage occurs inside the rectifier due to a fault, the rectifier will latch off.

If the output voltage is higher than 63 V and lasts for more than 500 ms, the rectifier will latch off.

Output current limiting protection

See Figure 1.

Output short circuit protection

A long term short circuit is allowed. After the fault is rectified, the rectifier is restored to a healthy state automatically.

Over-temperature protection

The module protects against overtemperature.
