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.
Description
R******0U is single-phase, hot pluggable, fan-cooled rectifier. The high power density of this product offers the optimum 3U shelf solution for space-critical applications.
Rectifiers offer excellent efficiency as well as wide operating temperature and wide voltage range. Together with advanced technology they enable cost effective and reliable solutions. The typical applications for this rectifier are both in indoor and outdoor environments, which is ideal for broadband access, cable head ends, BTS cells, Enterprise and GSM applications.
