Enhanced 3000W Series 48V-50AMP/24V-100AMP Rectifier

The Enhanced Rectifier is designed for superior performance in Telecom, Industrial and EDP applications. Built-in keypad and LCD make the rectifier locally programmable and also suitable for single unit operation. The Enhanced Series Rectifiers meet the Bell Core standards TR-TSY000947. Overview 19" or 23" shelf mountable, 4 units and 5 units across respectively. Active power factor correction >0.99. Very high power density: >5.5W/inch3. High efficiency: 92% (48V) Current share bus allows plug-and-play without adjustments. Hot pluggability. All major parameters are programmable either locally or remotely. Designed to work with digital or analog control unit. AC input protection by input AC breaker. Output and reverse polarity protection by output DC breaker. Weight 13.28 lbs. (6.04 kgs). UL. CSA and IEC certified.
