Product Description

Rectifiers bring advanced technology to the DC power industry. Innovative engineering combines the best in efficiency and reliability to meet the power requirements for a variety of system applications. This rectifier is specifically designed to recharge all types of stationary batteries for large utility, petrochemical and industrial uses.
The fan cooled rectifier module has extremely high density providing the most power in the least amount of space. A compact shelf accommodates four rectifiers per 19in 2U shelf and can be paralleled up to 5*2U 19in shelf. Local and remote setup, adjustment and control is a simple, single-step process with the rectifier System Controller. By utilizing TCP/IP technology, complete configuration and monitoring of power equipment is possible through a standard web browser.

Detailed View

High Frequency Switching Technology The converter utilizes High Frequency (20 KHz and above) techniques. It features resettable fuses for circuit protection and built-in time delay/hysteresis to avoid hunting during power cycles.
Intelligent Cooling & Protection Temperature-controlled DC fans provide forced cooling. In case of fan failure, the module automatically shuts down above 70°C and restores when temperatures drop, ensuring no fire hazards.
Auto Float & Boost Mode Capable of operating in "Auto Float cum-Boost charger" mode based on battery conditions. Maintains DC output voltage within ±1% across the specified load range.
