Efficient current conversion in a compact form

A rectifier converts alternating current (AC) to direct current (DC) and provides the power necessary to charge batteries. With a focus on continuously improving the total cost of ownership, Delta’s rectifiers, combined with advanced control and monitoring features, help reduce both capital and operational expenditure. Our rectifiers boast an industry-leading power density while fulfilling space and weight requirements. They leave plenty of room for other equipment and create savings in packaging and transportation costs. In addition, their high efficiency lowers total energy consumption and reduces the environmental footprint.

Delta’s rectifiers are easy to install, as their connectors are located at the rear and are hot-pluggable. Fan cooling with speed control renders operating almost silent. In general the rectifiers include a wide AC input voltage range, protection against AC overvoltage and optional protection against loss of neutral, which make this solution very reliable even in the regions with AC utility network problems.

The EnergE rectifiers meet the new standard of energy efficiency.
