Description

This device is an advanced industrial DC rectifier power supply with variable output power and voltage depending on the model. The system features precise line and load regulation with very low ripple and high efficiency, and uses single-phase and three-phase AC input with a noise filter and full protections including fuse, MCB, surge arrester, and current limiter. The intelligent device controller provides the ability to set the voltage and DC current, fast charging and maintenance modes, and battery temperature compensation. The device's touch screen displays input and output values in real time, and its 19-inch rack installation with an active cooling system makes it suitable for heavy industrial applications in the oil, gas, petrochemical, power generation, and data center industries.
