| Technical specification | High efficiency plating rectifier featured with our advance IGBT technology to achieve high quality DC power (gamma M).The forced air-cooled rectifier is designed as a 19" module and is intended for remote control via analogue signals 0 - 10 V. Type: D400 G25/600 WRG-TFM One of the outstanding features of this compact power supply is the constant low ripple of less than 3% which provides excellent DC quality and is ideal for precision plating processes. The unit is rated for continuous, full load, industrial operation without any reduction in output power. Design: The rectifier is designed as a tough, modular plug-in unit in a metal casing. Connections for AC power and control are realised via terminal bars mounted in the front of the module. DC output is via solid copper bars, also mounted in the front. Advanced cooling and protection circuit: The impact of the plating line's corrosive atmosphere is considerably reduced by two of this rectifier's special features, extending the unit's life expectancy. Firstly, the cooling air flow is guided along the heat-sink, keeping it and any foreign bodies (especially dust) separate from the power components. Secondly, the risk of contamination being introduced by the cooling air is further reduced by the integrated air flow control system which calculates and supplies the exact amount of air needed to keep the rectifier at its optimum temperature.
