The MS-Series compact bench case DC rectifier provides a constant low ripple of less than 3 % throughout the full output range, to achieve excellent results for any process. Switch Mode rectifiers do not have process limitations like SCR controlled rectifiers.
Type Code: D480 G25/1000 WRG-TFT
The rectifier has a high corrosion protected metal enclosure. Corrosion protection is achieved by a 70 micron-thick e-coating primer inside and outside the enclosure, with a blue green powder coat top layer.
The power circuit is designed for continuous operation at the rated output and therefore especially suitable for industrial applications.
The bench case unit is provided with a 6 ft. AC power cord (without plug) and copper bus bars in the rear of the enclosure for the DC output connections.
Cooling air is taken in from the front and blown out of the rear of the enclosure. Variable speed, thermostatically controlled fans ensure that only the required amount of cooling air is used. This reduces noise and excessive wear of the fans. Cooling air is directed only to electrical components requiring cooling and protects components against corrosive chemical vapors. This gives our bench case rectifiers exceptional service life.
