12V / 400A DC power supply, 460VAC Rectifier

Compact plating rectifier MS series for wall- or rack mounting installation using an advanced air-cooling system.

A special designed air guiding system, keeping the control electronics out of the air flow  in combination with an automatic fan speed control to adjust the air flow to the required coolings are just three of the features of the applied air cooling system.

Rectifier provides a constant low ripple of up to only 1 % to achieve excellent plating results for any plating process. Process limitations like with SCR controlled rectifiers do not exist anymore.

Double housing construction. Rectifier is built into a separate metal compartment which is surrounded by the double coated metal enclosure with back brackets for wall or rack installation.

The power circuit is designed for continuous operation at the rated output and therefore especially suitable for industrial applications.

The connections for the AC input power, the DC output and controls are realized via terminal bars in the bottom of the wall mount enclosure.
Main Components inside the rectifier:
- Motor circuit breaker
- EMC filter
