HR7 High Frequency Rectifier

HR7 High Frequency Rectifier


When the application requires ‘real’ power, HR7 can deliver efficient, reliable, and  regulated power as small as 5KW and up to 2.5 MW.


Utilizing the latest in IGBT technology, HR7 is capable of constant or variable power with very low output ripple and minimal harmonic disturbance on the input.


Touch screen HMI allows for ease of monitoring and control, while providing diagnostics and historical information regarding the unit.


Batteries and input/output voltage and current measurements are among other features easily and readily accessible through this panel.
