ctrlX DRIVE – DC/DC converter XMV2 with resistance loads

The modular drive system ctrlX DRIVE includes the DC/DC converter XMV2 in various current ranges. This enables applications where DC power is supplied or absorbed at user set DC voltage and current setup.

This video provides:
- Brief explanation of the DC/DC converter function.
- Simple examples with
- Resistance load operated at 20 to 275VDC
- AC power ctrlX DRIVE supply XVR2 supplied with
3x240 VAC and regulated DC bus of 400…750 VDC
