Safety SEM

Subsea Electronic Module

For permanent magnet motors, used typically for actuators for valve operations, and small pumps for hydraulic, grease, and chemical.

The drive is capable to be powered with AC, DC, or simultaneous power supply.

It is fully capable of automatic or manual power feed switching according to the demands or power supply failure.
