The controller’s working voltage range is 12 V to 48 V DC. The voltage limits are 12 V and 50 V DC. If the voltage exceeds 50 V, the controller is guaranteed to fail. If the voltage falls below 12 V, the controller turns off.

The controller was not tested in a vacuum. Most likely, the controller will work in a vacuum, but it is important how the heat will be removed from the body.
