0-10V Analogue interface (standard)

Standard 0-10V remote analogue interface, with potential free contacts for the instructions and statuses

As a standard, our power supplies can be remotely controlled through a 0-10V analogue interface. The interface consists in a single DB-25 connector, located on the rear panel of the power supply.

The remote control cable must be shielded, and we recommend to install a length shorter than 3m.
