0-10V Isolated Analogue interface

0-10V analogue remote interface designed to separate the 0V reference of the remote control interface from the chassis ground of the power supply.

Digital and analogue 0V references are isoltated from the chassis ground (isolation voltage : 500V). The interface consists in a single DA-15 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.
