5.5.2 User I/O Connection
The LPX Power Supply is equipped with a standard external connection to allow you to
design and connect your own custom interface for controlling the unit. The User I/O
interface can be useful when you need to activate the LPX Power Supply remotely, for
example, when the operator must start and stop the unit from another room for safety
reasons.
1. All voltages and currents measured with respect to Pin 7, Common, except Seek +/-, which is measured
Pin 8 (+) to Pin 9 (-)
2. Outputs should never drive impedances less than 1.6 KΩ
