9. PARALLEL OPERATION

Parallel operation of units with the same voltage and current ratings is possible using the

non-isolated analog interface. The interface must be installed on both units.

Parallel Master Slave operation with the Remote Analog Interface – Option 1

9.1.

For basic parallel Master Slave operation, the set values for Voltage and Current on the

Master supply are used to program the output voltage and current of the Slave unit.

Connect Master Pin 4 to Slave Pin 8 for the Voltage channel, and Master Pin 5 to Slave Pin

15 for the Current channel. Hard wire Slave Pin 12 to Slave Pin 6 to turn on the HV output.

The HV output cables must be connected together at the load.

Parallel Master Slave operation with the Remote Analog Interface – Option 2

9.2.

Connect the current monitor output of the Master (Pin 3) to the Current Program Input of the

Slave (Pin 15). The output voltage of the slave is set to the rated value by hard wiring the

Slave connector Pins 8 and 10 together. Hard wire Slave Pin 12 to Slave Pin 6 to turn on the

HV output. This connection ensures current sharing with parallel units. The Voltage set point

is controlled by the Master supply either in Local or Remote control as required.
