Section 3. Local Operation

Using Multiple Supplies

Configuring Multiple Supplies for Parallel Operation

CAUTION

For parallel operation , set all OVP trip points higher than the maximum output voltage.

Connect power supplies in parallel to obtain a single output supply with a higher output current limit. Set all of the outputs to the same voltage before connecting the positive (+) and negative (−) terminals in parallel. The total current available is the sum of the maximum currents of each supply.

The maximum voltage available at the load is equal to the voltage of the lowest rated supply. When you connect two supplies in parallel, the supply with the higher voltage setting will be in the current limiting mode, while the other supply controls the output voltage.
