Note: The OVP circuit remains active for all units in parallel operation. If the units
are set to different OVP levels, the paralleled system will trip according to the lowest
setting. For ease of use, adjust the OVP levels for the slaves to maximum and adjust
the master OVP level to the desired setting.

SERIES OPERATION

Series operation is used to obtain a higher voltage single output supply
using two units. To set up series operation:
Connect the negative terminal (–) of one supply to the positive terminal
(+) of the next supply of the same model. The total voltage available is
the sum of the maximum voltages of each supply (add voltmeter
readings).
Notes:
•
Under no condition should the negative (–) output terminal of any
power supply exceed 300V to Earth ground. This is limited by the
creepage/clearance distances internal to the construction. If a
