Series Operation

Series operation is used to obtain a higher aggregate output voltage using two units.
Each supply is operated individually, and is set up as follows:

Connect the negative terminal (

–) of one supply to the positive terminal (+) of the next

supply; both units must be of the same model. The total voltage available is the sum
of the maximum voltages of each supply. Each supply displays its own output voltage,
and the load voltage is the sum of each front panel display.

CAUTION!

Under no condition should the negative (

–) output terminal of any power supply

exceed 600 V to chassis (earth) ground. This is limited by the isolation and
creepage/clearance distances internal to the power supply construction. If a
higher output voltage range is required, contact the factory for availability.

Note:

1.

The maximum allowable current for a series string of power supplies is the rated
output current of a single supply of the string.
