Installation and Operation
Sorensen DCS Series 1kW and 1.2kW Supplies
2-12
M362500-01 Rev H
For voltage mode operation, turn the current control fully clockwise and then adjust the
voltage control to obtain the desired output voltage. For current mode operation, turn the
voltage control 1/2 turn clockwise, the current control fully counterclockwise and connect an
appropriately sized shorting jumper across the output terminals. Turn the current control
clockwise until the desired output current is obtained. Turn the power supply off, remove the
shorting jumper, turn the voltage control fully clockwise and turn the power supply on.
Note that for a short period (less than 2 seconds) after power on, the power supply output is
disabled and the current mode LED is illuminated while the main filter capacitors charge
through the inrush limiter.
2.8 Multiple Supplies
DCS Series power supplies of the SAME MODEL may be operated with outputs in series or
parallel to obtain increased load voltage or current. Split supply operation allows two positive or
a positive and negative output to be obtained.
2.8.1
Series Operation
Series operation is used to obtain a higher voltage single output supply using two or more
single units. 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:
1. The maximum allowable sum of the output voltages is 300V. This is limited by the
creepage/clearance distances internal to the construction of the metal shell 25-pin
‘D’ connector mated to J3. If a higher output voltage range is required, contact the
Sales Department or Customer Service for availability.
2. The maximum allowable current for a series string of power supplies is the rated
output current of a single supply in the string.
3. Remote sensing should not be used during series operation.
2.8.2
Parallel Operation
Parallel operation is used to obtain a higher current single output supply using two or more
single units. Set all of the outputs to the same voltage before connecting the positive terminals
(+) and negative terminals (
–) in parallel. The total current available is the sum of the maximum
currents of each supply.
CAUTION
To prevent internal damage, ensure that the OVP trip level of all supplies is
set to maximum.
