6-2. USE FOR PARALLEL CONNECTION
All of the same models of the PR/PD series can be operated for maximum of 5 units in parallel:
(1) Before turning on the power, please connect proper number of units based on your needs of current capacity.
(2) Total output current = SLAVE4
6-2-1. Connect APG of 2 units to the circuit board
Refer to the figure below for parallel use.
(1) If there is no parallel circuit board, follow the wiring method below to connect analog programming ports in each
DC power:
(2)
Please refer to “Wiring introduction” for the appropriate
wire diameter. According to the wiring diagram, use
the same length of the wire to connect the output terminals of power supply to the load. The length of
the wire that is connected to the load should be as short as possible, and it should verify the
connection of APG control terminals in each unit.
Attention!! Please verify the output terminals of the MASTER and the SLAVE are connected
with the same polarity.
