One-Control Parallel Operation
＊
It is possible to control units connected in parallel (i.e., two slave
units) and increase their output capacity from one unit (master unit).
＊
The total output current capacity is the sum of the output current
of each slave unit.
1) Turn off power of all master and slave units.
2) Set the MASTER/SLAVE switches on the front panels of all
slave units to the S position.
3) Connect the parallel operation terminals (IN/OUT1/OUT2) on
the rear panels of the master and slave units as shown in the
drawing.
4) Connect the output terminals of the power supply units with the
load using cables of the same length as shown in the
connection diagram.
5) Rotate the voltage control of all slave units fully clockwise.
6) Throw the POWER and OUTPUT switches of the slave units.
7) Throw the POWER and OUTPUT switches of the master unit.
The output voltage and current may be set freely with the
voltage and current controls of the master unit.
NOTE 1: -The CV or CC LED of the master unit shows the output mode.
- On the slave units, the CC LEDs are always lit.
NOTE 2:-Connect the GND terminal with the (+) or (-) terminal. This
commonly applies to the master and slave units. (The
output connection diagram below shows the (-) grounding
connection.)
NOTE 3: -In parallel operation, it may sometimes be impossible to
vary the output voltage on the master unit when the output
reaches 0 A. Use the master unit so that several % or
more of the rated current always flows.
NOTE 4:-Set the controls of the slave units to the maximum positions
in parallel operation.
＊
Control the master unit only in remote control.
