Kikusui PAN 110-1.5A, Operation Manual

Page: 104 / 160

4-44 PAN-A
• Assign the PAN-A series as the master unit.
• Slave units may be either PAN-A series or PAN series.
• For external resistor (Rext), use a 1 W or larger metal
fi lm or
wire-wound type resistor with a good temperature coef fi cient
and small aging effect.
• An external resistor (Rext) is required only when connecting
the PAN-series power supplies to each other.
Starting master-slave-control series operation
• To start master-slave-control series operation,
always follow the procedure below. The slave units
are under control of the master unit, so do not turn on
the POWER switches of the slave units
fi rst.
1. Check that the OUTPUT switch of each unit is turned off.
2. Turn on the POWER switch of the master unit.
3. Turn on the POWER switch of each slave unit.
4. Turn the VOLTAGE control knob and the CURRENT control
knob of each slave unit fully clockwise.
• Preset the output of each slave unit to the maximum level, so
that it can follow the preset output of the master unit.
5. While pressing the LIMIT switch of the master unit, preset
the output voltage and current.
• The total output voltage setup value can be found by multi-
plying the preset value of the master unit by the number of
units used for the series operation.
6. Turn on the OUTPUT switch of the slave unit.
"CV" lights up on the slave unit control panel, indicating that the
unit is in constant voltage operation mode.
