Master/Slave Operation

Two or more Model 382260 Power Supplies can be connected in parallel to increase output current
to the sum of the connected supplies. In this mode of operation, the Master power supply will control
all of the voltage and current settings of the Slave units.
1. Set all of the power supplies to the same upper voltage limit (UVL) and voltage/current
range.
2. Set the voltage and current limit of all of the slaves to maximum values.
3. Switch off all of the power supplies.
4. Set the Master/Slave switch to the Slave position on all of the Slave units.
5. Connect the power supplies together using the Master/Slave control circuit on the back of
the power supplies. Note: For proper performance all connecting cables and output cables
should be the same gauge and length.
6. Using either the output terminals on the front or back of the units, connect the output cables
in parallel to the load.
7. Switch on the Master unit first and set to the desired voltage.
8. Switch on the slave units and the Slave Indicator LED will light to confirm correct connection.
9. All output voltages and currents are now controlled by the Master unit.
