Page 8: Outline
1. OUTLINE The PR-A Series is a serial control type regulated DC power supply. It is a constant voltage/current power supply whose output can be varied from 0 up to the rated values. It is a compact unit which, provided with both voltage and current calibrated meters, allows both voltage and current to be monitored simultaneously. -

Page 11: Percaution For Use
4. PERCAUTION FOR USE WARNING 1) Confirming the supply voltage ＊Use this unit within the specified range. The unit’s rated voltage is single-phase 100/120/200/220/240VAC ±10% at 50/60Hz. ＊The rated voltage is indicated on the specification and name plate located beside the input connector on the rear panel. 2) Do not remove cover or panel The user never open the case panel whatever may happen. -

5-2. Rear panel ⑭MASTER/SLAVE switch Used during “one-control” parallel operation in the master/slave configuration. During normal operation, the switch should be set to MASTER. (For details, see section 6-3;“Parallel Operation” ) ⑮IN/OUT terminals for parallel operation Control terminals for use in the “one-control” parallel operation mode. ⑯Power cable Approx. -
Page 15: Operation Procedures
6. OPERATION PROCEDURES 6-1. Stand-alone operation ＊When using the power supply in stand-alone, simply operate by manipulation of the panel switches as needed. However , be sure that the MASTER/SLAVE switch is set to MASTER. 6-2. Serial connection ＊Two or more units of the power supply can be hooked up in series to achieve in increase in output voltage. -
Page 16: Parallel Operation (Master-Slave Control)
6-3. Parallel operation (master-slave control) ＊Two or more units of the same machine can be hooked up in parallel to give an increase in output current. The total output current will be the sum of the output currents of the individual machines. ＊In parallel operation, one machine will act as the master and all others will act slaves. - Page 17 Hook-up front panel terminals in the parallel operation modes. MASTER SLAVE(1) SLAVE(2) Note ; I The voltage presets on all the slave machines are set to maximum. The master operates in constant voltage mode and the slaves operate in constant current mode.
