Manual for PA18-1.2

1. Outline: Describes the compact and high-performance DC constant voltage/current power supplies with 3.5-digit voltage and 3-digit current LED indicators. Output is adjustable from 0 to rated values via serial control. Features coarse/fine adjustment, digital display, output on/off, and remote sensing functions. 2. Features: Highlights low ripple and noise, voltage/current concurrent digital LED display, and increased output capability through serial/parallel operation. Also notes floating output, output sensor terminals, and systematization via remote controls. 6. Operation Procedures: 6-1 Single operation: Perform panel operation, ensuring rear switches are set to MASTER/LOCAL. 6-2 Remote sensing: For fine load terminal voltage setting, insert sensor plugs. Note that in normal use, the plug should not be inserted. 6-3 Various remote control functions: Details remote control application functions, including master/slave and LOCAL/REMOTE switch settings. 6-4 OUTPUT on/off remote control: Controlled by an external contact signal. 6-5 Constant voltage remote control: Via external voltage (0-10V) or external fixed resistance (0-10 kΩ). 6-6 Constant current remote control: Via external voltage (0-10V) or external resistance (0-10 kΩ). 6-7 Serial/parallel connection: Explains how to increase output voltage (serial) or current (parallel) by connecting multiple units. 6-8 One control parallel operation: Master machine controls parallel slave machines. 6-9 One control serial operation: Master machine controls serially connected slave machines to increase output voltage. 7. Maintenance: Instructions for removing the case, changing power voltage, and replacing fuses. 8. Troubleshooting: Table listing common troubles, check points, and causes.
