Parallel/Series
Operation The PSB-L series uses a single power supply unit
(acting as the master unit) to control all connected
slave units for series or parallel operation. In parallel,
up to 4 units can be controlled (including the master)
to increase the total power. In series, a maximum of 2
units (including the master) can be used.
External Control
Function The external control function allows external voltage
and restistance-based control, voltage and current
monitoring, output on/off control, alarm output and
CV/CC status output.
Interface Boards There are two optional interface boards for remote
control.
 PSB-001: GPIB and local bus board.
 PSB-002: RS-232C, USB and local bus board.
Note also that one of these options must be used to
program sequences for the PSB-L series. See page 85
for further details.
