The PIA4810 is a power supply controller capable of analog and digital control. It is equipped with the GPIB and RS-232C interfaces and 4 slots, which allow 4 each of PIA4800 Series-specific control boards to be installed. A control board is capable of analog control of 2 channels of DC power supplies or electronic loads; a total of 8 channels can be controlled.
Moreover, DC power supplies with a digital remote-control function, such as the Kikusui PAS, PAM(*1) and PMR Series, can be directly connected to the PIA4830 via a TP-BUS (twisted pair bus), enabling a system up to 32 channels to be controlled digitally.
PIA4820 is an expansion unit that can be connected to the PIA4810 or PIA4830 via a TP-BUS to provide additional control channels. In the same way as the PIA4810, it allows a maximum of 4 control boards to be installed.
Then it is possible to use up to 3 units of PIA4820 as an expansion that can be connected to the PIA4810 via the TP-BUS, the system is capable of controlling a maximum of 32 channels. Moreover, the combined use of the GPIB and TP-BUS allows the system to control a maximum of 448 channels.
PIA4830 is a power supply controller only for digital control. It is capable of digitally controlling a system up to 32 channels of such Kikusui PAS, PAM(*1) and PMR Series DC power supplies via the TP-BUS.
OP01-PIA and OP02-PIA are control boards designed exclusively for the PIA4810 and PIA4820. A single control board is capable of analog control of 2 channels of DC power supplies or electronic loads. The OP01-PIA is a full-control board with voltage and current setting and read-back functions, while the OP02-PIA4800 has only the voltage and current setting feature.
(*1) The TP-BUS interface option is factory installed option, this option should be indicated when ordering.

The PIA4850 is a power supply controller with USB interface to control Kikusui DC power supply with TP-BUS. PAS Series, PWR Series or other models that equips TP-BUS can be digitaly controled by PC, as well as for read-back of output values and status monitoring. It operates using bus power and with its simple system and compact structure, you can use whenever you need with easy setup.
