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-backof output values and status monitoring.
It operates using bus power and with its
simple system and compact structure,
you can use whenever you need witheasy setup.

The TP-BUS utilizes a daisy-chain connection.
This makes adding power supplies easy and keeps
cables neatly together.

*1: The maximum controlable units are 31 when the connections include PAM series or PMR series unit.
*2: TP-BUS (Twist-Pair BUS) is an original Kikusui interface.

Sequence Creation Software

Wavy

Creating sequence conditions
The sequence can be created inone of two ways: either by using themouse or by numerical input!!

Comingsoon!

Wavy for PAS&PWR
This software supports to create and execute sequences of DC power supply.
Sequences can be created and edited by drawing with the mouse or by inputting in aspreadsheet.

■ Easily create and edit the test conditions data for sequence operation.
■ Easily manage test conditions template using the function for saving test condition data files.
■ The execution graph function displays the execution status as a cursor on the settings graph,and can be used to verify the progress of the execution sequence.
■ Easy to monitor the actual output using the monitor graph function that plots the monitored
output values during test execution.
■ The acquired monitor data can be saved as the test results.
Operating environment: Windows Vista/XP/2000*Refer to the Kikusui products catalog and website for detail of Wavy.

What kinds of commands are used to perform The commands vary depending on the power supply
power control?
that is being controlled. The commands are listed in theinstruction manual that was provided with the power
supply unit. The instruction manuals can also be viewed
at the Kikusui website.
What is the communications speed? (Howmuch time is required for one command?)The control time varies depending on the power supply
that is being controlled, and also on the number ofcontrolled power supplies and the PC performance.
As an example, when controlling one PWR series unit,
approximately 100 ms are required in order to send thecommand and start operation of the device.

Is it possible to operate devices other than
Kikusui VISA?

The PIA4850 conforms to USBTMC specifications.
VISA from other companies that include compatible
drivers can also be operated.
* USBTMC stands for USB Test & Measurement Class.

Note: F or power supply with analog control function, refer to the PIA4800 Series catalog orcontact Kikusui.
