1.2 Features
Each PAX Power Supply is incorporated or can be optionally incorporated with the various advantageous
features as follows:
(1) Two operating modes
The power supply allows you to select one of the following two types of operating modes.
(a) Fast mode: For rapid rise up and fall down (Selectable for 50
μ s, 500 μ s or 5ms)
(b) Normal mode: For stable operation with low ripple noise (Since no switching actions are in-
volved, the output noise is small.)
(2) Sequence control of output
You can enter sequence control patterns from the local panel or from a personal computer via GPIB
or other interface bus and store them as sequence files on the internal memory. The stored files can be
recalled locally from the front panel or remotely from the host controller via the interface bus.
Control sequences can be programmed in either one of the following two types:
(a) Fast speed sequence: You can program sequences with minimum 100
μ s per step.
(b) Normal speed sequence: You can program sequences with a ramp waveform per step.
(3) Various interface boards (optional)
The power supply can be controlled over a GPIB, RS-232C, or MCB interface bus. This feature, as
combined with the programmed sequence control function, allows you a high flexibility of power
supply system configuration.
The MCB is a unique interface developed by Kikusui. It allows you to control up-to-fifteen instru-
ments (power supplies and electronic load devices) in an on-line mode over a standard interface
system (GPIB or RS-232C).
(4) Ease of operation
Numeric entry keypad, arrow keys, and JOG/SHUTTLE dials are provided on the front panel,to
facilitate entry of numerical values and selection of menu items.
Operation SETUPs of the power supply can be stored in memory and be recalled whenever you need
them. Up to four different types of voltage/current settings can be programmed and stored in differ-
ent locations of memory. This feature is convenient especially when you want to repeat tests with the
same setup of the power supply.
(5) A large backlight LCD
The power supply has a large backlighted-type LCD (liquid crystal display), which displays output
voltage and current settings, readbacks, and other operation data.
(6) Ease of calibration
The power supply can be calibrated easily with the keys on the front panel, without requiring any
sophisticated calibration procedures (but requiring a digital voltmeter and a shunt resistor).

Chapter 1. GENERAL
1-4
(7) Various protective provisions
The power supply incorporates provisions for double-protection with software protectors and hard-
ware protectors against output overvoltage (OVP) and overcurrent (OCP). The software protectors
provide an automatic function that the power supply automatically sets the limit values as you specify
a tolerance of overvoltage or overcurrent in percentage. They also allows you to select either
"POWER switch OFF" or "OUTPUT OFF" for protection when a protector has tripped and the power
supply has fallen into an alarm state.
The power supply also incorporates an overtemperature protector and an input overcurrent protector.
Thus, the various provisions are incorporated to protect the power supply itself and its load.
(8) Analog remote control
You can remote-control the output voltage or current with an external voltage signal or resistance.
You also can remote-control turning OFF of the POWER switch and turning ON/OFF of the output.
The power supply provides various status signals.
(9) Exclusive remote controller (optional)
The remote controller allows you to extend virtually the front panel to a remote position convenient
for you. The control functions of the remote controller are identical with those of the front panel of
the power supply.
