1.1 Overview
The programmable AC/DC Power Source GKP-2303 offers a compact, lightweight, and
highly-efficient power system. It also provides various interfaces such as the external control
input/output and communication interface to address a wide variety of uses.
1.2 Features

Various interfaces to address a variety of uses
In addition to the RS232, USB, and GPIB interfaces for remote control from a computer or
sequencer, a contact/TTL signal can be used to turn the output on/off or switch the memory
without using a computer. The GKP-2303 also provides a status output for showing the device
status and output which is synchronized with Sequence or Simulation steps. These functions
allow you to achieve various levels of systemization and automatization. The AGC function and
Autocal function is also provided to compensate for any drop in output voltage.

Variable current limiter
This function can limit the effective value and the positive/negative peak value of the output
current where the limiting value is variable. You can set the limiter so that the output is turned
off when the limited condition continues for a certain time.

Globally adjustable power inlet without restriction by the power supply environment
GKP-2303 supports a wide range of power input from 100 V to 230 V.

Feature-rich measurement functions
On the panel, the GKP-2303 displays the effective value, peak value, average DC value, current
peak-hold value, and active/apparent power of the output voltage/current, the power factor,
crest factor, reactive power, and harmonic current.

USB memory support
You can write/read the following data to/from a commercial USB memory stick:

Basic settings

Sequences

Simulations

Arbitrary waveforms

Restriction of CO
2
emission (= power usage) and the display of CO
2
emission (=
power usage) during operation
By using switching amplifiers, efficiency is improved by about 27% compared to linear
amplifiers. When the power output is low, the internal loss can be lowered by reducing the
number of power units being powered on. A function for calculating and displaying the CO
2
emission from internal losses or from output power is also included.
