1. Outline
PROGRAMMABLE AC/DC POWER SOURCE 2
1.1 Overview
Programmable AC/DC power source KP3000GS is a multifunction power source which can output
3 kVA AC / 3 kW DC at a maximum. It also provides various interfaces such as the external control
input/output, communication interface, and remote controller (optional) to address a wide variety of
usage.
1.2 Features
 Various interfaces to address a variety of usage
The interface to use for the remote controlling from a computer or sequencer is equipped. USB and
RS232 interface are standard, and either GPIB or LAN (LXI 1.4) interface can be chosen when
ordering. You can use a contact/TTL signal to turn the output on/off or switch the memory without
using a computer. The product also offers the status output for showing the device status and the
output which is synchronized with Sequence or Simulation step. With these functions you can
achieve various types of systemization and automatization. The AGC function and Autocal function
for calibrating the output voltage drop are also provided.
 Sequence function
User can program a sequence to change output voltage, frequency, waveforms and so on with this
function, which provides automation of switching continuously a number of testing conditions.
 Power fluctuation test (=Simulation) function
User can simulate power line abnormalities, such as blackout, voltage rise, voltage drop, abrupt
phase change, abrupt frequency change, and so on.

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.
 The power input supports worldwide power supply environments
The KP3000GS supports a wide range of power input from 100 V to 230 V.
 Feature-rich measurement function
On the panel the product 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.
