NEW

PLZ6000R is a DC electronic load that regenerates load power to the AC line.
Regular electronic loads consume load power by having semiconductor devices convert it into heat. By
contrast, PLZ6000R converts load power into reusable electric power, rather than converting it into heat as is
typically done, and feeds this power to the AC line, thereby substantially reducing the amount of waste energy.
PLZ6000R is an environment-friendly electronic load that can contribute signifi cantly to your energy saving
efforts.

Applications

Aging and evaluation testing for DC/DC converters and various types of power

supplies
Evaluation and durability testing for alternators and motor generators
Discharge testing for different types of batteries (lead, lithium, and assembled

batteries)
Dummy load testing for equipment powered by natural energy (solar cells and

wind power generation)
Evaluation testing for fuel cells and stacks

[Note] This product is intended for in-plant power generation only. (It does not feed its generated power back to the electric power

system.)
This product cannot be used unless 5.4 kW or more of power is consumed by each power distribution system per one unit.

Functions

Power regeneration efficiency of up to 90%

(at rated power)

The use of a proprietary switching technology (patent pending)
provides high power regeneration efficiency - from 85% or
more at one-third of rated power (2000 W) to a maximum of
90% or more.
This energy saving feature greatly reduces the electronic
load's environment impact on your plant and it is not necessary
to equip special cooling system such as water cooling method
to supress the heat generation.

Soft start function

In constant current (CC) mode, this function causes the load
current to rise gradually when the initial load is at 0 V while the
load of the load unit is on or when the load of the load unit is
turned on. It allows you to conduct tests under highly realistic
load conditions.
[The soft start time can be selected from the following options ­20, 50, 100, and 200 ms.]

Sequence function

This function automatically executes arbitrarily set sequence
patterns step by step (operation by operation). It enables
various types of waveforms to be simulated. (A maximum of 10
programs can be created, each consisting of up to 256 steps.
Operation modes, ranges, loop counts, etc. can be specifi ed in
these programs.)

Auto load off timer function

This function automatically turns off the load current; it is
useful for discharge tests of batteries and other devices.

• Measurement of the time elapsed from the start of discharge
until the fi nal voltage (UVP) is detected (elapsed time display)

• Measurement of the closed circuit voltage after the specifi ed
time elapses from the start of discharge (auto load off timer)

Parallel operation supporting up to 30 kW

A large-capacity system of up to 30 kW can be built using a
parallel connection confi guration with one control unit. (The
system may consist of up to fi ve units - one master unit and
four slave units.)

ABC preset memories

Three preset memories A, B, and C are provided to store and
read up to three different combinations of an operation mode, a
range, and set values.

Equipped with major interfaces

GPIB, RS-232C, and USB interfaces are equipped as standard,
making it easy to integrate the electronic load into a variety of
testing systems.
Support for these interfaces, coupled with the sequence
function, allows you to build diverse types of system.
(The SCPI commands are adopted.)
