Regeneration efficiency of PLZ6000R
Load power [W]
Regener
ation efficiency [%]
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.

Functions
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.]
Regenerated power values recognizable at a
glance!
The large-size LCD panel displays regenerated power values
in real time.
This makes the energy saving effect much easier to recognize.
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.)
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.)
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.
Suppor t for these interfaces, coupled with the sequence
function, allows you to build diverse types of system.
(The SCPI commands are adopted.)
