PLZ164WH
PLZ334WH
PLZ1004WH
The PLZ-4WH Series Electronic Load is a multifunctional system
designed to offer the highest levels of reliability and safety. The
electronic load contains a stable and high-performance current-control circuit that enables high-speed load simulations. In addition, its
CPU control feature works to improve operability and multifunctional
capability. The high-precision current settings provide you with suf-
cient resolution. Because the electronic load comes standard with
GPIB, RS232C, and USB communication functions, it can be easily
incorporated into a wide range of test and inspection systems.

Features
Safety Symbols
In addition to the high-performance constant-current, constantresistance, constant-voltage, and constant-power modes, the PLZ4WH Series Electronic Load offers a wide variety of other features.
• Variable Slew Rate
The rise and fall slew rate of the current when the PLZ-4WH
switches at 2 % to 100 % (20 % to 100 % in M range) of the rated
current in constant current mode is 0.8 A/μs (PLZ1004WH), which
corresponds to fast rise and fall times of 50 μs (for all types).
This allows you to conduct accurate transient-response tests of
DC power supplies and to accurately generate simulated waveforms for use as dummy loads.
In constant current mode, the PLZ-4WH allows conguration using slew rates (A/μs).
This allows you to optimize the voltage drop caused by the wire
inductance that occurs when a load is switched or to optimize the
transient control of the equipment under test (such as a constantvoltage power supply).
• Higher Precision
Higher precision is offered for current settings.
High resolution for minute current settings is provided using a
3-range conguration. (A 0.003 mA resolution is possible in the L
range of the PLZ164WH.)
• Operability
The PLZ-4W employs a large LCD.
Measured values of voltage, current, and power at the load input
terminals are indicated at all times. The values are indicated using
larger characters than other sections to improve visibility.
Coarse and ne adjustments using the rotary knob are useful for
setting values over a wide range.
The easy-to-use memory function enables repetitive tests.
• Sequence Function
User-defined sequence patterns can be saved to the internal
memory.
Up to 10 normal sequence programs and 1 fast sequence program can be saved. Normal sequences can contain up to 256
steps, and the fast sequence can contain up to 1024 steps.
You can edit sequences easily from the large LCD.
• Functions that are useful for battery discharge testing
You can measure the time from when the load is turned on until
when it is turned off.
You can measure the time from the start of battery discharge to
the cutoff voltage (time measurement) by using this function in
conjunction with undervoltage protection (UVP).
In voltage measurement, the voltage immediately before the load
turns off is measured. If you use the timer so that the load turns
off after a specied amount of time, you can measure the closedcircuit voltage after a specied time has elapsed since the start of
battery discharge (voltage measurement).
• Load booster
To achieve large capacity at low cost, the PLZ1004WH comes
with a load booster (PLZ2004WHB).
Using a single PLZ1004WH as a master unit, up to four load
boosters can be connected in parallel (9 kW, 450 A maximum).
• Standard-equipped GPIB, RS232C, and USB interfaces
The PLZ-4WH comes standard-equipped with GPIB, RS232C,
and USB interfaces. It can be easily incorporated into a wide
range of test and inspection systems.
When the interfaces are used with the sequence function, a vari-
ety of systems can be created.
For the safe use and safe maintenance of this product, the following
symbols are used throughout this manual and on the product. Note
the meaning of each of the symbols to ensure safe use of the product. (Not all symbols may be used.)
