1-4 General Information PLZ-4W
1.4 Features
In addition to the high-performance constant current, constant resistance, and con-
stant power modes, the PLZ-4W Series Electronic Load offers wide variety of other
features.
■ High-speed slew rate of 16 A/ μ s (PLZ1004W)
The rise and fall slew rate of the current when switching at 2 % to 100 % (20 % to
100 % in M range) of the rated current in constant current mode is 16 A/ μ s
(PLZ1004W), which converts to rise and fall times of 10 μ s (all types).
This allows you to conduct more accurate DC power transient response tests and to
generate simulated waveforms for use as dummy loads.
■ Variable slew rate
Unlike the conventional electronic loads that were configured using rise and fall
times, the PLZ-4W allows configuration using slew rates (A/ μ s) in constant current
and constant resistance modes.
This allows you to optimize the voltage drop caused by the wire inductance that
occurs when a load is switched or the transient control of the equipment under test
(such as a constant voltage power supply).
■ Higher precision
Higher precision is offered for current settings.
Resolution at low current settings is provided using a 3-range configuration. (A 0.01
mA resolution is possible at the L range of the PLZ164W.)
■ Operability
The PLZ-4W employs a large LCD.
Measured values of voltage, current, and power at the load input terminal are indi-
cated at all times. The values are indicated using larger characters than other sec-
tions to improve the visibility.
Coarse and fine adjustments using the rotary knob are useful for setting values over
a wide range.
The easy-to-use memory function enables repetitive tests.
■ 0 V input type
A 0 V input operating voltage type is available.
This feature is a must for single cell tests of fuel cells. Moreover, the operating volt-
age of semiconductor devices is decreasing more and more due to the reduction of
the power consumption and miniaturization of the semiconductor process. The 0 V
input type can be used to evaluate the power supplies for these types of applications.
■ Sequence function
Sequence patterns set arbitrarily can be saved to built-in memory.
Up to 10 normal sequence programs and 1 fast sequence program can be saved. Up
to 256 steps and 1024 steps can be saved for each normal sequence program and
fast sequence program, respectively.
