Whileconnected in parallel, one master unit has complete control of theslave unit(s), allowing the user to control the entire system andmonitor all data from the master unit's front panel. Parallel operation
requires one optional parallel cable for each slave unit (up to 4). The

Functions

Operation modes

Pulse function

The following five operation modes are available on the PLZ-5WH.
In addition, in operation modes other than CV mode, it is possible toapply a current (UVPL) or load off (UVPT) by applying a current toreach the target setting voltage.
Constant current(CC) mode

A current value is specified and the current is kept constant evenwhen the voltage changes.

Constant resistance(CR) mode

A conductance value is specified and the PLZ-5W sinks current
proportional to the voltage variation.

Constant voltage(CV) mode

A voltage is specified and the PLZ-5W sinks current so that thevoltage at the load input end of the PLZ-5W is constant.

Constant power(CP) mode

A voltage is specified and the PLZ-5W sinks current so that thepower consumed inside the electronic load is constant.

Arbitrary I-V
characteristics(ARB) mode

The desired load characteristics can be set by specifying multiple
arbitrary voltage values and current values as I-V characteristics.

The pulse function is defined as the rapid transition of two settings
alternating repeatedly. This setting is suitable for dynamic transient
tests for high capacity power supplies and batteries. During pulse
operation, a trigger signal is output from the TRIG OUT connector on
the front panel (p.36). These settings can be changed regardless ofwhether the load is on or off in both CC and CR modes. The pulse
amplitude can be set either as a number or a percentage of the load
setting values.

During pulse operation, the front panel TRIG OUT connector outputs
a trigger signal for 1μs when the current is changed from LOW(Depth) to (High).

Adjustable slew rate
With the PLZ-5WH, the slew rate, or speed at which current
changes, is programmable. The slew rate setting will function under
the following circumstances:●When settings are applied to change the current value(including the pulse function).
●When the current value is changed via external control in CC mode
●When the current value is changed while the load is on.

     Converted to frequency, this becomes 1/108 μ s = 9259 Hz.

Sine Function
The sine function alternates the current sinusoidally. This is ideal forsuperimposed ripple testing for high capacity power supplies andbatteries. During sine operation, the front panel TRIG OUT connector
outputs a trigger signal (p.36). These settings can be changed
regardless of whether the load is on or off in CC mode, but the slew
rate cannot be set. The sine amplitude can be set as a number.
Current
Amplitude [A]● Start with "load on" when power is turned on● Display elapsed "load on" time
● Auto "load off" when time limit is reached● Control "load on/off" with external controls such as relays

Arbitrary I-V characteristics (ARB) mode
In ARB mode arbitrary I-V characteristics can be set by entering
multiple I-V points (voltage and current value set points). 3 to 100
points can be registered and the spaces between all points areautomatically linearly interpolated. The minimum voltage (0.00V)
and maximum voltage (808.00V) are fixed. This mode can be used
for the simulation of LED drivers and other DUT's with non-linear
characteristics.

n × ΔT = 56 × 20 μs = 1120 μs (where n is a number set in the device). Converted to frequency,
this becomes 1/1120 μs ≈ 893 Hz.

Functions

Sequence Function

Remote sensing function

The operator can execute a long sequence of predetermined values
with the sequence function. A sequence consists of programs andsteps. A program is a collection of steps, which are executed inorder, one by one, starting from step 1. The program is considered
complete after the last step in the program is executed.

With remote sensing, the voltage measurement point can bechanged from the load input terminal to the DUT sensing point.
By connecting the sensing leads to the DUT, the effects of voltage
drops caused by resistance in the load cables can be reduced andthe load current stabilized. To activate remote sensing, connect
the sensing cables to the sensing terminals of the PLZ-5WH at the
DUT end, and enable the remote sensing function.

Up to 1000 steps total can be used in all programs
Set a program for each operation mode. Up to 30 programs can be set.

The data logging function allows the user to log measurement values
in the internal memory, and display logged data on an LCD screen(Table) as a chart (Chart). It can also be stored in CSV format on
a USB and acquired through communication between the PLZ5WH and a PC. By setting measurement logging conditions, thetiming for data logging for each measurement can be controlled
and synchronized between synced devices. Additionally, log
measurements can be made when the load is off, meaning that test
results such as battery discharge capacity (Ah) can be measured
and stored as CSV data onto a USB.

Integrated Data Function

External Control

Time elapsed, integrated current and integrated power can belogged. Logging (integration) can be coordinated to start/finish
when the load turns on/off or during the start or end of a sequence.
Logging can also be controlled arbitrarily.

The PLZ5WH can be controlled and monitored with an external
device.
The external control terminals are isolated from the load input
terminals.

Functions

Setup Memory

Soft start function

The setup memory can store up to 20 sets of the settings listed below oralternatively saved on a USB memory device.

The soft start feature controls the rise time of the load current. The
soft start feature can be activated when the following conditions are
met:●The rise time of the soft start has been set.
●"Load on" while in CC Mode.
●Soft start input settings start from zero input and end equal to or
above the minimum operating conditions.

Input voltage
or input current

A file saved on the PLZ-5W (PLZ205W, PLZ405W, PLZ1205W) canbe transferred to the PLZ-5WH via a USB memory device. If the
UVP is set to "limit" on the PLZ-5WH, this will be changed to +CVmode on the PLZ-5W.

This function can be used if the output of the DUT becomes
unstable when the load current rises sharply, or when the operator
wishes to delay the current change on startup to prevent the DUT's
overcurrent protection circuit from being activated.
