Operation Modes[Specifications: See P.8-9]

The following five operation modes are available on the PLZ-5WH2.
In operating modes other than CV mode, you can also set “UVPL,*”
which controls the current, so that the voltage does not drop below theUVP setting value, and “UVPT,” which turns off the load so that thecurrent doesn’t overflow.
Constant current(CC) mode

When a current value is specified, the current is kept at thatvalue even when the voltage changes.

Parallel Operation
Up to 100 kW with parallel operation (Max. 5 units)
Parallel operation (max. 5 units) is available on all models by simply
connecting an optional parallel operation cable. This feature is available
even among different models for a wide range of high power.
(up to 100 kW / 2000 A)

Constant resistance When a conductance value is specified, the product sinks the current proportional
to the voltage variation by using the value as a proportionality constant.
(CR) mode*A parallel cable is required to connect each unit. It is a standard accessory
for 12 kW and 20 kW models, and optional for 1 kW/2 kW/4 kW modes.

Constant voltage(CV) mode

When a voltage value is specified, the product runs the current
so that the voltage is kept at that value.

●Connection conceptual diagram

Constant power(CP) mode

When a power value is specified, the product runs the current
so that the power is kept at that value.

Arbitrary I-V charac- The desired load characteristics can be set by specifying multiple

In ARB mode, arbitrary I-V characteristics can be set by registering
multiple I-V characteristic points (pairs of voltage and current values).
Vales can be registered from 3 to 100, and linear interpolation is
performed between the values. Minimum voltage (0.00V), current(0.00A) and the maximum viktage (1010.00V) are fixed.

Load On/Off

Data Logging Function

The following load on/off settings are available in addition to standard
operations that can be carefully adjusted to fit the needs of any test
environment.
● 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● "Load off" by specifying conditions (Cutoff function)

Cutoff Function[Specifications: See P.11]

The cutoff function allows the user to enable "load off" once the elapsed
time/voltage drop/integrated current/integrated power has been reachedafter "load on". Multiple factors can be selected, with load off being
implemented after the first requirement is met.

The data logging function allows
t he user to lo g measurement
values (current, voltage, power) in
the internal memory, and display
logged data on an LCD screen(Table) as a chart (Chart).
By setting measurement recording
conditions, you can control thetiming that measurements arerecorded.

Functions

Pulse Function[Specifications: See P.9]

Pulse function refers to the operation of executing two settings repetitively.
It is suitable for transient response characteristics testing of large
capacity power supplies and batteries. When the pulse operation is inprogress, a trigger signal is output from the TRIG OUT connector on thefront panel. You can set this regardless of whether the load is on or off.
This function operates in CC and CR modes. The pulse amplitude is set
with a value or a percentage of the load value.

Sequence Function
A sequence consists of programs and steps. A program is a collectionof steps. Steps are executed in order one at a time, starting fromstep 1. The completion of the last step signifies that the program has
been executed once. When the specified number of program loops iscompleted, the sequence ends. You can set the load state (load on oroff, load value, slew rate) at the end of the sequence of a program.
Set a program for each operation mode. Up to 30 programs canbe set.Up to 10000 steps total can be used in all programs.

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

Sine Function
The sine function varies the current sinusoidally. It is suitable for superposed ripple testing of large capacity power supplies and batteries.
When a sine operation is in progress, a trigger signal is output from the
TRIG OUT connector on the front panel. You can set this regardless ofwhether the load is on or off. This function operates in CC mode.
You cannot set the slew rate. Set the sine amplitude with a value.

ABC Preset Memories

Current and Voltage Monitor

Three setting values can be stored in preset memory slots A, B, and
C. All saved settings can be accessed at the press of a button, whichis perfect for when you want to quickly switch between three sets ofvalues.

In addition to the conventional current
monitor output, voltage monitor output(0 V to 10 V/Output of 1/100 of measured
voltage) has been added to the front BNC
connector.

Setup Memory
The setup memory can store up to 20 sets (0 to 19) of the current
conditions of the items listed below. The current conditions can also be
saved in a USB memory device.
● Operation mode

USB Keyboard
You can enter numbers/characters if you connect a keyboard to the
USB port on the front panel.
The types of keyboards that you can use are 101-key and 104-key
keyboards.

A file saved on the PLZ-5WH2 can be transferred to the PLZ-5W via a
USB memory device. If the UVP is set to "limit" on the PLZ-5WH2, thiswill be changed to +CV mode on the PLZ-5W (PLZ205W, PLZ405W,
PLZ1205W).
