The PLZ-5WH2 series has the following five Operation modes. In Operation mode other than +CV mode, ” UVPL* ” can be set to control Current so that the voltage does not fall below the UVP setting or less due to excessive current flow, and “UVPT” can be set to load-off. UVPL” is the “+CV mode” in the PLZ-5W series.

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.

Rise time to Rated current is 20A/μs. Supports high-speed transient response tests, which are becoming increasingly important in power supply evaluations. In case of PLZ20005WH2

Parallel operation can be connected with a single parallel operation cable *! Flexible “high capacity” up to 5 units even with different models! (Max. 100kW, 2000A) *Needed between models to be connected. 12kW/20kW models come standard; 1kW/2kW/4kW models are optional.

Operating voltage ranges from 10 V to 1000 V. The minimum operating voltage required to sink current is 1.5 V.

LAN (LXI)/USB/RS232C interface standard *GPIB (option)

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)

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

Set the response speed for CV, CR, or ARB mode according to the DUT’s conditions and application.

“Soft start” is a function that controls the rise time of the load current. “Soft start” functions only when all the following conditions are met:

• The rise time of the soft start has been set.
• “Load on” state is in constant current (CC) mode.
• When there is an input that exceeds the minimum operating condition after the load input terminal has no input.

If the load current rises sharply, the DUT output may become unstable or the DUT’s overcurrent protection circuit may be activated. In such situations, it is possible to make the load current rise slowly only when the device is activated.

The data logging function allows the user to log 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 the timing that measurements are recorded.

Time elapsed, integrated current and integrated power can be logged. 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.

Measurement data can be stored in CSV format to a USB memory device.

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 in progress, a trigger signal is output from the TRIG OUT connector on the front 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.

When the pulse operation is in progress, a trigger signal is output for 10 μs from the TRIG OUT connector on the front panel when the current amplitude changes from low (Depth) to high (Set) level.

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 of whether 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.

When a sine operation is in progress, a trigger signal is output for 10 μs from the TRIG OUT connector on the front panel when the current passes through the Set value on the rising edge (sine wave phase at 0 degrees).

A sequence consists of programs and steps. A program is a collection of steps. Steps are executed in order one at a time, starting from step 1. The completion of the last step signifies that the program has been executed once. When the specified number of program loops is completed, the sequence ends. You can set the load state (load on or off, load value, slew rate) at the end of the sequence of a program.

TALink

The TALink (Transient Acquire Link) trigger makes it possible to log data in PLZ-5WH2 in synchronization with the sequence steps. Logged data can then be accessed through communication with the PLZ-5WH2 and saved to a USB as a CSV file.

This function detects anomalies and protects the DUT. There are two types of alarm based on the urgency level: alarm 1 (high urgency) and alarm 2 (low urgency).

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, which is perfect for when you want to quickly switch between three sets of values.

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
• Load values (current, voltage, conductance, power)
• Slew rate
• Pulse amplitude (current/conductance or percentage)
• Pulse interval (frequency/time of one cycle and duty cycle/operating time on the high side)
• Sine amplitude (current)
• Sine frequency
• Alarm operating conditions
• Content of ABC preset memories

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, this will be changed to +CV mode on the PLZ-5W (PLZ205W, PLZ405W, PLZ1205W).

PLZ-5WH2 can be controlled/monitored from an external device.
The external control terminals are isolated from the load inputterminal.

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.

When a keyboard is connected to the USB connector on the front panel, numbers/characters can be entered from the keyboard.
The types of keyboards that you can use are 101-key and 104-key keyboards.

The following synchronization features are available when simply connecting the PLZ-5WH2 with other equipment using a communication cable. Any of the models in the PLZ-5WH2 series can be connected together. Synchronized operation is possible even during parallel operation.

• Synchronizing load on/off among multiple pieces of equipment.
• Synchronizing measurements.
• Synchronizing the start time and resume time for sequences across multiple units.

With remote sensing, the voltage measurement point can be changed 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 and the operation in CR / CV / CP / ARB mode stabilized.

• Remote sensing input rated voltage: 1000 V
