Parallel operation
Up to 100kW with parallel operation (Max. 5 units) The PLZ12005WH/PLZ20005WH can be connected in parallel to increase the maximum system capabilities up to 100kW. While connected in parallel, one master unit has complete control of the slave unit(s), allowing the user to control the entire system and monitor all data from the master unit's front panel. Parallel operation requires one optional parallel cable for each slave unit (up to 4). The master and slave unit settings are configured automatically upon connection. Standalone settings automatically return to normal after removing parallel cable and restarting the unit.

Wide ranging operation voltage up to 800 V.
Operating voltage ranges from 10 V to 800 V. Minimum operating voltage required to sink current is 1.5 V.
Rear Panels
Operation modes
The following five operation modes are available on the PLZ-5WH. In addition, in operation modes other than CV mode, it is possible to apply a current (UVPL) or load off (UVPT) by applying a current to reach the target setting voltage.

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. The slew rate can be set as an ammount of current change per unit of time, and measured in the same units for both rise and fall times.
*1 The time it takes to shift from 10% to 90% when the current is Varied from 0% to 100% of the rated current.
Load on/off operation
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
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 are automatically 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.

Pulse function
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 of whether 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. Load value in CC mode or CR en 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).
shown in the equation below. For example, if you specify 9300 Hz, the period set in the device will be n × Δ T = 108 × 1 μ s = 108 μ s (where n is a number set in the device) Converted to frequency, this becomes 1/108 μ s = 9259 Hz.
Sine Function
The sine function alternates the current sinusoidally. This is ideal for superimposed ripple testing for high capacity power supplies and batteries. 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. During sine operation, a trigger signal is output from the TRIG OUT connector on the front panel for 1μs when the current passes through the set value on the rising edge (sine wave phase at 0 degrees).
(Reference) The resolution actually set in the device is period resolution AT = 20 μs, as show equation below. For example, if you specify 900 Hz, the period set in the device will be n × ΔT = 56 × 20 μs = 1120 μs (where n is a number set in the device). Converted to frequency, this becomes 1/1120 μ s = 893 Hz. 4
Sequence Function
The operator can execute a long sequence of predetermined values with the sequence function. A sequence consists of programs and steps. A program is a collection of steps, which are executed in order, one by one, starting from step 1. The program is considered complete after the last step in the program is executed.

● TALink
The TALink (Transient Acquire Link) trigger makes it possible to log data in PLZ-5WH in synchronization with the sequence steps. Logged data can then be accessed through communication with the PLZ-5WH and saved to a USB as a CSV file.
Data Logging Function
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 PLZ- 5WH and a PC. By setting measurement logging conditions, the timing 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
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.
Remote sensing function
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 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. ● Remote sensing input rated voltage：800V
Cutoff Function
The cutoff function allows the user to enable load off once the desired 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.

Synchronized operation
The following synchronization features are available when simply connecting the PLZ-5WH with other equipment using a communication cable. PLZ12005WH and PLZ20005WH can be connected. The synchronization feature is available during parallel operation. ●Synchronizing load on/off among multiple pieces of equipment. ●Synchronizing measurements (remote control). ●Synchronizing the start time and resume time for sequences across multiple units. 【Connection example】
External Control
The PLZ5WH can be controlled and monitored with an external device. The external control terminals are isolated from the load input terminals.
Setup Memory
The setup memory can store up to 20 sets of the settings listed below or alternatively saved on 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-5W (PLZ205W, PLZ405W, PLZ1205W) can be 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 +CV mode on the PLZ-5W.
Soft start function
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. 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.

ABC Preset memories
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.
Current and Voltage Monitor
In addition to the conventional current monitor output, voltage monitor output (0V to 8V/0V to 800V) has been added to the front BNC connector.
