The current trend in semiconductors is towards lower voltages and higher speeds. This trend places similar demands not only on the components of semiconductor power units, such as switching power supplies, batteries, and DC/DC converters, but also on the electronic loads used for testing. Research and development in the ﬁeld of fuel cells, which are expected to become an eco-friendly source of energy, demands electronic loads that allow a current to ﬂow even at 0 V, as well as load systems with expandable capacity for testing stacks of cells. The PLZ-4W Series of electronic loads has been developed to satisfy all these demands.

The PLZ-4W Series offers high-performance DC electronic loads capable of operating in six modes: constant current, constant resistance, constant voltage, constant power, constant current + constant voltage, and constant resistance + constant voltage.

In addition to offering high-speed response at a maximum slew rate of 16 A/μs* of 10 μA* an ABC preset memory function, 100 setup memories, and a sequence function. What’s more, timer functions combined with time/voltage measurement functions allow you to measure battery discharge characteristics.

Also provided is a master/slave parallel operation capability* power capacities according to the output of the device under test. The PLZ1004W can handle up to 9 kW and 1800 A through the use of dedicated booster units (PLZ2004WB).

For communication, the system is provided with GPIB, RS-232C, and USB 2.0 interfaces as standard. Each of these interfaces supports IEEE 488.2 as well as the Standard Commands for Programmable Instruments (SCPI), developed for testing and measuring instruments.

Support of 0-V input

PLZ164WA and PLZ664WA are 0-V input operating voltage models. This feature is indispensable for testing single-cell fuel cells. The continuing trend toward lower power consumption and semiconductor process miniaturization is driving semiconductor devices to operate on increasingly lower voltages. These models are suitable for evaluating such power supplies.

* This product detects a ‘no-input’ state when the input voltage is below about 0.3 V

and when the input current is below about 1% of the range rating. Therefore, if the input voltage is raised gradually from 0 V, no current ﬂows until the input voltage exceeds 0.3 V. If a current exceeding 1% of the range rating ﬂows, it is possible to have a current ﬂow at less than 0.3 V.

* PLZ164WA and PLZ664WA have bias supplies inside their chassis. In the case of

a power supply in which a diode is arranged in the direction from the minus output to the plus output, such as a switching power supply, if the output of the power supply of the device under test is turned off with this system’s load on, the current ﬂows from the bias supply to the diode, generating a reverse connection alarm.

Variable slew rate

The slew rate determines the slope of change in the current when the set current needs to change sharply as in a transient response test. This system lets you set the current change rate per unit time as appropriate for the selected current range.

• Shift in the current waveform with the change in the slew rate

* Adequate slew rate performance is guaranteed as long as the change in the current

remains within the 2%-to-100% range of the rating. The maximum rise time is limited to 10 μs. If the change in the current is small, the slew rate value may not be stored for the reason stated above.

High precision and high resolution

The built-in three-range configuration provides both wide dynamic range and high precision. The voltmeter, ammeter and wattmeter functions that display values using up to ﬁve digits each and a minimum setting resolution of 10 μA (for the PLZ164W/164WA L range) are implemented.

Control Functions and Operation Support Functions

Load on/o operations

In addition to the regular operations, the following types of load on/off operations are available. You can choose any of these operations as suitable for your operating environment.

• Start in the load on state

• Display of the elapsed load on time

• Auto load off after the elapse of the set time

• Load on/off control using relay and other external signals

Sequence function

Any sequence patterns can be stored in the built-in memory. The memory can hold up to 10 normal sequence programs plus one fast sequence program. Each normal sequence program can contain a maximum of 256 steps, with the fast sequence program consisting of up to 1024 steps. You can edit these programs on the large liquid crystal display (LCD) monitor.



Normal sequence

A different execution time can be assigned to each step individually. You can stop the execution of the sequence temporarily using PAUSE and remove the pause using an external trigger signal.



Fast sequence

Each step is executed at high speed. The high time resolution enables highspeed simulations. The fast sequence program can contain up to 1024 steps, which are executed at even intervals.

Remote sensing function

The remote sensing function compensates for voltage drops in load lines. It is used to set resistance and voltage values correctly and to make accurate voltage and power measurements. Particularly, the function improves the transitional characteristics in constant voltage, constant power and constant resistance modes, leading to stable operation. (The maximum voltage that can be compensated for is 2 V for one way.)

Switching function

In constant current and constant resistance modes, switching operations can be performed at up to 20 kHz. The switching setting parameters such as the switching level, switching frequency, and duty factor can be changed even while the load is on.

Conguration setting

This function conﬁgures the settings related to the system operation, communication environment, etc. These settings are stored in the system memory, and called when the power is turned on.

• Number of parallel operated load units and master/slave settings

• Load on/off operation at power-up

• Key lock on/off operation at power-up

• GPIB, RS-232C, and USB selection

• GPIB address

• RS-232C communication speed

• Operation mode in which the external reference voltage input is used

• Polarity of load on external control (low/high)

Three memories A, B, and C are provided for each range in each mode, and the set values can be saved. The stored set values can be called freely even while the load is on and saved again. In constant current + constant voltage and constant resistance + constant voltage modes, the constant current and constant voltage memories and the constant resistance and constant voltage memories can be called and saved, respectively.

Setup memories

Up to 100 of the set values listed below can be saved in the setup memories.

• Operation mode (CC, CR, CV, and CP/+CV)

• Current, resistance, voltage, and power values recorded when saved

• Range setting

• Slew rate

• Switching frequency, duty factor, level, and time

• protection settings

• ABC preset memory data

Diverse protection functions

The system features the following protection functions - over current protection (OCP), over power protection (OPP), over voltage protection (OVP), under voltage protection (UVP), over heat protection (OHP), and reverse connection detection (REV). Also available is the alarm input detection function, which turns off the load in response to the input of the external TTL signal.

Sample program

Response speed setting

This system operates by monitoring the input current and voltage values and exerting negative feedback control over those values. You can set the response speed of this negative feedback control as shown below. This function is available in constant current mode (constant current + constant voltage mode) and constant resistance mode (constant resistance + constant voltage mode). If the system operation is unstable or problematic in some other way because of the length of the load line or the size of the loop, you can stabilize the operation by setting the response speed to a lower value.

1/1 : Normal response speed 1/2 : Twice slower than the normal speed 1/5 : Five times slower than the normal speed 1/10 : 10 times slower than the normal speed

Free sample programs for the PLZ-4W Series are available from our web site (www.kikusui.co.jp). These downloadable sample programs include the utility software (MEMcopy) that lets you read and save setup memory data in a ﬂoppy disk or other type of medium, sequence editing software (StepEdit), and VisualBasic applications for measurement data collection and GUI remote control and their source code (VB samples). Install these software programs and the USB driver to a Windows-running personal computer equipped with a USB port (the system is compatible with Windows 98 and later). Then, connect the PC to the PLZ-4W Series electronic load system using a USB cable, and you can readily get started with measurements.

*1 The minimum operating voltage

(including the voltage drop due to the wire inductance component) in switching mode increases by 0.15 V per 1 A/μs at slew rate settings greater than 5 A/μs.

*2 The minimum operating voltage

(including the voltage drop due to the wire inductance component) in switching mode increases by 0.3 V per 1 A/μs at slew rate settings greater than 5 A/μs.

*3 Minimum voltage at which the

current starts flowing to the PLZ-4W. (The PLZ-4W detects no signal at an input voltage less than or equal to approximately

0.3 V and an input current less than or equal to approximately 1 % of the range rating. Therefore,

if the input voltage is gradually increased from 0 V, no current will ﬂow until 0.3 V is exceeded. Once a current greater than or equal to 1 % of the range rating starts flowing, the current can ﬂow at voltages less than equal to 0.3 V.)
