Features

In addition to basic constant current, constant resistance, constant voltage, and constant power modes, the PLZ-5W Series offers a variety of other functions. The PLZ-5W series also provides better performance than previous models.

High-speed response

The rise time has been improved from 10 µs to 5 µs.

Expanded voltage range

The minimum operating voltage has been improved from 1.5 V to 1.0 V, offering support of low voltage input.

Arbitrary I-V characteristics mode

Arbitrary I-V characteristics mode that allows current to be set arbitrarily in relation to voltage input. This mode can be used for simulation of LED loads and the like.

Color liquid crystal display (LCD)

Allows easy-to-see display in color. The voltage value, current value, power value, current capacity value (Ah), and power capacity value (Wh) at the load input terminal are indicated on the display.

Increased power capacity and current capacity

Power capacity and current capacity 1.2 times those of previous models have been realized while keeping the size unchanged.

Larger capacity achievable

Larger capacity can be achieved by connecting optional boosters (PLZ2405WB) to the PLZ1205W. Up to four booster units can be operated in parallel using a PLZ1205W unit as the master unit (up to 10.8 kW, 2160 A).

Support of synchronized operation

Load on/off control and the execution of sequences can be synchronized for multiple PLZ-5W units.

Installation and Preparation

WARNING

Connect to a properly grounded outlet.

Connecting the Power Cord

Risk of electric shock.

• The PLZ-5W conforms to IEC Safety Class I (equipment that has a protective conductor terminal). Be sure to earth ground the product to prevent electric shock.

• The PLZ-5W is grounded through the power cord ground wire. Connect the protective conductor terminal to earth ground.

• Use the included power cord to connect to the AC line. If the supplied power cord cannot be used because the rated voltage or the plug shape is incompatible, have a qualified engineer replace it with an appropriate power cord that is 3 m or less in length. If obtaining a power cord is difficult, contact your Kikusui agent or distributor.

• The power cord with a plug can be used to disconnect the PLZ-5W from the AC power line in an emergency.

• Secure adequate space around the power cord plug. Do not insert the power cord plug into an outlet that is difficult to access or place objects around the power cord plug that will make plugging and unplugging difficult.

• Do not use the supplied power cord with other instruments.

The PLZ-5W conforms to IEC Overvoltage Category II (energy-consuming equipment that is supplied from a fixed installation).

Turn the POWER switch off ( ).

Check that the AC power line meets the nominal input rating of the PLZ-5W.

The PLZ-5W can receive a nominal line voltage in the range of 100 Vac to 240 Vac at 50 Hz or 60 Hz. (Frequency range: 47 Hz to 63 Hz)

Connect the power cord to the AC INPUT inlet on the rear panel.

Connect the power cord plug to a properly grounded outlet.

This completes the setting.

12 User’s Manual PLZ-5W

Installation and Preparation

POWER switch

CAUTION

Checking Whether the Power Is On or Off

Turning the power on

Check that the power cord is connected correctly.

Check that nothing is connected to the DC INPUT (load input) terminals on the front

and rear panels.

Turn the POWER switch on ( ).

The PLZ-5W turns on, and the display lights.

If you notice strange sounds, unusual odors, fire, or smoke around or from inside the PLZ-5W, turn the POWER switch off, or remove the power cord plug from the outlet.

By factory default, the panel settings immediately before the POWER switch is turned off are saved. When you turn the power on, the PLZ-5W starts in the same state as it was in the last time it was turned off. (However, the load setting is always Load Off.)

The panel setting state at startup can be changed (p.112).

Turning the power off

Press the ( ) side of the POWER switch to turn the power off.

If you want to turn the POWER switch back on, wait at least 5 seconds after the fan stops. Repeatedly turning the POWER switch on and off at short intervals will shorten the service life of the POWER switch and the internal input fuse.

PLZ-5W User’s Manual 13

Installation and Preparation

WARNING

CAUTION

Connecting to the DUT

The PLZ-5W has load input terminals on both its front and rear panels. The specifications of the PLZ-5W are for the load input terminals on the rear panel.

For information on selecting load cables, refer to “Selecting the Load Cables” (p.141) in the “Appendix”. Large current load cables are available as options. For details, see the Large Current Load Cable Manual in the included CD-ROM.

Risk of electric shock.

• Do not touch load input terminals when the output is turned on.

• The load input terminals on the front panel are connected internally to the load input terminals on the rear panel. The voltage applied to the terminal on one side appears directly at the terminal on the other side.

Risk of damage.

• Do not connect the DUT to the load input terminals while the product’s load is turned on.

• Do not connect electronic loads to the load input terminals on the front panel and those on the rear panel at the same time.

• Do not invert the polarity when connecting. An overcurrent might flow when the load is turned on.

To avoid overheating, observe the following precaution.

• Use the supplied screws to connect the cables with crimping terminals.

Connecting to the load input terminals on the rear panel

Connect the DUT to the load input terminals on the rear panel.

Risk of electric shock.

• Be sure to attach the cover for the load input terminals on the rear panel.

• Attach the protection plate or cover for the load input terminals on the front panel also to the load input terminals on the front panel. The voltage applied to the load input terminals on the rear panel appears at the load input terminals on the front panel.

Turn the load off.

Turn off the output of the DUT.

Attach crimping terminals to the load cables.

The load input terminals on the rear panel have bolt (M10) holes for connecting the load cables. Attach the appropriate crimping terminals to the cables.

Connect the load cables to the load input terminals on the rear panel using the

included load input terminal screw set.

To prevent interference with the cover for the load input terminals on the rear panel, basically connect the crimping terminals in orientation (1) in the figure. If the crimping terminals are small and cannot be connected in orientation (1), connect them in orientation.

Connecting to the load input terminals on the front panel

The load input terminals on the front panel enable you to easily connect the DUT to the PLZ-5W. The specifications of the PLZ-5W are for the load input terminals on the rear panel. The load input terminals on the front panel may not meet the specifications.

Risk of electric shock.

• Attach insulation caps to the crimping terminals.

• When not using the load input terminals on the front panel, be sure to attach the cover for the load input terminals on the front panel or the protection plate.

• Attach the cover for the load input terminals on the rear panel also to the load input terminals on the rear panel. The voltage applied to the load input terminals on the front panel appears at the load input terminals on the rear panel.

The rated current value of the load input terminals on the front panel of the PLZ1205W is 80 A. When a current of 80 A or more flows to the load input terminals on the front panel, an alarm occurs and the load turns off.

Turn the POWER switch off.

Notes regarding load input terminals

Do not apply overvoltage to the load input terminals

Risk of damage. Do not apply a voltage that exceeds 150 Vdc to the load input terminals.

When an overvoltage of 165 V is applied when the voltage range is 150 V, or when an overvoltage of 16.5 V is applied when the voltage range is 15 V, a beeping sound is emitted and an alarm appears. If this happens, immediately lower the voltage of the DUT.

Match the wiring polarity with that of the DUT

Be careful to match the polarities of the load input terminals with those of the DUT during connection.

If a reverse voltage of 0.6 V or higher is applied, or a reverse current (approximately -1 % of the range rating) flows, a beeping sound is emitted and an alarm appears. If this happens, immediately turn off the POWER switch of the DUT.

Remote Sensing

You can change a voltage measurement point from a load input terminal to an arbitrary sensing point. By setting sensing points at the DUT end, influences such as voltage drops caused by the resistance of the load cables can be reduced, and the load current can be stabilized.

To use remote sensing, connect the sensing cables to the sensing terminals of the PLZ-5W and the DUT end, and enable the remote sensing function.

Connecting the sensing cables

• Risk of damage to the internal circuitry. Never wire the sensing terminals while the POWER switch is turned on.

• If the remote sensing cables come loose while remote sensing is in use, the PLZ-5W and DUT may be damaged. Be sure to connect the cables securely.

Unlike the load cables, there is no need to consider the current capacity for the sensing cables. However,

for adequate mechanical strength, use wires whose nominal cross-sectional area is 0.5 mm

Constant current (CC), constant resistance (CR), and constant power (CP) control

You can control the load values (current, conductance, power) of CC, CR, and CP modes using external voltage. When you apply an external voltage between 0 V to 10 V to the EXT CONT connector, a load setting proportional to the change can be obtained.

An external voltage of 0 V results in a load value that is 0 % of the range rating, and an external voltage of 10 V in a load value that is 100 % of the range rating. The accuracy cannot be guaranteed when the external voltage is less than 0 V or more than 10 V.

To avoid damaging the product, observe the following precautions.

• The maximum voltage that can be applied across pins 21 and 23 of the EXT CONT connector is ±11 V. Do not apply a voltage that exceeds this.

• Pin 23 of the EXT CONT connector is connected to the negative (-) load input terminal. Make sure that the wire of pin 23 does not touch any of the other pins.

Turn the POWER switch off.

Connect an external voltage across pins 21 and 23 of the EXT CONT connector.

To prevent noise interference, use twisted wires for the signal cables. Use a highly stable external voltage that has low noise.

Turn the POWER switch on and check that the load is off.

Controlling the current to be superimposed on the constant current (CC)

You can control the current to be superimposed to the current value of CC mode with an external voltage.

When you apply an external voltage between 0 V to 10 V to the EXT CONT connector, the load current becomes the sum of the current proportional to the external voltage change and the Present current setting. When you apply an external voltage between -10 V to 0 V to the EXT CONT connector, the load current is equal to the current that is proportional to the external voltage change subtracted from the present current setting.

The current that is added to the current setting for an external voltage of 0 V is 0 A. The current that is added to the current setting for an external voltage of ±10 V is 100 % of the rating. However, the final load current range is 0 A to 100 % of the range rating.

To avoid damaging the product, observe the following precautions.

• Do not apply a voltage outside ±11 V across pins 19 and 20 of the EXT CONT connector.
