•Serial number (indicated at the lower section on the rear panel)
1.2 Product Overview
The PCZ1000A is an AC electronic load featuring high reliability and safety. In
addition to the resistive loads generally used in tests, it is capable of simulating
capacitive-input rectifier loads.
1.3 Features
●Crest-factor function
In addition to the constant-current*, constant-resistance*, and constant-power*
modes, the PCZ1000A also features a crest-factor function which is useful for
load testing of peak or harmonic currents. This helps reduce design and labor
time and cost as well as improve the quality of the equipment under test.
* The instrument always allows a current waveform close to a sine waveform to
flow unaffected by the voltage waveform.
●Simple operation
The key features can be operated quickly on a one-key-to-one-feature basis. Fine
adjustment is possible with the rotary knob.
●Easy-to-see LCD with backlight
The instrument features an LCD with LED backlight, enabling a variety of
operations to be performed. Test results are displayed clearly and are unaffected
by ambient light.
●Parallel operation
Up to five units can be used in parallel under the control of a single master unit. A
PCZ1000A can be set as a master and up to four slave PCZ1000As connected in
parallel (max. 5 kW, 50 Arms). The total power is displayed on the front panel of
the master unit.

General Description
●Tracking operation
Up to five units can be tracked
Setup values specified on the master unit are also applied to the slave units and
any changes to the master unit settings are also applied immediately to the
slaves. Useful for testing single-phase/three-wire or three-phase/three-wire AC
power supply loads.
