Chapter 1: General

1.1 General

The PLZ-3WH series electronic load unit is a multifunctional system designed to offer the highest levels of safety and reliability. This load unit contains a high-performance current control circuit to ensure stable, high-speed operating performance. In addition, its CPU control feature works to improve operability and multifunctional capability. The unit's constant power-control feature allows you to, for example, test batteries more efficiently. Moreover, when various optional interfaces or a dedicated remote controller are employed, the load unit can be incorporated into a wide-ranging test and inspection system. This PLZ-3WH load unit also permits various high-speed load simulations to be conducted.

1.2 Feature

The PLZ-3WH series electronic load unit offers a wide array of features. This section describes some of the more notable ones.

■ Constant power mode

The load unit supports a constant power-mode control feature which is highly effective in battery life tests. Constant current, constant resistance, and constant voltage modes are also available.

■ 50

µµ

µs high-speed operation

µµ

Constant current mode provides rise and fall times as short as 50 µs, thereby allowing you to conduct more accurate DC power transient response tests and to generate simulated waveforms for use as dummy loads.

■ Sequence function

With PLZ-3WH units, arbitrarily set sequence patterns can be saved to built-in memory. Two types of sequences are available: a fast speed sequence programmable at 100 µs a step; and a normal speed sequence allowing ramp waveforms to be set for every step. The saved sequence patterns can be executed using either a host controller or trigger signal from a PC (via an interface), or from the operation panel of the load unit.

■ Operability

Major functions of the load unit can be promptly triggered, due to the unit's "one key - one function" design philosophy. Highly precise settings can be easily input using the jog-shuttle or optional numeric-key unit. The optional remote controller ensures remote control capability. And for repetitive tests, there are two highly convenient functions: a setup function, helpful in saving and calling set items; and a dedicated-key operating function, which allows operating mode settings to be easily saved and retrieved.

■ User-friendly backlit liquid crystal display

Since this load unit is equipped with an LED-backlit liquid crystal display (LCD), operating instructions and test data are easily viewed and monitored regardless of surrounding lighting conditions.

■ Abundant interface boards (optional)

These optional interface boards support various control methods allowing a variety of functional systems to be developed in combination with the unit's sequence functions. When our unique MCB extension serial interface is used, for example, up to fifteen devices (electronic load units and/or power supplies) can be controlled on-line from a single general-purpose interface.
