Series PLZ-W Electronic Loads can be operated in constant resistance mode, constant current mode and switching action electronically, replacing the conventional sliding resistors (rheostats). Major features of the PLZ-W series are as follows: 1. Digital Meters. A digital voltmeter and an ammeter with an auto range of 3 1/2 digits. 2. A 1O-Turn Multi-Dial. Current values and resistance values may be set very precisely with the 10 turn multi-dial having a lock mechanism. 3. Function of Presetting. Current and resistance values may be preset. A. Built-in Oscillator for Switching Action. To be used in the constant current mode. Switching action occurs within the frequency range of 10 Hz - 1 kHz. 5. Display of Loading Power. Supplied power value is displayed in a digital figure and in the form of luminescent bar graph. 6. Remote Control Functions. When operated in the constant current mode the instrument may be remotely controlled by either an external voltage or an external resistance. The instrument may also be remotely controlled by an external resistance when operated in the constant resistance mode. 7. One-controlled Parallel Operation. It is possible to increase current capabilities by operating a number of units connected in parallel simultaneously under the control of a master unit. 8. Protection Circuits Include: Overvoltage, overcurrent, overpower, overheating, and input terminal connection in reverse polarity. The PLZ series is offered as a portable desk-top unit and may be integrated into a 19 inch or 500 mm Kikusui standard rack, with the use of the option brackets» 1-2.
