The PLZ1002W is a 1000 W Electronic Load rated for up to 110 volts and currents to 200 amperes. It can be operated either in a constant current mode or in a constant resistance mode. The PLZ1002W allows dynamic load testing by switching between two different levels of load current with its internal oscillator and switching circuit. The PLZ1002W offers worry-free operation with protection against overvoltage, overcurrent, overpower, and reverse polarity connection. It has a 3.5 digit voltmeter/ammeter and is fan-cooled.
