ELECTRONIC LOAD
Information
Model PLZ1002W Electronic Load is rated for loading voltage
3 - 110 volts, loading current 0 - 200 amperes, and wattage
1000 watts. The PLZ1002W can be operated either in a
constant current mode or in a constant resistance mode.
The PLZ1002W allows dynamic load test by switching between
two different levels of load current with its internal
Oscillator and electronic switching circuit. This function
is available when in either the constant current or
resistance mode.
The PLZ1002W is incorporated with protectors against
overvoltage, overcurrent, overpower, and reverse polarity
connection. It has a digital voltmeter/ammeter of 3-1/2
digits. It has a fan for forced air cooling.
Features
(1) The PLZ10Ö2W employs power MOS FET, thereby eliminating
secondary breakdown and improving the reliability.
(2) A digital voltmeter/ammeter of 3-1/2 digits is provided.
(3) Two 10-turn helical potentiometers are provided to set
individual levels of loading current.
(4) The loading current can be switched between two
different levels, thereby allowing dynamic load test.
(5) The loading current can be remote-controlled with a
voltage signal (when in the constant current mode) or with a
resistance signal (when in the constant current or
resistance mode).
(6) Two or more units or PLZ1002W can be operated in
parallel in a master-slave mode.
(7) The PLZ1002W is incorporated with protectors against
overvoltage, overcurrent, overpower, overheat, and inverted
connections of input. These protectors reset automatically,
(8) The PLZI002W is incorporated with a rapid-response rush
current suppression circuit.
(9) Optional frames and brackets are available to install
the PLZ1002W on a rack of the EIA Standard or the JIS Standard.
