Manufacturer:
Kikusui Electronics Corporation
Model: PLZ-300W
Date:
Category: Measurement instruments
Group: Other
Description: ELECTRONIC LOAD
Information:
                                    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 autorange o£ 3
1/2 digits.
2. A 10-Turn Multi-Dial.
Current values and resistance values may be set very
precisely with the 10 turn multi-dial having a lock mechanists.
3. Function of Presetting.
Current and resistance values may be preset.
4. 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.
Constant voltage mode: 5 - 60 V DC
Constant Current Characteristics.
Stability: 0.1% + 6 mA for loading voltage variation from 4
to 60 V
0.1% + 6 mA for line voltage variation by ±10% Ripple and
noise: 5 mA RMS
Temperature coefficient: 0.02%/°C (standard value)
Rise/fall time: 100 ysec or less (when an internally
installed oscillator is used).
Constant Resistance Characteristics.
Stability: ±10% loading voltage variation:
(Stability) (Input Voltage (Setting resistance)
Variation)
4 - 10 V 1 Ω
4 - 40 V 10 Ω
Stability ±10% variation of line voltage: 0.1% + 6 mA
Temperature coefficient: 0.03%/°C standard value (at the
minimum resistance value of a range).
Remote Control.
Constant current: External resistance 0 - 1000 Ω
External voltage 0 - 10 V DC Constant resistance: External
resistance 0 - 1000 Ω Constant voltage: External voltage 0 -
10 V DC
Protecting Functions.
Overvoltage protection: Approx. 65 V DC Overcurrent
protection: Approx. 65 A DC Overpower protection: Approx. 330 W
Wrong polarity input protection: By use of a diode
Overheating protection: 100°C ±5°C at cooling package Line
input fuse rating: 1 A
