MKR 48AC CURRENT (POWER) TEST SIMULATOR

Product catalog summary

Overview:
The MKR 48AC Current (Power) Test Simulator is a portable device designed for field testing and calibration of single and three-phase protective devices and AC current transducers. It can also be used for verifying the calibration of wattmeters and transducers for active and reactive power.

Specifications:

Supply Voltage: 110 or 230V, 40-70Hz
Output Current: Up to 12A continuously, up to 25A for 60 seconds, above 25A for 30 seconds
System Voltage: Maximum 725VAC
Fuses: 630mA (20mm)
Weight: 4.7 kg
Dimensions: 235x300x130 mm (HxWxD)

Key Features:

Galvanically isolated current output from mains input
Adjustable single-phase current source
Two-pole mains switch with a red signal lamp
Accessible fuseholder with a spare fuse

Usage Instructions:

Connect the current loop to the CURRENT OUTPUT terminals.
Adjust the output current using the CURRENT ADJUST knob.
Ensure minimal ohmic resistance in external wiring for high current levels.
For testing watt-transducers, connect supply voltage with correct phase sequence.
Inject current output in the specified phase for calibration of watt-transducers.

Testing Configurations:

Single-phase (1W1)
Three-phase, 3-wire symmetrical load (1W3)
Three-phase, 3-wire asymmetrical load (2W3)
Three-phase, 4-wire asymmetrical load (3W4)

Important Notes:

Direction of current flow must be as specified for reverse power simulation.
Each wattmeter-element in multi-element transducers must be measured individually.
