GF3031 500V 120A Portable Three Phase Electrical Power Calibrator

Three Phase Electrical Power Calibrator

The GF3031programmable electrical power calibrator is a powerful and high precision 0.05% portable three phase current and voltage source. All test values are generated absolutely synthetically with a high degree of accuracy and stability. The source is available in 6A, 12A, 20A or 120A version. Voltage and current phase shift can be adjusted from 0.000° to 360.000°, stability 0.01%/min.
The GF3031 three phase portable power calibrator is a lightweight and portable current and voltage source based on newest technology and serves for solving this problem by simulating the required load conditions. Operation is performed by integrated 7" touch screen or via keyboards. It is a high precision test equipment as AMI R & D or energy meter manufacturer factory. This model three phase power calibrator can test energy meter, power meter, ammeter, voltmeter, phase angle meter, power factor meter & frequency meter etc.
