GF3031 120A 600V variable portable three phase electrical power calibrator for energy meter manufacturer
The GF3031 is a powerful and 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 12 A, 24A or 120 A.
The GF3031 three phase portable power source 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.
The GF3031 will supply pure sinusoidal voltage to 600 V and current to 120 Amps. Up to 200 VA's of power are available from the voltage terminals to support instruments which draw power from the line on which they are measuring, or where the voltage circuits of several devices are connected in parallel. Up to 1 V peak compliance is available from the current output to ensure current is delivered in setups involving long cable runs, connectors and switches, or where the current circuits of multiple instruments are connected in series. The current output is also able to produce an auxiliary voltage in order to simulate signals that may be produced by transducers or current probes. Higher ac current outputs are available from the 100A and 200A options.
