상세사양

A high accuracy AC and DC power calibrator suitable for calibrating single-phase watt-meters, power meters, and kW-Hr meters.

The 5077 is a practical solution to precision power simulation, providing a simultaneous supply of voltage and current with phase control.

The unit is operated via a virtual control software application allowing the user full control via laptop or PC.

The 5077 voltage range is 20 mV to 1050 V, with current from 20 mA to 22 A.

Frequency can be set in 0.01 Hz steps from 40 to 400 Hz, and phase in 0.1° steps. Alternatively power factor (PF) can be set in steps of 0.01.

The output can be displayed as VA or Watts. The wide current and voltage ranges enable verification of power meters on either the primary side of the of the CT / VT or directly connected to the meter (secondary side).

The standard maximum AC current output (22 A) can be extended to 100 A by using an optional 100 A current transformer.

This extends the maximum power to 0.1 MW/MVA.  A single and 50-turn current clamp adaptor is available for clamp sensor and meter calibration up to 1100 A.
