TH3600 Broadband Low Current Standard Power Source

Model: TH3600
Brand: TUNKIA

Product Description

1.Summary

TH3600 is a three-phase standard power source with wide frequency and low current output. The output bandwidth is 45 Hz~1kHz, and the low current output can be as low as 20μA. It can be used as a power/energy calibration source for high-precision current measurement and analysis below 120mA. It makes up for the serious shortcomings of traditional electric energy meter calibration devices in broadband and low current measurement. It has optional power accuracy of class 0.005 and 0.01.

2.Features

• Maximum output: 528 V / 120 mA, which can ensure the stability of value output under full load conditions.

• Minimum current output: as low as 20μA.

• Multi-functional electric energy measurement: It has forward, reverse active and reactive energy, and supports the calibration of electric energy meters.

• Harmonic function (optional): Can load 2nd to 63rd harmonics with adjustable amplitude and phase to complete the harmonic impact test.
