TD3900 High-precision Three-phase Power Source

（This diagram is for reference only; actual delivery may vary.）

1. Summary

TD3900 is a high-level, highly stable three-phase power source consisting of a precision three-phase power source, control console, computer, and specialized software.

The three-phase power/electric energy output accuracy level of the device is Class 0.02, and the short-term stability of power/electric energy output reaches 30ppm/2min (I≥20mA).

TD3900 can be combined with the TH33 series three-phase multi-function standard meter to form a Class 0.005 standard energy meter calibration device, or it can be used alone as a high-accuracy and high-stability standard three-phase power source.

2. Feature

• Three-phase Power Output: maximum voltage up to 576 V, maximum current up to 120 A. The minimum current output is as low as 0.2 mA, which is the basis for the starting test of the electric energy meter under test.

• High-order Harmonic Output/Measurement: It can output 2 to 127 harmonics with adjustable amplitude/phase to complete the standard harmonic calibration of the energy meter, or to analyze the harmonic content and harmonic distortion of the tested three-phase source.

• Harmonic Output/Measurement: Voltage and current support single or multiple simultaneous application of the 2nd to 127th harmonics, with an amplitude of 0 to 40% and a phase of 0.0° to 359.9° adjustable.

• Comprehensive Power Analysis: The device has waveform display, phasor diagram display, power stability test, trend curve drawing, data statistical analysis, etc.

• Mobile Control Console: The value output can be observed or controlled through its large-size high-definition LCD touch screen, which facilitates manual detection by users.

• Special Software: The software can realize automatic calibration or verification of single/three-phase standard energy meters, single/three-phase standard sources, and automatically generate reports.
