XF1a Type Three phase AC Instrument Calibration DeviceDetailed product description：

Compared with similar products, the XF1a three-phase AC instrument calibration device has higher waveform output stability and smaller distortion.
Fast output, accurate and reliable protection against voltage short circuits and current open circuits.
Single phase output power is high, with each phase outputting up to 30W.
More powerful harmonic output capability, capable of generating 2-31 harmonics, with a maximum harmonic amplitude of up to 50%.
The unique integrated design of the table source is both a standard source and a standard table. When the source is closed, it automatically switches to the standard table state, and you can use it as a standard table. The table source switch is fully automatic. At the same time, it can also measure the input of the clamp gauge.
The three-phase voltage and current phase can be set or adjusted arbitrarily.
High quality 6.5-inch true color LCD screen, wide temperature range, wide field of view, high brightness, can be used indoors or outdoors clearly and clearly.
