Overview:
The digital three-phase shifter is a portable electrical tester composed of transformer phase shifter, digital phase display, voltage current digital display, output voltage adjustment, coarse adjustment, fine adjustment, and power supply, etc. The digital three-phase shifter combines the transformer phase phase technology with digital measurement techniques, which can be adjusted at any angle in the range of 0 to 360 °, which has high precision, reading. Accurate intuitive, the voltage output is adjustable, the digital three-phase shifter structural components use independent fixtures, firm and reliable, full seals, easy to carry in the field and on-site use.
