1, the pressure regulating accuracy < plus or minus 1%
2, jumper copper choose vac detected voltage single-phase 120/240
3, to the jumper copper choose 50/60 Hz
4, loss of detecting voltage protection circuit
5, with a low frequency protection (UFRO) and low voltage function is established
6, the LED indicator low frequency condition
7, can with jumper copper set to match the different power generators
8, prominent features: stable circuit provides adjustable exchange negative feedback, to suppress components include sub cycle peak voltage failure AVR components and reduce a lot of noise in the generator terminal.
9, selling point: low pass filter to prevent the distortion of waveform AVR affecting operation
