Operating voltage: no need to connect to any power supply, two-wire system.
The two-wire voltage meter design, the wiring is simple, easy to install.
When there is a slight error, you can calibrate it through the circuit board, "fine-tuning" potentiometer for calibration.
Power supply range: No additional power supply needed, direct use of the measured voltage as a power supply, range: AC70V-500V.
Maximum input: AC500V. Note: Input voltage higher than 500V may be permanently damaged!
