PZ7777 single phase Voltmeter
Function: Measure and display the voltage value in the electrical circuit with digital direct reading method. The meter can be used as normal digital Voltmeter, it can also be used as voltage transmitter with the function of displaying one measuring value by installing the analog input module. It can be used as current/voltage data collector, for protecting over-limit alarm of normal voltage and multi-functional network electric meter, which has measuring, alarming, transmitting, communicating, etc.

PZ7777 three phase Voltmeter
Function: Measure and display 3 currents (or voltage) in the electrical circuit with digital direct reading method. When providing real-time measurement and indicating function, the meter also has analog transmission\upper and lower limit alarm\RS485 communication each function separately by adopting different function modules. There are total 5 output methods, including 3-way transmitting simultaneous output\3-way alarm contact(3 relays) simultaneous output\3-way alarm one relay output\RS485 communication output\3-way alarm one relay output+RS485 communication output(note: 48× 48 square meter has no output function at present).

There are programmable keys on the panel, which can program and set parameters including transformer rate\upper and lower limit alarm value\communication address of the meter\communication baud rate\transmitting output method\transmitting output range, etc. Parameters.

AC: Voltage 100V\660V optional, other specification can be made by users
DC: Voltage 75mV\660V optional, other specification can be made by users
