PA7777 PZ7777 measure and display 3 currents (or voltage) in the electrical circuit with digital direct reading method. Only one 3-phase digital Ammeter can finish the measuring task of A phase current、B phase current、C phase current, which can only be done by three normal Ammeter. At the same time, one 3-phase digital Voltmeter can finish the measuring task of A phase voltage、B phase voltage、C phase voltage, or AB phase line voltage、BC phase line voltage、AC phase line voltage which can only be done by three normal voltage. 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.
