PD666-S4 series three phase digital multi-functional meter

Summary&application:

PD666-S4 series three phase digital multi-functional meter is designed for the demand of power monitoring and electric energy measurement including power system, communication industry and construction industry, mainly applied into real-time measurement and indication for the electrical parameters such as three phase voltage, three phase current, active power, negative power, frequency, power factor and energy in the electrical circuit, realizing networked through RS485 communication interface and external device for remote data transmission, which is widely used into variety of intelligent power distribution system for power monitoring and industrial automation, etc.


1. Main functions and characteristics:
◆ It can measure  three phase current, three phase voltage, active power, reactive power, power  factor, frequency, positive/negative active energy and four-quadrant reactive  energy.
◆With the standard RS-485 communication interface, it  adopts the standard ModBus-RTU communication protocol and the baud rate can be  set.

◆Parameters such as current/voltage ratio, type of  network, communication address of the meter, communication baud rate, etc. are  programmable.
