PS7777-□ series digital active/reactive power meter
< >
Summary & Application: PS7777-□ series digital active power meter is the new generation of programmable intelligent instrument, integrated with measurement, alarming, transmission and communication, mainly applied into real-time measurement and indication for the active power in the three phase electrical circuit, conducting limited alarming output for transmission output towards electrical data according to the set measured value, realizing networking through RS485 communication interface and the host computer.
◆It can measure and display single/three phase active power value with digital direct reading method.
◆Extendible for analog quantity output function, transmitting specification of 4~20mA, 0~20mA, 0~10mA which is optional.
◆Extendible for switch quantity output function for the relay, realizing upper/lower-limit alarming output.
◆Extendible for RS-485 communication interface, adopting the standard ModBus-RTU communication protocol and the baud rate can be set.
◆Parameters including current/voltage ratio of the meter, upper/lower-limit alarm value, alarming return difference, communication address of the meter, baud rate, transmitting output mode, transmitting output range, etc. are programmable.
