The PM135 is a multi-functional three-phase power meter with basic revenue metering, power quality and harmonics analysis. The PM135 provides a cost-effective substitute for numerous analog meters used by industrial, commercial and utility customers for basic power metering. The PM135 is widely integrated in panel boards and SCADA systems. With the addition of the unique TOU module, the EH model answers the needs of revenue metering applications. It is also suitable for utility substation automation with its support of the industry standard DNP 3.0, Modbus RTU and IEC 60870-5101/104 protocols, as well as its I/O capabilities (using the Digital Input/Output modules). The PM135 series consists of two basic models providing digital measurements of more than 80 electrical parameters locally, and more than 100 electrical parameters via RS-485 interface. The PM135 has a 3x2” / 76x49mm backlit LCD display as well as SATEC's unique bar graph loading indicator. Measurement & Communication The PM135 accurately measures over 100 parameters from basic frequency, voltages and currents, to all power parameters, four quadrant active, reactive and apparent energies, harmonics and time of use (TOU). Measurement Features The PM135 has an integral RS-485 communication port for a wide range of protocols—Modbus, DNP 3.0 and IEC 60870. Its expansion module allows connection of a second communication port, including Ethernet, Profibus, RF or GPRS, as well as second RS-485 and RS-232 ports.
