The PM135 is a multifunctional three-phase power meter with basic revenue metering, power quality and harmonics analysis. (It) 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 60870-5-101/104 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.
