Multifunctional Power Meter with LCD Display

Description

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 TCP/RTU and IEC 60870-5-101/104 protocols, as well as its I/O capabilities (using the Digital Input/Output modules).

The PM135 has a 3" × 2" (76mm × 49mm) backlit LCD display as well as SATEC's unique LED bar graph loading indicator.

Measurement and 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).

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/RS-232 port.
