About Power Meter EPM 7000
EPM 7000 power meters are conceptualized and intelligent to revolutionize the approach to traditional power metering. Each power meter is a compact, electronically advanced and programmable multi-display metering device (MDMD). It is the answer to future generation of electrical metering needs and methodology.

Environmental Impact & Cost Saving
A power meter can replace many units of conventional analog or digital instruments and change over switches (e.g. Amp, Volt, KVA, KW, PF, KWH, KVarH, FQ etc.). This saves on the wiring material usage and reduces the cost on metering needs. With the power meter modern and practical MDMD, the front layout of switch boards and control panels are aesthetically refined.

Increase Productivity & Efficiency
The power meters are specifically designed to be compatible with the world's 2 most widely used DIN standard panel instruments (It fits the DIN 92 * 92 mm panel cutout holes). The power meter as a MDMD greatly reduced cabling complexity and time. It is also a standardize hardware suitable for either 1 phase 2 wires, 1 phase 3 wires, 3 phase 3 wire or 3 phase 4 wires networks.

Improved Technical Superiority and Reliability
The power meters are endowed with technical specifications, (overload capabilities, accuracy levels, long term stability, readout dependability etc.) far exceeding those of conventional instruments. To overcome the critiques of digital metering, the power meter MDMD supports a LCD screen with alphanumeric readouts. The multidisplay readings can be "damped" through it readout resolution besides the option to manually or automatically prioritize and sequentially view the more than 30 electrical parameters. To meet future metering environments, the power meter is equipped with a serial port (RS-485 or RS-232), to allow connection to an open architecture computerized network. Running on PC or data acquisition system and complying with Modbus(R) protocol. The software provides a simple yet practical solution to energy management in factories and plant, small industries, building services, etc.

Parameter Conversion
The microprocessor-based power meter now provides compatibility with the modicon Modbus(R) system as a standard featured. From the LCD multi-display reading V, A, VA, W, Var, WH, etc. more than 30 power and energy parameters.
