Three-phase electricity meter, CT 1-5A 4M, pulse output, MID ECP300C

Three-phase energy meter with pulse output

This advanced energy meter, designed for three-phase systems, offers precise measurement of active and reactive energy consumption. The ECP300C model features a compact design (4 module width) and the ability to be mounted on a DIN rail, making it easy to integrate with existing electrical infrastructure. A current transformer in the range of 1-5A makes the meter ideal for use in commercial and industrial buildings where various loads occur.

The meter complies with the MID (Measuring Instruments Directive), which guarantees its legalization and measurement reliability. Equipped with an S0 pulse output, it enables remote data reading and integration with energy consumption monitoring systems. This allows both installers and end-users to effectively manage energy and optimize costs.

Functionality and application

ECP300C is not only a measuring device, but also a tool for analyzing energy consumption. Dual tariff allows for billing energy consumption in different time zones, which is particularly useful in facilities with a dynamic load profile. Anti-tamper protection ensures security and protects against unauthorized manipulation.

The meter is used in:

• Commercial buildings: offices, shops, shopping centers – precise measurement of energy consumption allows for optimization of operating costs.
• Industrial facilities: production plants, workshops – monitoring energy consumption in individual production processes enables identification of areas requiring improvement in energy efficiency.
• Multi-family residential buildings: housing associations – fair billing of energy consumption between individual premises.
• Photovoltaic systems: measurement of surplus energy fed into the grid.

Specification and design features

The ECP300C meter is characterized by a solid construction and high accuracy class (B). Its compact dimensions (72 mm width, 90 mm height, 60 mm depth) allow for easy installation even in limited space. The rated voltage range (92-276 V N-L and 160-480 V L-L) and frequency (45-65 Hz) ensure compatibility with various electrical systems.

The pulse output generates from 1 to 10000 pulses per kWh (or kvarh), allowing flexible adaptation to the requirements of various remote data reading systems. The protection degree IP20 provides protection against accidental contact and contamination. Additionally, the ability to control tariffs externally gives full control over the billing process.
