Haier Smart Cube Electricity Meter HMT-CT300A 3-phase power sensor incl. current transformer CT

The Haier 3-phase electricity meter (MPN: HMT-CT300A) operates with a maximum operating current of 300A. With high-precision 1% power measurement, you have complete control over your electricity consumption and can save energy and reduce costs in a targeted manner. Thanks to bidirectional measurement, you always have an overview of both import and export flows. The real-time data update rate of 100ms and two pulse outputs provide you with immediately actionable insights. In addition, the RS485 output allows you to conveniently view the data remotely on another display or computer. With a user-friendly LCD display, the Smart Meter can be easily integrated into your system.

How it works

The electricity meter is your reliable partner for the precise measurement and display of three-phase three-wire networks (3p3w) and three-phase four-wire networks (3p4w). It records key parameters such as voltage, frequency, current, power, and active and reactive power, both in import and export. Energy is measured in kWh and kVArh (unit of measurement for reactive energy), giving you a transparent and comprehensive overview. The device also allows the maximum demand current to be recorded over preset time periods of up to 60 minutes. For a correct energy balance, the power sensor requires voltage and current inputs in addition to the power supply, which are provided by the included current transformers (CTs). This ensures that your energy consumption data is always recorded reliably and accurately.
