Haier Smart Cube electricity meter HMT-CT300A 3-phase power sensor incl. CT accessories

The 3-phase electricity meter from Haier (MPN: HMT-CT300A) works with a maximum operating current of 300A. With high-precision 1% power metering, you have complete control over your electricity consumption and can save energy and reduce costs. Thanks to bidirectional measurement, you always have an overview of both import and export currents. The real-time data update rate of 100 ms and two pulse outputs provide you with immediately usable insights. In addition, thanks to the RS485 output, you can easily 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 as well as active and reactive power, both in import and export. The energy is measured in kWh and kVArh (unit of measurement for reactive energy), giving you a transparent and comprehensive overview. The device also allows you to record the maximum demand current over preset 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 via the enclosed current transformers (CTs). So you can be sure that your energy consumption data is always recorded reliably and accurately.
