HOBUT Electromechanical 3 Phase LCD Energy Meter 92x92mm Cutout, Depth 80mm M850-LTHN-RS-PO

HOBUT M850-LTHN-RS-PO Electromechanical 3 Phase LCD Energy Meter provides detailed and accurate electrical measurements essential for power management and monitoring. The meter supports a voltage measuring range from 28 V to 570 V. Its 96x96 mm moulded case and the 92x92 mm cutout make it suitable for standard panel installations. The large LCD allows users to select from three backlight colours for clear visibility in different lighting conditions.

Designed for industrial, commercial, automation, and building management systems, the meter is user-friendly with four front programming buttons. It supports user-programmable CT and VT ratios to accommodate various installation requirements. The standard configuration is for 3 phase/4-wire systems, but it can also be programmed for other voltage inputs or single phase systems.

The meter measures key electrical parameters such as phase voltage, phase to neutral voltage, phase current, frequency, active power (W), active energy (kWh), reactive power (VAR), apparent power (VA), reactive energy (VARh), and power factor (PF). It also tracks instantaneous and maximum demand values, including neutral current measurements. The integrated pulse output and optional RS485 port facilitate communication using Modbus RTU or BACNET MSTP protocols, enabling integration into energy management and automation systems.

Its programmable features include baud rate selection, parity, stop bits, system type (single or three phase), AC/DC auxiliary voltage, RS485 device addressing, and security code access to protect settings from unauthorized changes. The meter operates reliably within an ambient temperature range of -20°C to 70°C.

Compliance with IEC 1036 Class 1 accuracy, IEC 60947-1, various IEC electromagnetic compatibility standards (61000 series), and safety standard IEC 61010-1 ensures performance and safety in demanding applications. The product is manufactured in the United Kingdom to high-quality standards.

The meter features a 96x96 mm moulded case with a 92x92 mm cutout for panel mounting. Equipped with a large LCD display with selectable backlight colors for easy reading. Supports user-programmable current transformer (CT) and voltage transformer (VT) ratios.

Configured for 3 phase/4-wire systems and adaptable to single phase or other voltages. Includes pulse output and RS485 communication port supporting Modbus RTU and BACNET MSTP protocols. Measures multiple electrical parameters including voltage, current, frequency, active/reactive/apparent power, energy, and power factor.

Programmable functions such as baud rate, parity, stop bits, and security code access for programming. Operating temperature range from -20°C to 70°C suitable for diverse environments. Compliance with several IEC standards ensuring reliability and safety.

Suitable for use in industrial power management, building automation systems, gensets, low to high voltage control panels, and other commercial electrical measurement applications. HOBUT energy meters provide precise data for energy conservation and cost management.
