AC Energy Meter
In telecom power and energy systems, continuous visibility of electrical consumption is critical to control operating costs, ensure site uptime, and support energy audits across geographically distributed locations. The AC Energy Meter is a high-accuracy electronic metering solution designed for continuous energy monitoring in single-phase and three-phase power systems used in telecom shelters, BTS sites, data centres, and network facilities. Using Hall Effect–based non-intrusive current sensing technology, the meter delivers precise measurement of current, voltage, power, and energy parameters without interrupting live circuits. Engineered for demanding telecom, industrial, and utility environments, it offers long-term accuracy, electrical isolation, and stable performance. Its advanced sensing and communication capabilities make it ideal for telecom energy monitoring, power auditing, and remote data acquisition, enabling operators and EPCs to improve energy efficiency, monitor site performance, and support centralized energy management systems.
Construction Details:
The meter features a modular microcontroller-based architecture with isolated voltage and current input sections. The enclosure is flame-retardant ABS or polycarbonate, designed for DIN rail or panel mounting. Front fascia includes user-friendly navigation keys and status indicators for each channel.
