Single-phase STS prepayment meter
Engineered for high-density residential feeders with integrated 100A latching relay. Features bi-directional optical communication, encrypted 20-digit token input, and active neutral tamper detection.
Three-phase commercial smart meter
Designed for commercial complexes and industrial power feeders requiring whole-current or CT-operated metering. Supports multi-tariff time-of-use registers, power quality event logging, and secure RS485 telemetry.
Customer interface unit keypad
Wall-mounted customer keypad interfacing wirelessly with split metering units up to 150 meters away. Provides instant balance inquiries, audible low-credit alarms, and historical consumption readouts.
Built to utility tolerances
Every meter batch undergoes endurance calibration and environmental stress testing before delivery to regional distribution substations.
IP54 ingress protection
Class 1.0 accuracy active energy
Tamper-detection circuitry
Flame-retardant UV-stabilized polycarbonate enclosures withstand extreme monsoon humidity, persistent dust infiltration, and seasonal ambient thermal swings across regional operating zones.
Compliant with IEC 62053-21 standards for active metering. Precision internal shunt resistors maintain measurement integrity despite voltage fluctuations between 130V and 280V.
Continuous monitoring for terminal cover removal, bypass current, reverse energy flow, and strong external magnetic fields, recording tamper timestamps directly to non-volatile flash storage.
