Gateway Energy Meter

Product Details:

Atmospheric pressure: 63.0kPa～106.0kPa (at altitudes up to 4000m)

Voltage range: After applying 380V AC voltage to the voltage circuit for 1 hour, the energy meter remains undamaged and fully operational.

Clock accuracy: Equipped with a built-in hardware clock circuit featuring temperature compensation, supporting calendar, timing, and automatic leap year conversion functions; internal clock terminal output frequency is 1Hz. Within the temperature range of -25℃ to +60℃, clock accuracy is ≤±1s/d; at reference temperature (23℃), clock accuracy is ≤±0.5s/d. Lithium battery capacity: ≥1.2Ah, providing clock operation for ≥5 years after power failure.

Data retention time after power failure: ≥10 years

Energy LCD display: 0 kWh～999999.99kWh.

Battery: Utilizes a long-life eco-friendly lithium battery with a capacity of ≥1.2Ah, requiring no replacement during the energy meter's lifecycle. The meter automatically alerts and alarms when battery voltage is low.
