The SX1A1-SELS-05 series single-phase meters are used to measure and record the consumption of electrical power in single-phase two-wire LV networks. With advanced functionalities on smart energy management and communication capabilities over PLC, RF, GPRS, RS485, the meters are aimed to be used for AMI/AMR/AMM and smart grids.
- Up to 8 tariffs.
- Relay switch on/off function (For Remote Switch On/Off Command, Over-Power)
- Bidirectional measurement of active energy in each tariff for latest 12 months
- Communication: PLC/RF,GPRS, IR, RS-485
- Anti-tamper and event log; cover opening, power failure, time calibration, (dis)connect local load
- Measured quantities: Multi-tariff registration for active/reactive energy, load profile, maximum demand
- Tamper detection and log: cover opening, energy reversal, magnetic interference, etc
- Firmware remote upgrade
Measurement - Bidirectional measurement of active/reactive energy in each tariff for latest 12 months - Four quadrant energy measurement - Instantaneous value measurement - Freeze energy - Maximum Demand - Multi-tariff
LCD - Scrolling display - Button press display - IR operation display - Power off display - LCD backlight
Communication Interface - RS485 communication with interface in accordance to DLMS standard- Support In Home Display (optional) - PLC/GPRS
Event Record - Loss of voltage/current/phase - Over voltage/current/load - reverse, imbalance of current - Meter cover Open, Terminal cover open
