10A 3 Phase Prepaid Electricity Meter with 400imp/kWh STS Standard and Split Keypad Design
Our STE38-S STS Standard Split Keypad Prepaid Three Phase Electricity Meter features a separate customer interface unit (CIU) for convenient operation. This advanced metering solution enables precise electricity consumption monitoring and prepaid billing functionality.
