Split Layout: (BS footprint, DIN rail)

Split Prepayment Meters

• BS footprint• Single and 3 phase

PLC Communication

Single split prepayment meter HXE 12

PLC Communication

• DIN rail• Single phase

Single phase split DIN rail prepayment meter

DIN Rail Meter

Credit Status- Green = enough credit- Red = remaining credit less than 1st alarm- Flashing Red = credit less than 2nd alarm

Why PLC

PLC = Power Line Carrier (Communication)

ADVANTAGE• No pilot wires• Ease of installation• Lower installation cost• Up/down link communication ready
