DBX-6000 Type Magnetic Card Prepayment Meter Box
DBX-6000 type magnetic card electric meter box is a terminal distribution enclosure specifically designed for installing single-phase prepayment electric energy meters (220V) that utilize magnetic card or IC card keypad top-up systems. The enclosure provides a secure, tamper-proof housing for the meter and associated card reader interface, enabling utility companies to implement prepayment metering schemes where consumers pre-purchase electricity credit via magnetic card or smart card and load the credit onto their meter through a reader accessible from the outside of the enclosure without requiring meter compartment access.

Key Features
- Prepayment Meter Compatible: Specifically designed to accommodate single-phase prepayment (pay-as-you-go) electricity meters with magnetic card or IC card interface — the enclosure provides a secure housing for the meter body while allowing external card reader access for credit top-up without requiring utility staff to visit the premises
- External Card Slot Interface: A dedicated card slot or keypad access window is integrated into the enclosure door, protected by a weatherproof spring-loaded flap — allowing the consumer to insert their prepayment card or enter top-up codes without opening the sealed meter compartment, maintaining the security and tamper-evident integrity of the metering installation
- Tamper-Evident Revenue Protection: The meter compartment is designed with utility-standard locking and sealing provisions to prevent unauthorized access to meter terminals, internal wiring, and metering calibration settings — critical for prepayment metering applications where revenue protection and tamper detection are primary security concerns
- Dual Indoor/Outdoor Configuration: The DBX-6000 is available in both indoor and outdoor weatherproof configurations, with the outdoor variant featuring enhanced gasket sealing, UV-stabilized enclosure materials, and weather-protected card slot hardware — enabling flexible installation at the point of supply entry regardless of indoor or outdoor meter location requirements
