The DBX-6000 is fundamentally different from the other DBX models because it is designed for prepayment (pay-as-you-go) metering, while DBX-2000/3000/4000/5000 are all standard post-payment revenue-metering boxes. Key differences: (1) Meter type — DBX-6000 accepts a single-phase prepayment meter with a magnetic card or IC card interface; the others accept standard credit meters. (2) External card slot — DBX-6000 has a weatherproof external card slot or keypad so the consumer can top up credit without opening the meter compartment; the others have only a transparent reading window. (3) Indoor/outdoor — DBX-6000 is available in an outdoor IP54 UV-stabilized ABS variant; the others are IP30/IP40 indoor only (except as noted). (4) Revenue model — DBX-6000 supports upfront payment and automatic disconnection on credit expiry; the others rely on conventional meter reading and billing. Choose DBX-6000 for prepayment schemes, rental properties, arrears recovery, or any application where pay-as-you-go metering is desired. Choose the other DBX models for conventional credit-metering installations.

The DBX-6000 integrates the prepayment meter's card reader or keypad interface through the enclosure door, so the consumer interacts with it from the outside: (1) Magnetic/IC card — the consumer purchases a prepaid card (or has their existing card reloaded with credit) from a utility vending point, agent, or mobile-money platform, inserts it into the external card slot behind the spring-loaded weatherproof flap, and the meter reads and adds the credit. The card is then removed. (2) Keypad / STS token — the consumer buys a 20-digit (or similar) token code and enters it via the external keypad; the meter validates the token and adds the credit. (3) No compartment opening — in both cases, the sealed meter compartment remains closed and locked, so the utility's tamper-evident seal is never disturbed during top-up. The transparent window lets the consumer confirm the new balance. This self-service top-up eliminates the need for utility staff to visit each premises for credit loading, significantly reducing utility operational costs.

When the prepaid credit is exhausted, the prepayment meter automatically disconnects the supply to the consumer's installation (the consumer-side MCB and downstream circuits are de-energized). Most prepayment meters also provide a configurable low-credit warning — when the remaining balance drops below a set threshold (e.g., 10 kWh or a monetary value), the meter sounds a buzzer or displays a warning, giving the consumer time to purchase more credit before disconnection. Some meters also offer an "emergency credit" facility that allows a small amount of additional credit to be used once, so the consumer is not left without power at night or when vending points are closed. The utility-side incoming supply remains live; only the consumer side is disconnected. To restore supply, the consumer simply tops up via the external card slot or keypad — no utility visit is required. This automatic disconnection/reconnection is the core of prepayment metering's revenue-protection benefit.

Yes — the DBX-6000 has a dedicated outdoor variant. Protection details: (1) Indoor variant — IP30/IP40, cold-rolled steel with anti-corrosion powder coating, for meter cupboards, corridors, and utility rooms. (2) Outdoor variant — IP54, UV-stabilized engineering ABS plastic enclosure with enhanced gasket sealing around the door and a weatherproof spring-loaded flap over the external card slot/keypad. Suitable for direct exposure to rain and sunlight (UV-stabilized material prevents brittling and discoloration). (3) Both variants are wall-mounted. For fully exposed outdoor installation, the outdoor IP54 variant is appropriate; cable entries must use IP-rated cable glands and the enclosure should be mounted vertically with the card slot facing away from direct rain splash where possible. (4) The outdoor variant is ideal for utilities that prefer to install the meter at the point of supply entry (e.g., on an external wall or pole-top kiosk) rather than inside the premises, improving meter access control and security. For installations requiring higher protection (IP65) or submersion resistance, consider the JP series outdoor distribution box.

Revenue protection is central to the DBX-6000's design: (1) Sealed meter compartment — the meter and its terminals are housed in a utility-controlled compartment sealed with a utility-standard lock or padlock; any unauthorized opening breaks the seal and is immediately visible to utility staff during inspection. (2) External card slot only — the consumer can only interact with the meter through the card slot/keypad, which is read-only for credit input; they cannot access the meter terminals, wiring, or calibration settings. (3) Prepayment logic — tampering that bypasses the meter (e.g., bridging the load side) is easier to detect because the meter's recorded consumption will be zero while a load is connected; utilities can flag anomalies. (4) Tamper detection in the meter — modern prepayment meters include internal tamper sensors (cover-open detection, magnetic field detection) that log events or even disconnect the supply on tamper attempt. (5) Separation — the utility side (meter, seals) and consumer side (MCB) are physically partitioned, so consumer access to the MCB does not expose the meter. This layered approach makes the DBX-6000 well-suited to utilities concerned about non-technical losses and arrears.

The DBX-6000 is designed to accommodate standard single-phase prepayment meters with magnetic card or IC card interface from most major manufacturers (e.g., Hexing, Wasion, Holley, EDMI, Landis+Gyr, Iskra, or local utility-specified brands), provided they meet the standard single-phase meter form factor. When specifying, indicate the meter brand and model so we can: (1) Confirm the meter dimensions fit the metering compartment. (2) Pre-configure the external card slot/keypad opening position to align with the meter's card reader or keypad. (3) Ensure the transparent window aligns with the meter's display. (4) Pre-wire the meter terminals to the incoming and outgoing busbars per the meter's wiring diagram. STS (Standard Transfer Specification) token-based prepayment meters are also compatible when the meter has a keypad interface. We can supply the DBX-6000 either empty (for the utility to install their own meter) or pre-fitted and wired with the specified prepayment meter. Always confirm the meter model with the utility company before ordering, as prepayment meters are often utility-proprietary.
