Main Usages:

Used to measure active and reactive electric power that is requires both timesharing and prepayment. It's an effective technical method to solve the problem payment default in electric power consumption. Adopted and used by tens of electric departments and with up to 10000 meters operating with high or low-voltage at site, its multi-functional prepayment device is well proved for its reliability, unique design and practicability. Having consulted and modified with tens of electricity departments, the management software accords with present management mode and has remarkable effect in elimination payment default. It is a good and cheap method for improving economic efficiency of electricity department.

Main Functions:

1. Prepayment, compound rates, demanded quantity of active and reactive electric power, and power factor can be combined optionally.

2. Parameters can be transmitted be infrared portable computer, RS458 interface, international standard IC card or manual operation at the user's option.

3. Displays and records all data of electric power, maximum requirement, power factor and phase failure and perform automatic accounting and settlement.

4. Copy function. When changing Watt-hour Meter, all data in the original meter can be copied to the new one by copy card. It is quick and convenient to program and change.

5. The interface of electricity sales system is friendly, precisely structured and easy to lean. And able to make sales to both 3-phase and single-phase prepayment Watt-hour Meter on the system manufactured by our company.

Main Characteristics:

1. High accuracy, high overload, high reliability, low power consumption, small volume, light in weight and good structural performance.

2. The internationally advanced integration circuits specially used for Watt-hour Meter, permanent information keeping non-volatile storage and other hardware and software measurements are employed to prevent the meter from losing data at times when both AC power supply and internal support battery lost voltage.

3. Big Chinese menu, STN, LCD display, clear and complete.

4. The interface of electricity sales system is friendly easy to lean.
