The function of bidirectional active power metering can accurately measure the active energy in both positive and negative directions, and accumulate in one direction. It has the function of preventing electricity theft. And will sell electricity to the next time when purchasing electricity.

The system feedback the information.

QPM11B uses IC cards and cooperates with advanced AES encryption technology to ensure that one table, one card is not interchangeable and can be recharged repeatedly. Consumers purchase their own electricity, do not come to the meter reading, charging, the implementation of electricity after the first purchase.

QPM11C uses IC card and cooperates with advanced AES encryption technology to realize multi-card with one meter, each watt-hour meter can be used by multiple users.

QPM11I uses infrared remote control card and cooperates with advanced AES encryption technology to ensure that one meter and one remote control is not interchangeable and repeatable. Consumers purchase their own electricity, do not come to the meter reading, charging, the implementation of electricity after the first purchase.

Flexible tariff setting allows different users to adopt different tariffs and to adjust instant updates to suit the current special user base.

Supporting multiple power selling modes, the MIS system can be configured as a stand-alone or network version. Even if users charge the purchased cards locally or remotely, they are not exclusive and compatible with each other.

Has the consummation many kinds of fault self-examination function, once has the special fault, the ammeter displays the corresponding instruction, reminds the user to remove the fault.

QPM11B and QPM11I have the function of overdrawing electricity charges, which are automatically deducted when the card is charged next time.

QPM11C users can return the remaining electricity charges to their purchase cards at any time.

It has overload detection function, and the capacity limit can be preset by setting the card.

It has the function of presetting the electricity fee, and the electricity meter installed by the user can use electricity first. The pre installed electricity charge is automatically deducted when the account card is opened for charging the account.

Double alarm prompt function, when the user's pre-order amount is used up, when the remaining amount is less than the display alarm amount (first alarm), the meter for visual warning. The remaining amount is less than the gate alarm.

When the two level alarm is applied, the power is cut off for 2 minutes to remind users to purchase electricity. Plug in the card or restore power automatically after 2 minutes, until the remaining amount in the table below the current price will be permanent power cut.

IC card seat self-protection function, when the metal sheet and other foreign materials inserted into the card seat, the card reading mechanism automatically protects but does not affect the normal measurement and other functions, to ensure that the watt-hour meter will not be damaged.

Has the reliable power failure protection function, the data does not lose after the power failure, maintains 100 years unchanged, power can be restored.

Adopt a new large current magnetic latching relay with low power consumption and high reliability.
