JYF-0.5 type low voltage pre paid power metering device. suitable for 50Hz or 60Hz three-phase AC rated voltage of 0.5kV power grid for electric metering. When the prepayment electric energy meter input card has electricity signal input, can be normal power supply, but no electricity, the metering box automatically power off, to achieve the purpose of prepaid, to solve the problem of electricity tariff collection.
This product in the two side of the transformer with anti-theft seal box, cable directly into the integrated metering box, prevent theft.
This product can also be equipped with a circuit breaker to increase the protection function of the transformer (over current velocity). More suitable for Taiwan area, lighting, drainage and mining in the field, does not need to set up a distribution room. direct installation, reduce the area of column. convenient maintenance.
This product is composed of a control cabinet and prepayment meter box control cabinet directly installed in the transformer two wire, two wire transformer is directly connected to the inlet side of AC contactor, AC contactor outlet side of the outlet through the bus type current transformer is connected with the top of the control cabinet set a porcelain screw, screw as a user connection wire. Prepaid electric energy meter box electric energy meter can not only account for electricity, and when no electricity, electric energy meter control circuit to control cabinet action, cut off the power supply, to achieve the purpose of power consumption without charges.
