JYF-0.5 Type low voltage prepaid power metering device is mainly applicable to electric energy metering of systems with a rated frequency of 50 / 60Hz and rated voltage of 0.5kV and below. When the prepaid electric energy meter input card has the electric charge signal input, it can supply power normally. Once there is no electric charge, the metering box will automatically cut-off power, so as to achieve the purpose of prepayment and solve the problem of difficult collection of electric charges in the power department.
The secondary side of the transformer is equipped with an anti-theft sealing box, and the cable is directly introduced into the comprehensive metering box to eliminate electricity theft.
This product can also be equipped with a short circuit breaker to increase the protection function of the voltage regulator (it is more suitable for electric field stations such as areas, lighting, drainage and irrigation, industrial and mining, etc. without establishing power distribution, the installation on the column can be directly realized to reduce the occupation of space and facilitate maintenance.
