Three Phase Four Wire IC Card Prepaid Energy Meters with LED Display
DTSY150D electric meter is worked by contact type IC card.However, open IC card, which is easily affected with the environment, need to be protected and will creates extra expense and inconvenience.
Therefore, Radarking designs a kind of prepaid electronic meter with contact-less RF technology, that is, the purchased credit is access into the meter through contact-less IC card, the unit price of kWh can be set in card, and the meter will deduct the credit based on each 0.01kWh, when the tariff is changed, the management system will reset the card to change the unit price of the meter,so that the meter can deduct the credit with the adjustment of the unit price to reduce the consumption of power company.

Electric Power Measurement-- Positive active power and reverse active power which can be measured.
Prepayment-- IC Card prepaid, electricity sector receive energy charge in advance through selling IC Card. User pay first.
Ladder Billing-- Two schemes for electricity price. It can automatic changeover when at promissory time or reach certain value.
Manner of Working-- Warning/Overdraw Manner. Warming/Overdraw electricity, maximum accumulations can be set.
Protections-- Over Voltage, Over Current, Over Load Protections.
Display Method-- LED or LCD display the rest electricity(charge), cumulative electricity consumption, current power in alternant way.
Reliable Design-- Perfect power source and electromagnetism compatible design, which are suitable to the strong electromagnetism disturbance and big occasion of power source fluctuation.
Cover for Meter-- Fully sealed dustproof and waterproof design, material of cover has excellent flame retardant and anti-corrosion, anti-aging properties.
