Rated Voltage 220V / 230V Single Phase Smart Electric Energy Meter
Traditional prepaid electric meter is normally working by the means of Multi-Card One Meter, electricity consumption measurement or No Card to deduct the purchased electricity (unit: KWh ) after being inserted into IC Card. However, the price fluctuation of electricity market which cannot reflect in the purchased electricity will increase the losses of Power Company.
For this purpose, a new designed prepaid electric meter Model No. DDSY150 D/F/A issued by Radarking adopts the electricity fee ( Unit: CNY) way, that is, when the fee is transmitted into through Client IC Card and the meter will deduct the price of electricity ( 0.1kWh as base ) according to the unit price, which is set on the IC Card to be transferred into the meter. When the electricity rate changes, the unit price of electricity in the meter will also be changed through the communication medium IC card that the modified unit price are written into from the vending system.
1. Pay As You Go: IC card that adopts " Financial Card Project" hardware encryption technology is used by the Power Company to collect the electricity fee in advance.
2. High Reliability: The meter is combined with fully-digital metering, kWh display, prepayment control, card reading and smart anti-theft technique.
3. Overload Protection: The meter will cut off the power supply circuit automatically when the load exceeding about 20%~30% of rated Max. Current lasts for 10~15s;
4. High Security And Accuracy: The IC card is used multiple encryption via hardware and software to ensure data safety, accurate and reliable. The special design of IC Card is that it can record the the information about remaining electricity fee, accumulated electricity when the User insert it into the meter and also can reflect power stealing action.
5. Perfect Interface Protection: The meter has the capability to protect circuit against malicious attacks.
6. Scrolling Display: The show time of different metering parameters is 10s for residual electricity fee (Two decimals, CNY), 5s for unit price, 5s for accumulated power consumption (One decimal, kWh) and 5s for the current power consumption (One decimal, kWh)
7. Has the feature of partition management.
8. Supports for max. Hoarding electricity quantity and alarm mode.
9. Magnetic Latching Relay Applied: It can improve the performance of outage movement and lower the power consumption after power failure, and meanwhile, also can get rid of the contactor adhesions when the relay is being worked under the large current for a long time.
10. The meter will keep data or get recovery when being powered on. /off automatically.
