Single Phase Two Wire IC Card Electric Meter DDSY150 For The Apartment

Single Phase Two Wire IC Card Prepaid Energy Meter for the Apartment Usuage

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. Main Features: 

• Perfect Interface Protection: the meter has the capability to protect circuit against malicious attacks.
• 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)
• Easy-To-Read: The total and unit price of electricity inside the meter is accumulated in the unit of four decimals and CNY.
• Has the feature of partition management.
• Supports for max. hoarding electricity quantity and alarm mode.
• 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.
• The meter will keep data or get recovery when being powered on./off automatically.
• 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.
• High Reliability: the meter is combined with fully-digital metering, kWh display, prepayment control, card reading and smart anti-theft technique .
• 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;
• 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.

Safety precautions:
＊ Use only isolated tools.
＊ Do not connect the meter to a 3 phase - 415V AC - network.
＊ Place the meter only in dry surroundings.
＊ Make sure the used wires are suitable for the max current the meter can measure.
＊ Make sure the AC wires are installed correctly before activating the current/voltage.
＊ Do not touch the meter connecting clamps directly with your bare hands, with metal, blank wire or other material as you will have the chance of an electricity shock and a possible chance for health damage.
＊ Make sure the protection cover is placed after installation and has been sealed.
＊ Installation, maintenance and repair should only be done by a certified electrician.
