Understand the market prospects and features of prepaid energy meters

Views: 信息来源:山东科大中天电子有限公司 发布时间:2018/1/13 Source of information: Shandong University of Science and Technology Zhongtian Electronics Co., Ltd. Release time: 2018/1/13
Market outlook for prepaid energy meters :
1. It is suitable to solve the three-phase prepaid electricity meter for small and medium-sized power users / commercial and residential users with large liquidity and tendency to owe money.
2. It is suitable to solve the problem of one-phase multi-card three-phase prepaid watt-hour meter used in irrigated land by multiple farmers' families.
3. It is suitable for the three-phase multi-rate pre-paid electricity meter with the rate and time period.
4. A single-phase multi-rate prepayment meter suitable for implementing the time-of-use electricity price policy for residents.
5. Single-phase prepayment meter suitable for ordinary residents.
Pre-paid energy meter features
I. Features of prepaid energy meters:
1. Large-scale integrated circuits and SMT processing technology are used to ensure high reliability of the product, low power consumption of energy meters, far less than the national standard requirements, voltage lines: ≤0.7W and 4VA (national standards: ≤2W and 10VA), current Line: ≤0.3VA (GB: ≤4.0VA) Strong anti-theft function. The single-phase electronic energy meter produced by our company adopts advanced anti-theft technology. It not only prevents ordinary power stealing methods such as meter tilt, external magnetic field, short circuit, reverse power consumption, etc., but also has the function of preventing power theft from one fire and one place.
量程宽,保证在6倍以上过载倍数。 2. In terms of structure, it is designed with an anti-theft end cover to prevent short-circuiting and stealing. The meter has a wide measuring range and guarantees an overload multiple of 6 times.
具有防潜动逻辑电路,施加125%的电压, 电能表无测试脉冲输出, 电能表在0.4%Ib时,电度表能起动并记录电能表工作电压范围宽:在长期误加380VAC时,电能表仍能正常工作。 3. The energy meter has anti-submergence logic circuit, applying 125% voltage, the energy meter has no test pulse output, and when the energy meter is at 0.4% Ib, the energy meter can start and record the wide working voltage range of the energy meter: At 380VAC, the energy meter can still work normally.
Second, the function of pre-paid energy meters :
1. Automatic power off after the purchased electricity is used
2. Load control can be selected, delayed overload power failure
3, the remaining power shortage alarm, remind users to purchase electricity in a timely manner
4. The LCD screen displays the power consumption information for the convenience of users.
5.The LCD screen displays both the accumulated power and the remaining power at the same time.
6. ISO standard IC card adopts special data dynamic encryption algorithm, which is ** reliable, one table and one card
7, large-capacity meter reading card, meter reading in place, accurate
8. The power purchase card automatically copies the power consumption information for easy management and verification of user information
9. Dedicated setting card and meter changing card, convenient for management department registration and maintenance
10. Using power-down processing technology to ensure that data will not be lost for 30 years after power-down
