Introduction
This meter is designed and manufactured with stable, low-power
industrial-grade components and SMT technology. It has reliable and
stable performance and is suitable for small and medium-sized
enterprises, residential communities, apartment dormitories and
shopping mall tenants that implement single-rate electricity prices
to achieve IC card prepaid recharge management. Product standards:
GB/T17215.321, GB/T18460.3-2001.Transform energy consumption into a seamless, secure, and automated
process with our cutting-edge IC Card Prepaid Single/Three-Phase
Energy Meters. Designed for residential, commercial, and industrial applications,
these meters combine high-precision metering with advanced prepaid
functionality, empowering users to optimize costs, prevent revenue
loss, and enhance operational efficiency.
Core Functional Advantages
Automated Billing & Cost Control
Zero Revenue Leakage: Eliminate arrears with upfront payments and
automatic disconnection.
Peak-Load Optimization: Set tariff tiers (peak/off-peak) and load
limits (e.g., 40A max) to incentivize off-grid usage810.
User Safety & Device Protection
Relay Control Logic: Configurable for direct trip (e.g., magnetic
relays) or external actuator signals (e.g., shunt releases)210.
Overload/Overturn Voltage Protection: Instantly cuts power during
surges (>120% V) or excessive loads, safeguarding appliances69.
Advanced Analytics & Usability
LCD/LED Dual Display: Real-time cycling of kWh used, balance,
voltage, and alarms310.
Hourly Data Logging: Stores 7-day consumption patterns for demand
forecasting10.
"Stored Credit" Cap: Block overstocking (e.g., max 9999 kWh) to
mitigate financial risks10.
Target Applications
Multi-Tenant Buildings: Sub-metering with per-unit billing14.
Industrial Parks: High-current (CT-compatible) monitoring for
machines28.
Renewable Integration: Solar/wind feed-in tracking with net
metering8.
Remote Sites: Off-grid prepaid systems using GSM/vending kiosks5.
Quality Assurance & Compliance
Certifications: CE, RoHS, MID (optional), CCC, ISO900136.
Durability: Fire-retardant PC+ABS casing (-25°C to +60°C
operation), 20-year lifespan310.
Warranty: 12-month coverage with lifetime technical support5.
Product features
1. Single/three-phase active energy metering, reverse power is
included in the forward power.
2. LCD displays total power consumption and remaining power.
3. One meter and one card are encrypted and used independently,
which is safe and reliable.
4. The logical encryption card supports prepayment function, pay
first and then use electricity.
5. Power overload alarm tripping and power prepayment.
6. Equipped with a stand-alone prepayment system, the card reader
is connected to the computer for simple operation.
7. Phase loss metering of three-phase electricity meter, if any one
or two phases of the three phases are powered off, the metering
accuracy will not be affected.
8. Working temperature: -20℃~+55℃.
9. Extreme temperature: -25℃~+70℃.
