Product Features and Applications

The DTSY1607 Three Phase IC Card Prepaid Energy Meter is designed for reliable energy management in industrial, commercial, and residential power distribution systems. Combining accurate three-phase active energy measurement, prepaid electricity management, load control, and user information management functions, this smart prepaid meter helps power suppliers improve electricity management efficiency while providing users with convenient energy consumption control.

When selecting a high-performance Three Phase IC Card Prepaid Energy Meter, facility operators require stable operation under heavy loads and changing power conditions. The DTSY1607 is equipped with an intelligent load monitoring system. When the connected load exceeds the preset power limit, the indicator light provides an overload warning. If the overload condition continues, the built-in high-capacity magnetic latching relay automatically disconnects the power supply to protect electrical equipment and the power network. Power can be restored after inserting a valid prepaid IC card, ensuring secure and efficient electricity usage management.

With its reliable prepaid control function, multi-tariff electricity measurement, and remote data management capability, the DTSY1607 is widely applied in factory workshops, commercial buildings, shopping centers, industrial parks, and large residential communities.

Application 

The DTSY1607 is a new-generation three-phase IC card prepaid energy meter developed for modern electricity management systems. It integrates electricity measurement, time-of-use tariff management, load control, and customer information management functions, making it an ideal solution for upgrading traditional power consumption systems and improving energy management efficiency.

The meter complies with the technical requirements of IEC 62053 standards for electricity metering equipment, ensuring accurate measurement, reliable operation, and long-term service performance.

Key Features

• High-Accuracy Three Phase Energy Measurement: Measures three-phase active energy with stable accuracy and requires no calibration during long-term operation.
• Reliable Operation Under Phase Loss Conditions: The three-phase power supply design maintains accurate metering even when one line (three-phase three-wire system) or two wires (three-phase four-wire system) are disconnected, with phase loss and voltage indication functions.
• Secure IC Card Management: Each meter is matched with a dedicated IC card to prevent unauthorized use and improve electricity management security.
• Low Balance Warning Function: When the remaining electricity balance approaches the preset warning level, the digital display alerts users to recharge in advance.
• Automatic Power Cut-Off: The meter automatically disconnects power when prepaid electricity is exhausted or when overload conditions occur.
• High-Capacity Magnetic Latching Relay: The built-in relay provides high switching capacity with low power consumption, ensuring reliable load control.
• Convenient Data Management: Data copying and communication functions simplify electricity data collection and improve management efficiency for power departments.
• Prepaid Electricity Control System: Supports electricity selling and consumption control functions through IC card management technology.
• Multi-Tariff Energy Management: Supports four tariff periods, including peak, flat, off-peak, and special periods, allowing flexible electricity pricing management.
• Flexible Time Period Programming: Each tariff period can be programmed with up to 10 time intervals, with a minimum setting interval of one minute.
• Clear Digital Display: Uses a six-digit digital tube display, including five integer digits and one decimal digit, with data available for copying through handheld devices and RS485 communication.
• Advanced Data Security: Protects stored data through password protection and hardware security mechanisms.
• Direct LED Data Reading: Provides convenient data viewing through LED indication.
• Reliable Internal Clock: Equipped with a high-performance clock system with ultra-low backup current consumption, ensuring long-term timing accuracy.

Production Details & Competitive Advantages

We believe that true quality is proven through rigorous manufacturing and real-world testing. Every batch of our DTSY1607 Three Phase IC Card Prepaid Energy Meter undergoes strict aging tests and high-voltage dielectric strength checks before leaving our factory. Compared to standard market alternatives, our internal PCB boards utilize conformal coating technology to prevent moisture and dust damage, significantly extending the service life in humid environments. Furthermore, while many competitors use basic relays prone to failure under heavy loads, we exclusively source high-capacity magnetic latching relays that ensure stable switching even during sudden power surges.

FAQ

Q: Can the three-phase IC card prepaid energy meter support external current transformers (CTs) for higher capacity?

A: Yes. For industrial applications requiring higher capacities, our Three Phase IC Card Prepaid Energy Meter supports connection with external CTs (e.g., 3x1.5(6)A specification). We will calculate and set the correct multiplier parameters into the IC card based on your CT ratio.

Q: How does the Three Phase IC Card Prepaid Energy Meter handle phase loss or voltage fluctuations in the factory?

A: The Three Phase IC Card Prepaid Energy Meter is equipped with advanced phase-loss and over/under-voltage protection. If a phase is lost or voltage becomes unstable, the meter will automatically record the event and safely cut off power to protect connected industrial equipment. It will resume operation once normal power is restored and validated via the IC card.

Transaction Security: We guarantee secure international trade terms (T/T, L/C) and provide comprehensive after-sales technical support, including free training videos for installation and software operation. Your trust is our top priority.

Real-World Success Stories (Use Cases)

Our expertise extends beyond manufacturing; we deliver tailored solutions for industrial zones. A prominent example is our successful deployment for a large-scale manufacturing park in Vietnam. The park operator struggled with severe cash flow issues caused by delayed electricity fee settlements from tenant factories and unauthorized usage of high-wattage machinery. By implementing our customized DTSY1607 Three Phase IC Card Prepaid Energy Meter system, integrated with localized backend software, they achieved 100% upfront payment collection and eliminated bad debt. Additionally, the meter's automatic overload protection successfully prevented circuit damage caused by tenants operating unapproved heavy machinery. This project not only secured their operational revenue but also drastically reduced on-site maintenance costs, proving our capability to handle complex industrial utility challenges.
