Narrative

Technical Innovation & Quality Heritage

YTL’s Integrated Keypad Prepayment Meters are the all-in-one answer for simple, cost-effective revenue management. Featuring a built-in 12-key tactile keypad and a high-contrast LCD, these meters allow for direct credit loading at the point of measurement. As a world-class manufacturer, Zhejiang Yongtailong has built these meters to meet the global Standard Transfer Specification (STS), ensuring compatibility with any STS-compliant vending system. These meters are designed for easy wall-mount installation and are perfect for regions where a split-system is not required. With an internal 100A relay, the meter automatically disconnects power when credit is exhausted and reconnects instantly when a valid 20-digit token is entered. Rugged, reliable, and user-friendly, our integrated keypad meters provide a transparent "pay-as-you-go" energy experience for millions of users worldwide.

Product Application

  • Residential Revenue Collection
  • Rental Property Portfolios
  • Commercial Kiosk Metering

Residential Revenue Collection

The standard solution for municipal utilities looking to implement a prepaid billing model. These meters allow the utility to collect payments upfront, reducing the administrative burden of debt collection and helping households manage their monthly budgets by seeing exactly how much energy they have left in real-time.

Rental Property Portfolios

Ideal for landlords managing multiple single-family rentals. By installing an integrated keypad meter, the landlord can ensure that the tenant pays for all electricity before use, preventing the risk of unpaid utility bills when a tenant moves out and simplifying the management of short-term leases.

Commercial Kiosk Metering

Perfect for small retail shops and kiosks in markets or transport hubs. Each shop owner can manage their own energy credit independently. The compact, all-in-one design makes installation fast and simple for electrical contractors working in dense commercial environments.

Product Advantages

Cost-Effective Design

Combines measurement, communication, and user interface into a single unit, providing the lowest upfront equipment cost for a complete prepayment solution.

Intuitive User Experience

The tactile keypad and clear LCD messages (like "Accept", "Old", or "Reject") make it easy for users of all ages to manage their electricity tokens without technical assistance.

Robust Load Control

Features a high-quality magnetic latching relay that can handle thousands of switching cycles, ensuring reliable power disconnection even under full 100A loads.

Frequently Asked Questions

  • Q: Can I load credit via my phone?

    A: Yes. You can buy a 20-digit token through a mobile app or SMS, and then manually type that token into the meter's keypad to load your credit.

  • Q: What happens if I type the wrong number?

    A: The meter will show a "Reject" or "Error" message. You can simply press the backspace key or wait a few seconds to start typing the 20-digit code again.

  • Q: Can the meter detect if someone opens the cover?

    A: Yes, it has a built-in tamper switch. If the cover is opened, the meter will trip the relay and disconnect power until an authorized technician resets it.

  • Q: Is there an alarm for low credit?

    A: Yes, the meter has a built-in buzzer that will sound when your credit reaches a pre-set low level, reminding you to purchase a new token before the power goes out.

  • Q: Does it work during a power failure?

    A: The meter saves all credit data during a failure. Once the grid power returns, the meter wakes up and restores your previous credit balance and power status.
