Narrative

Technical Innovation & Quality Heritage

YTL’s DIN Rail Prepayment Meters combine the security of the STS (Standard Transfer Specification) protocol with the space-saving convenience of a 35mm DIN rail mount. As a market-leading manufacturer, Zhejiang Yongtailong has developed these meters to help landlords and utilities manage energy credit without the need for large, bulky enclosures. These meters support both local keypad token entry and remote cloud-based recharging. With an integrated high-capacity latching relay, they automatically disconnect power when credit reaches zero. This modular design is perfect for multi-tenant apartments, dormitories, and shopping kiosks, providing a professional, automated "pay-as-you-go" solution that eliminates the risk of utility debt and simplifies property management.

Product Application

  • Rental Apartment Billing
  • Student Housing Management
  • Commercial Retail Kiosks

Rental Apartment Billing

Designed for property owners who want to eliminate the hassle of chasing tenants for monthly electricity payments. By installing a DIN rail prepayment meter in the unit's distribution board, the landlord ensures that energy is paid for upfront. Tenants can purchase credit online and enter the token through a mobile app or a local keypad. This "pay-as-you-go" model provides financial security for the owner and helps tenants stay within their budget by providing clear visibility of their remaining energy balance.

Student Housing Management

Ideal for university dormitories where energy usage needs to be strictly managed for safety and cost control. These meters allow the university to set daily energy limits or "emergency credit" for students. The compact DIN rail form factor allows multiple meters to be installed in a single floor-level cabinet, saving significant hallway space. Advanced features like malignant load detection can automatically cut power if students use unauthorized high-power heating appliances, ensuring dormitory fire safety.

Commercial Retail Kiosks

Perfect for temporary stalls in shopping malls or street markets where vendors change frequently. Prepayment ensures that each vendor pays for exactly what they use before their lease ends. The meter's small size allows it to be tucked away in a tiny electrical box within the kiosk. With integrated RS485 communication, the mall's central management can monitor usage across all stalls remotely, ensuring no unauthorized tapping of the power supply occurs during high-traffic events.

Product Advantages

Ultra-Compact Footprint

Occupies minimal space in the distribution board, allowing for high-density installations in multi-unit buildings where cabinet space is at a premium.

Secured Revenue Stream

Utilizes the globally recognized STS encryption standard, ensuring that tokens cannot be forged and utility payments are collected before consumption begins.

Automated Load Control

Features an internal relay for automatic disconnection upon credit exhaustion or overload, reducing the need for manual site visits to manage accounts.

Frequently Asked Questions

  • Q: Can I recharge the meter remotely?

    A: Yes, if the meter is equipped with a communication module (Wi-Fi/4G), tokens generated by the vending system can be sent directly to the meter via the cloud.

  • Q: What happens if the tenant enters the wrong token?

    A: The meter will display a "REJECT" message. STS tokens are unique to each meter's serial number and cannot be used on other devices or entered incorrectly.

  • Q: Does it have a low-credit alarm?

    A: Yes, the meter can be programmed to beep or flash the LCD backlight when the credit falls below a certain threshold to warn the user to top up.

  • Q: Can I set different tariffs for weekends?

    A: Absolutely. Our prepayment meters support complex Multi-Tariff (TOU) configurations even in prepaid mode, allowing for weekend or holiday pricing.

  • Q: Is it difficult to install?

    A: No, it snaps onto any standard 35mm DIN rail just like a circuit breaker, making it very easy to integrate into existing electrical panels.
