Лондиан: Your Premier DIN Rail Meter Manufacturer for Smart Grid Innovation

Introduction to DIN Rail Meter Technology

Modern energy management relies heavily on the DIN rail meter. This compact device has become essential for electrical infrastructure. As a leading DIN rail meter manufacturer, Londian drives this technological revolution. Since 1996, Londian has leveraged nearly three decades of industry expertise. Our cutting-edge metering solutions combine precision, reliability, and smart grid interoperability.

DIN rail meters, or modular meters, measure energy consumption in standard DIN rail mounting systems. Their space-efficient design, roughly 50% smaller than conventional meters, suits space-constrained environments perfectly. Residential complexes, commercial buildings, and industrial facilities all benefit from this compact form factor.

Londian’s Flagship DIN Rail Meter: The LD108 Series

Londian’s LD108 series represents the pinnacle of our DIN rail meter portfolio. This single-phase smart prepaid DLMS electricity meter exemplifies modern metering innovation. Moreover, its sophisticated technical capabilities distinguish it in the competitive market landscape.

Technical Specifications

The LD108 series demonstrates Londian’s engineering excellence through several key parameters:

• Диапазон напряжения: Ultra-wide 70-312V (0.7Un-1.3Un) operation ensures grid compatibility

• Current Options: Configurable 5(40)A to 5(100)A accommodate varying load requirements

• Accuracy Class: Class 1/B for active energy (±1%) and Class 2 for reactive energy (±2%)

• Диапазон температур: Reliable operation spans -25°C to +55°C for various installations

• Protection Rating: IP51-rated enclosure protects against dust ingress and condensation

International Certifications: A Mark of Quality

International standards and certifications distinguish a premier DIN rail energy meter manufacturer. Londian’s meters hold numerous globally recognized certifications. These attest to our unwavering commitment to quality and compliance.

DLMS Certification

The DLMS User Association officially awarded the LD108 with DLMS UA certification (DLMS-UA-3423). This certification confirms compliance with international data exchange and protocol standards. Consequently, smart grid interoperability becomes seamless. Furthermore, Londian’s DIN rail meters communicate effortlessly with utility head-end systems. Additionally, standardized data exchange operates across different manufacturers’ equipment.

MID and EU-Type Examination

For European markets, Londian’s meters hold EU-Type Examination certificates (certificate number 1093-19). These attest to compliance with Directive 2014/32/EU on measuring instruments. Rigorous testing protocols include EN 50470-1:2006 and EN 50470-3:2006. Therefore, this compliance becomes mandatory for billing applications across EU member states.

The PTB/Eichrecht certification from Germany’s Physikalisch-Technische Bundesanstalt further underscores Londian’s commitment. Legal metrology compliance ensures long-term stability and tamper-proof design. Moreover, environmental durability satisfies requirements throughout Germany, Austria, Switzerland, and other EU markets.

Advanced Communication and Smart Grid Integration

Advanced communication capability distinguishes modern DIN rail meters. Londian’s LD108 features a hybrid communication system offering unparalleled deployment flexibility:

The meter’s DLMS/COSEM protocol stack supports automatic protocol negotiation. Consequently, dual-stack communication (IPv4/IPv6 ready) becomes possible. For cybersecurity, 128-bit AES encryption secures all remote communications. Meanwhile, TLS 1.3 further protects data during transmission.

Prepayment Functionality and Customer Interface

Londian’s prepayment-enabled DIN rail smart meter offers advanced features for utilities and end-users. Integration with Customer Interface Units (CIUs) provides real-time balance alerts. LED indicators or SMS notifications deliver these alerts effectively. Moreover, the system supports multiple tariff structures including Time-of-Use (TOU) and critical peak pricing.

Key utility management features include:

• Remote disconnect/reconnect capability

• Credit threshold configuration with automated alerts

• Tamper event logging with storage for the last 10 incidents

• Load profile recording at 15-minute intervals

• QR code payment integration for convenient top-ups

Anti-Tamper and Security Systems

Revenue protection remains paramount for energy utilities. Londian’s DIN rail power meter incorporates multi-layer physical protection mechanisms. These include magnetic field detection and neutral line current monitoring. Additionally, cover position sensors and terminal block tampering detection provide comprehensive security. Consequently, these robust security features ensure accurate billing and prevent energy theft.
