FAQ
The main difference lies in certification and target market.
ADL400N-MID: MID B+D certified, compliant with EU Directive 2014/32/EU and EN 50470-3, suitable for European market and applications requiring legal metering certification.
ADL400N-CT: Standard version, suitable for markets and applications without MID requirements.
Selection Guide: Choose ADL400N-MID for trade settlement, tenant billing, or other legal metering applications in Europe; choose ADL400N-CT for other scenarios.
MID certification is a mandatory requirement for measuring instruments in the European market, offering the following value:
Legal Compliance: MID-certified meters are mandatory for trade settlement, tenant billing, feed-in energy metering, and similar applications in Europe.
Metering Credibility: Certification ensures accuracy and long-term stability, providing fair and reliable measurement for both parties.
Market Access: MID certification is the passport to the European market.
Quality Assurance: The certification process includes rigorous type testing and factory inspection, ensuring higher product quality.
ADL400N-MID supports two CT specifications:
- 0.5-10(80)A: For circuits with max current up to 80A
- 0.5-10(120)A: For circuits with max current up to 120A
The CTs feature split-core design for easy installation without disconnecting primary cables, ideal for retrofit projects. Choose based on actual load current.
Summary
ADL400N-MID offers MID B+D certification, 50ms fast response, and 3-phase external CTs for EU markets. It ensures legal metering compliance and accurate monitoring for commercial solar systems.
