Product Overview

Single Phase Reset Din Rail Energy Meter is engineered for highly accurate, stable, and cost-effective sub-metering in residential, commercial, and multi-tenant environments. Featuring a standard compact DIN rail layout, it allows rapid integration into modular distribution panels and energy management systems.

Manufactured under our ISO9001:2015 certified production system, every single unit undergoes strict 100% dual-stage testing and calibration according to IEC standards to ensure out-of-the-box measurement consistency before global shipment.

Target Applications

Unlike standard utility meters, this manual-reset energy meter is optimized for specialized commercial and sub-metering scenarios:
Rental Properties & Apartments: Landlords can easily reset the meter to zero when a new tenant moves in to track individual billing cycles.

EV Charging Station Sub-metering: Track the exact energy consumed during a single electric vehicle charging session.

Co-working Spaces & Shared Offices: Monitor and bill the specific power usage of individual startup booths or shared equipment.

Marinas, Campsites & Caravan Parks: Ideal for tracking temporary power connections for boats, RVs, and mobile homes.

FAQ

Q: Are your meters certified for European and international markets?

A: Yes. This series is fully CE certified and complies with IEC 62053-21 Class 1.0 accuracy and RoHS environmental directives, ensuring smooth customs clearance and regulatory compliance in global markets.

Q: What is your production capacity and delivery lead time for bulk wholesale orders?

A: Supported by our 1,600 m² facility and 3 active assembly lines, standard B2B wholesale orders are generally dispatched within 15 to 30 days, depending on your specific customization requirements.

Q: How do you maintain measurement consistency across large batches?

A: Human error is minimized through high-level automation. Every single unit undergoes a mandatory dual-stage automated testing process-including individual accuracy checks on our multi-position computerized calibration systems-to keep the error margin strictly within Class 1.0 limits.

Q: Do you offer OEM/ODM customization and private labeling?

A: Yes. Utilizing our in-house automated laser-marking machinery, we can permanently engrave your brand logo, specific current/voltage parameters, and customize regional packaging according to your commercial requirements.

Q: What is your warranty and defect policy for international distributors?

A: We back our quality with an 18-month factory warranty from the date of shipment. Any verified manufacturing defects or quality non-conformances are resolved via direct product replacement or credit allocations in your subsequent order batch.
