Import Electronic Multi-Rate Watt-Hour Meter — Buy in Bulk from Supplier in China

The DEM031 electronic multi-rate watt-hour meter is a single-phase DIN rail mounted device designed for precise time-of-use energy measurement. It features a 7-digit wide-temperature LCD display and supports three tariff rates with 12 daily time periods, including weekend tariff selection. The meter meets Class 1 and Class 2 accuracy standards under GB/T17215-2002 and IEC61036, with rated voltages of 220V and current ranges including 2.5(10)A, 5(30)A, 10(50)A, and 20(100)A. It automatically detects power direction and triggers fault detection without external intervention.

The meter operates with an internal clock that retains time and settings during power outages using a built-in backup battery, eliminating the need for maintenance. Communication is enabled via infrared carrier and RS485 serial port, both password-protected for secure configuration. The unit is certified for 2kV AC insulation and 6kV impulse voltage resistance. Standard mounting options include 35mm DIN rail or panel mounting, with compact dimensions suitable for dense electrical panels. Typical industry applications require meters with these communication and tariff capabilities for commercial and industrial load profiling.

This meter is purchased by utility distributors, industrial facility managers, and energy service providers in regions implementing time-of-use billing. Buyers commonly specify it for retrofits in older metering systems requiring modern data capture and remote reading. Packaging is typically in cartons of 10 units, with bulk orders accepted. Lead time and Incoterms must be confirmed directly with the supplier, as they vary by order volume and destination port.

Feiyue United Technology Group Co., Ltd is located at Feiyue Building, Jieda Road, Liushi, Yueqing, Zhejiang, China. The supplier is identified as an imported tier with harbor trust verification, indicating shipment history and export compliance. The listing shows no response rate or average response time, suggesting limited buyer engagement or automated communication. The company does not state its years in business, employee count, or client list, and no certifications beyond product standards are referenced.

The supplier specializes in electronic metering products, with the DEM031 being the only model detailed in this listing. No other product lines, R&D facilities, or quality management systems are mentioned. The absence of response metrics and detailed company history implies a manufacturing-focused exporter without dedicated sales infrastructure. Buyers should treat this as a direct factory source with limited post-sale support unless otherwise confirmed.
