Product Overview
The Tepsung DDS986 Class 0.5S single phase power meter is a high-performance electronic active energy meter engineered for accurate power measurement and efficient energy management in residential and small commercial scenarios. Compliant with international IEC62052-11:2003 and IEC62053-22 standards, this DIN rail residential kWh meter adopts an imported Texas Instruments dual-core energy metering chip, delivering ultra-high measurement accuracy that even captures micro-power consumption electronic meter data like household appliance standby power. With a compact 35mm DIN rail design, it features easy installation, real-time data sampling, and multi-layer protection, making it an ideal core device for energy conservation and precise power cost calculation for property managers, small business owners, and energy solution providers.
Key Features & Core Advantages
Ultra-High Precision Measurement Mechanism
As a Class 0.5S precision energy meter, it ensures an error range of ≤±0.5% under rated load (10%~100% of rated current) and ≤±1% under light load (5%~10% of rated current), far exceeding the industry Class 1.0 standard. Equipped with a 16-bit analog-to-digital converter (ADC) with a 10kHz sampling frequency, it realizes real-time voltage and current signal sampling, eliminating measurement deviations caused by signal delay and supporting accurate metering for unstable power sources with frequent voltage fluctuations.
Intuitive Display & Flexible Data Interaction
The meter is built with a 2.2-inch ultra-clear LCD screen with 3-level adjustable constant backlight and 12mm large energy data font, ensuring clear visibility in strong light or dim environments. It supports dual output modes: Modbus-RTU energy monitoring meter with an RS485 interface (adjustable baud rate 9600~115200 bps, maximum 1200m transmission distance via shielded twisted pair) for remote real-time data transmission, and one-key manual query for active energy, voltage, current, and power factor. The screen automatically records daily maximum power consumption for load analysis.
Robust Durability & 6-Level Comprehensive Protection
Adopting PC+ABS V0 flame-retardant composite material with a reinforced structure, the meter withstands 50N impact force and operates stably in -30℃~75℃ extreme temperatures, suitable for harsh environments like outdoor distribution boxes. Its built-in 6-level protection includes overvoltage (cutoff at >270V), overcurrent (1.5x rated current trigger), fast-response short-circuit protection (<0.1s), reverse wiring anti-error measurement, Class B anti-EMI, and IP42 dustproof and moisture-proof performance, ensuring long-term reliable operation.
Application Scenarios
High-End Residential & Rental House Energy Management
Ideal for high-end communities, villas, and rental properties, the meter’s micro-power consumption metering capability accurately records 5W router standby power and 10W night light consumption, helping users optimize energy habits and reduce costs. Its non-volatile memory stores tamper-proof historical data, avoiding electricity fee disputes between landlords and tenants, a key demand for property management companies.
Small Commercial Venue Power Monitoring
Suitable for supermarkets, restaurants, and office buildings, the RS485 remote monitoring function enables managers to track real-time power consumption in different areas (e.g., freezer zones, kitchens), identify high-energy-consuming equipment, and formulate energy-saving plans. For chain convenience stores, multiple meters can connect to a centralized management system for unified energy efficiency comparison and monitoring.
