Description
Product Description The DDS7178 Single-Phase Digital Kilowatt-Hour Meter is a highly precise, electronic sub-meter designed for tracking active electrical energy consumption in individual electrical circuits. Featuring a clear, backlit digital LCD interface, this meter accurately samples voltage and current to calculate accumulated energy usage (kWh) with Class 1.0 utility-grade precision. Engineered with a space-saving modular DIN-Rail design, it integrates seamlessly into standard consumer units, breaker boxes, and electrical distribution boards. It serves as an excellent tool for landlords, property management firms, and industrial facility operators who require precise secondary billing data or localized power consumption analytics. Key Features: Digital LCD Display: Clear, easy-to-read numeric display tracking cumulative energy consumption (kWh) that doesn’t fade over time. Compact DIN-Rail Profile: Standardized 35mm width configuration saves critical space inside electrical enclosures. Tamper-Evident Security: Features built-in terminal seal covers to prevent unauthorized access or manual wire manipulation. Low Self-Consumption: Designed with high-efficiency internal circuitry that draws negligible overhead power during operation. Compatible Machinery & Electrical Infrastructure The DDS7178 digital sub-meter is universally compatible with standard single-phase alternating current (AC) distribution systems to monitor localized energy branch loops. 1. Electrical System Requirements Grid Voltage: Fully compatible with standard single-phase AC networks (typically operating at 220V / 230V / 240V AC). Grid Frequency: Standard 50Hz or 60Hz electrical infrastructure. Wiring Setup: Traditional 1-Phase 2-Wire (1P2W) line-in/line-out configuration. Enclosure Type: Standard 35mm DIN Rails commonly found in breaker boxes and consumer panel boards. 2. Common Machinery & Appliances It Monitors This meter can be dedicated to isolate and track the power consumption of any single-phase heavy load, including: HVAC & Climate Systems: Inverter air conditioners, localized single-phase split units, heat pumps, and ventilation fans. Refrigeration Equipment: Commercial reach-in freezers, walk-in coolers, beverage display cases, and ice machines. Workshop & Light Industrial Machinery: Single-phase air compressors, dust collectors, table saws, and electric welding equipment. Property Sub-Panels: Ideal for allocating electricity costs for tenants in granny flats, retail stalls, shared office spaces, or rental apartments. EV Charging Stations: Dedicated monitoring for residential or small commercial electric vehicle (EV) home charging ports.
