Description
Product DescriptionThe DDS7178 Series Single-Phase Electronic Kilowatt-Hour Meter is a highly reliable, compact utility meter designed for accurate sub-metering of electrical energy consumption. Engineered for single-phase two-wire AC networks, this meter utilizes advanced microelectronics and digital sampling technology to measure active power consumption with Class 1.0 precision accuracy.Available in both digital LCD and traditional analog cyclometer display variants, it features a standardized, space-saving DIN-Rail mounting design that snaps effortlessly into standard consumer units and breaker panels. It is the ideal solution for landlords, commercial property managers, and facility operators needing to track individual power usage seamlessly.Key Features:High-Accuracy Sub-Metering: Provides Class 1.0 measurement standards to accurately track active energy consumption ($kWh$).Space-Saving DIN-Rail Design: Standardized 35mm DIN-rail mounting makes installation inside electrical enclosures quick and neat.Low Power Consumption: Engineered with internal circuitry that consumes minimal overhead power during operation.Durability & Security: Housed in a flame-retardant, high-impact ABS enclosure equipped with terminal seal covers to prevent tampering.Compatible Machinery & ApplicationsThis kilowatt-hour sub-meter is universally compatible with standard electrical infrastructure and is designed to measure the consumption of single-phase electrical loops.1. Electrical System RequirementsVoltage Compatibility: Standard single-phase AC setups (typically 220V / 230V / 240V at 50Hz or 60Hz).Current Rating: Supports typical residential and commercial loads up to 5(60)A or 10(40)A depending on the specific model configuration.Mounting Infrastructure: Snaps directly onto standard 35mm DIN Rails inside distribution boards or breaker boxes.2. Common Applications & Machinery It MonitorsRental Properties & Boarding Houses: Installed in sub-panels to monitor individual electricity consumption for tenants, apartments, granny flats, or rented rooms.High-Consumption Appliances: Dedicated to tracking the power draw of heavy-duty machinery such as:Central air conditioning units and heat pumpsCommercial refrigeration compressors and walk-in freezersHigh-power workshop machinery (e.g., air compressors, table saws, welding stations)Electric vehicle (EV) home charging portsIndustrial & Server Enclosures: Ideal for monitoring power usage effectiveness (PUE) inside individual IT server racks or modular equipment enclosures
