Want to keep a closer eye on your electricity use? This single-phase energy meter is a handy little device for that. It's model DDS015, designed to measure active energy consumption for standard 230V, 50Hz AC power (common in many households). It handles a wide current range from 5 up to 80 Amps, so it can monitor everything from a single appliance to a good chunk of your home's power. Mounts easily on a standard 35mm DIN rail in an electrical cabinet. The backlit LCD screen shows you two things: your total energy used (which you can't reset) and a separate count you can clear to track usage over a specific time - like for a billing period or to test a device. It's built with SMT tech for stability and resists interference, plus it's tough enough for temperatures from -25°C to 55°C. The green light shows it's powered, and a red light flashes with energy pulses. Great for homeowners curious about usage, landlords managing rental properties, or even for checking how much power a workshop tool or server rack is drawing. It's accurate, has anti-tamper features, and its compact size (about 100x68mm) fits neatly. A practical tool to understand and potentially reduce your electricity bill!
