QY2P Single-Phase DIN Rail Energy Meter LED/LCD Display 0.5% Accuracy
The QY2P series is a range of single-phase DIN rail energy meters built around a shared 0.5% high-accuracy measurement platform, factory calibrated for stable, consistent performance. Three models are available to match different display preferences and monitoring requirements — from full 5-parameter electrical monitoring to streamlined kWh-focused metering. The QY2P-E features a multi-color LED display and is the most feature-rich model in the series, measuring real-time voltage, current, active power, power factor, and total energy consumption simultaneously. It is the right choice for users who need a complete view of their circuit's electrical performance — identifying inefficient loads, checking power factor, and tracking energy costs in one device. The QY2P-UID uses a high-contrast color LCD screen and focuses on the three core metering parameters: voltage, current, and total energy consumption (kWh). Its streamlined display and cost-effective positioning make it well suited for straightforward energy usage tracking in residential sub-metering, rental properties, and light commercial circuits where power factor monitoring is not required. The QY2P-UIDY shares the same V/I/kWh parameter set as the QY2P-UID but features an upgraded color LCD with optimized layout and enhanced readability. It is the premium display option in the series — designed for installations where long-term visibility, clear digit rendering, and panel aesthetics matter. All three models install on standard 35mm DIN rail.
