DescriptionThe PCE-SPC 20 power meter provides precise measurement and monitoring of electrical energy consumption in installations (residential, commercial, light industrial). It supports circuit analysis and real-time monitoring to help optimise energy use. The device uses two 20 A closed‑core current transformers for non-intrusive current measurement (pass conductor through CT). Voltage is measured via the device supply. From current and voltage the unit calculates power (W) and energy (kWh) and displays results clearly. The meter is designed for 35 mm DIN‑rail mounting in distribution cabinets. Measurement data are transmitted via 2.4 GHz WLAN to a mobile app (Tuya / Smart Life) for live display, storage, analysis and export. The device itself does not retain long-term trend data; values update approximately every 15 seconds.
