Milesight CTH01 | LoRaWAN 12-Channel Smart Power Monitor Hub

The Milesight CTH01 is a high-performance, multi-channel smart power monitor hub that collects and analyses electrical parameters across many circuits at once. With 12 current channels and 3 voltage channels and high-precision computation, it delivers a full set of metrics - power, energy, power factor, harmonic distortion and voltage unbalance - to IEC 62053-21/23 standards. It reports over LoRaWAN and configures locally via Bluetooth (ToolBox app), integrating into energy-management systems for energy savings, preventative maintenance and cost allocation. Designed for commercial buildings, industrial plants, data centres and multi-tenant sites, it measures consumption, power quality and equipment behaviour on critical circuits. Key Features Multi-Channel Metering12 current channels and 3 voltage channels measure active, reactive and apparent power and energy across single- or three-phase circuits. Professional AccuracyActive energy ±1% (IEC 62053-21) and reactive energy ±2% (IEC 62053-23), with THD and three-phase unbalance analysis. Flexible CT OptionsMix split-core CTs (100/300/500/1000A) or 4000A Rogowski coils, with direct or non-invasive magnetic voltage pickup. Connected & CapableLoRaWAN reporting, Bluetooth ToolBox setup, FUOTA updates, threshold/overload alarms and on-board data storage. Typical Applications •Commercial buildings & data centres: sub-meter many circuits for energy and cost allocation. •Industrial plants: monitor power quality (THD, unbalance) and equipment health on critical feeds. •Multi-tenant sites: measure per-tenant consumption from a single distribution-board hub.
