CTH01
The CTH01 turns a distribution board into a source of billing-grade energy data: twelve current channels and three voltage inputs measure active, reactive and apparent power and energy, power factor, harmonic distortion and three-phase voltage unbalance, to IEC 62053 accuracy (±1% active energy). Channels can be assigned as twelve single-phase circuits, four three-phase groups or a mix, using split-core CTs from 100 A to 1,000 A or 4,000 A Rogowski coils. It clips onto a DIN rail, is set up from a phone over Bluetooth, holds 12 months of statistics and reports over LoRaWAN Class C. Typical uses include tenant cost allocation, data-centre circuits and preventive maintenance.
