with power quality and harmonic analyzerapparent poweractive power

Overview
CTH01 is a 12-channel LoRaWAN® power monitoring hub purpose-built for multi-circuit current monitoring, featuring non-invasive voltage measurement and industrial-grade analytics to help commercial and industrial facilities cut costs and optimize efficiency.

Key Capabilities

• 12-channel hub: monitors up to 4 three-phase circuits or 12 single-phase circuits in one compact device.
• Non-invasive voltage sensing: magnetic snap-on probes for voltage measurement (no terminal wiring or wire stripping required).
• Flexible current inputs: supports split-core current transformers (CTs) and Rogowski coils; hybrid CT & Rogowski support in one hub.
• High-speed sampling and advanced analytics: up to 6–8 kHz sampling frequency to capture harmonics, voltage unbalance and power factor anomalies for professional diagnostics.
• Pluggable RJ11 ports for CTs for fast plug-and-play installation.
• Bluetooth wireless configuration via Toolbox App for safe-distance setup and commissioning without panel access.
• Remote direction calibration to fix CT polarity errors in software and avoid costly site revisits.
• LED status/alarm indicator for instant visual feedback.
• Compact footprint and multiple mounting options: DIN-35 rail and optional magnetic mounting for space-constrained electrical cabinets.

Deployment & Compatibility

• Zero-downtime, non-invasive installation: snap voltage probes onto breaker screws and clamp split-core CTs around conductors without cutting cables or interrupting power.
• Supports mixed circuit configurations: three-phase (L1–L3 with or without neutral), single-phase (L with neutral), or mixed configurations within the same hub.
• Current ranges: standard up to 1000 A per channel; customizable up to 4000 A (supports RJ11-based CT / Rogowski connectivity).
• RJ11 plug-and-play ports and USB Type-C port for external/cable temperature sensor connection.

Connectivity & Management

• LoRaWAN® wireless transmission supporting multiple regional bands (CN470 / IN865 / RU864 / EU868 / US915 / AU915 / KR920 / AS923-1/2/3/4).
• Antenna: 1 × SMB female external connector.
• RF performance: Tx power up to 16 dBm (868 MHz) / 20 dBm (915 MHz) / 19 dBm (470 MHz); sensitivity down to -137 dBm; OTAA and ABP support, Class C operation.
• Device onboarding & remote management via Milesight IoT platform and Bluetooth Toolbox App; supports data storage and alarms onboard.

Industrial Analytics & Storage

• Measures: RMS voltage and current, power factor, active/reactive/apparent power, imported/exported active/reactive/apparent energy, three-phase voltage unbalance, THDv and THDi.
• High-speed diagnostics: harmonic detection, voltage unbalance detection, power factor anomalies for predictive maintenance.
• On-device storage & alarms: local data storage (example: thousands of entries and hundreds/thousands of alarms), threshold/out-of-range/power-failure alarms and up to 12 months of aggregated energy statistics (platform dependent).

Use Cases

• Energy monitoring and saving for large commercial facilities (identify idle loads and "dark" energy waste).
• Commercial cost allocation and tenant/area sub-metering for offices, retail and co-working spaces.
• Industrial predictive maintenance by capturing early signatures of equipment stress (harmonics, unbalance).
• Solar energy & microgrid monitoring: track imported vs exported energy for self-consumption optimization.
