Current Transformer Rogowski Coils

The CTH01 Smart Power Monitor Hub is a high-performance, multi-channel device designed for the collection and analysis of electrical parameters. Supporting simultaneous acquisition of 12 current channels and 3 voltage channels, coupled with high-precision computation, the CTH01 delivers a comprehensive set of electrical parameters including power, energy, power factor, harmonic distortion, and voltage three-phase unbalance. Featuring LoRaWAN® wireless communication and Bluetooth for local configuration, CTH01 integrates seamlessly into energy management systems, providing reliable data to support energy savings, preventative maintenance, and cost allocation.

CTH01 is engineered for commercial buildings, industrial plants, data centers, and multi-tenant apartments to enable precise energy consumption measurement, power quality monitoring, and equipment operational analysis for critical circuits within electrical distribution systems.

Technical Specifications

Comprehensive & Accurate Monitoring

• Provides high-precision measurement of active, reactive, and apparent power and energy, integrated with power quality analysis functions such as Voltage/Current THD and voltage three-phase unbalance
• Compliant with IEC 62053-21/23 standards to ensure professional measurement
• Support external wire temperature sensor for cable temperature measurement

Flexible Configuration & Deployment

• 12 current channels can be independently configured for single-phase use, grouped into 4 three-phase circuits or mixed usage
• Supports mixed use of split-core Current Transformers (100A/300A/500A/1000A) and 4000A Rogowski coils (coils must be consistent within a group)
• Provides convenient voltage measurement through direct connection via voltage measurement terminals or an optional non-invasive magnetic attachment, enabling flexible installation
• Complete parameter setup, data reading, and current direction calibration can be performed remotely via the Bluetooth-connected Toolbox APP, eliminating the need for physical access

Industrial-Grade Reliability & Storage

• 6-8kHz sampling frequency ensures data measuring accuracy
• Stores periodic data records, event logs, and up to 12 months of monthly maximum/minimum values and energy totals
• Supports user-defined threshold alarms and device-initiated overload/out-of-range alarms

Powerful Expansion & Integration

• Built-in LoRaWAN® protocol for seamless integration with Milesight Development Platform and third-party platforms
• Supports Firmware-Update-Over-The-Air (FUOTA) updates for feature enhancements
