Modules & Advantages

feature

Scalable Multi-Circuit Monitoring

Large-Scale Coverage: A single system can monitor over 30 individual circuits, making it perfect for high-density load environments like telecom towers.
Advanced Communication: Uses a specialized DC-PLC internal protocol for stable and efficient data transmission between modules.

Smart & Compact Design

• 1:1 Modular Ratio: Designed to match the width of standard circuit breakers (18 mm to 72 mm) for a clean and organized cabinet layout.
Integrated CTs: Current transformers are built directly into the module, eliminating the need for external CT wiring and saving significant installation space.
Full Specification Support: Available in M10, M20, M30, and M40 models to support 1P, 1P+N, 3P, and 3P+N load types.

Must be paired with a Enertrek V10

•Complete Measurement: While the M module collects current, it requires the V module to calculate energy and monitor the operational status of electrical equipment for both single-phase and three-phase systems.
→Voltage measurement accuracy: 0.2%
→Voltage Harmonic (THD) analysis, up to the 63rd harmonic
•System Architecture: In a typical setup, a single V module can support and monitor over 30 multi-circuit M modules.
•Power & Data: The modules connect via the Enertrek BUS (RJ12) to share power and communication (RS485 Modbus-RTU) across the system.

High-Precision Measurement

• Revenue-Grade Accuracy: Achieves Class 0.5 accuracy for active energy and Class 0.2 for current measurement, ensuring reliable data for billing and analysis.
• Comprehensive Data: Monitors a wide range of parameters, including Uab, Ubc, Uca, Va, Vb, Vc, and f.
• Wide Range: Supports a base current of 10A with a maximum capacity of up to 63A.

Rapid "Plug & Play" Installation

• Enertrek BUS (RJ12): Modules connect quickly via RJ12 interfaces, providing both power and communication through a single cable to reduce labor time.
• Flexible Mounting: Supports DIN rail mounting or direct attachment to the upstream or downstream ports of protection devices.
• Snap-on Mechanism: Features an internal buckle structure for secure and fast cable attachment.
