Overview
Maximize Your Panel Density. Unleash Precision Energy Tracking.
KEYPLUS M-Series Smart Power Monitoring Module (M10 / M20 / M30 / M40)
The KEYPLUS M-Series is a high-density, multi-circuit power monitoring sensor designed for next-generation AIoT electrical infrastructure. Featuring an innovative wire pass-through design with built-in CTs, it delivers Class 0.5 metrology-grade precision for currents up to 63A. Designed for rapid plug-and-play scaling via an RJ12 daisy-chain bus, it eliminates conventional cabinet clutter across data centers, telecom base stations, and high-density commercial panels.
Pain Points & Challenge
Are Cluttered Wiring and Blind Spots Compromising Your Power Grid?
- Bulky CTs & Cable Bottlenecks: Traditional power meters rely on external current transformers and secondary wire harnesses, making comprehensive branch monitoring virtually impossible in tight server racks and telecom enclosures.
- Inaccurate Telemetry & Hidden Thermal Risks: Coarse-grained energy metrics combined with an absence of branch-level thermal tracking leave facility teams blind to abnormal heat accumulation, leading to unexpected outages and electrical fire hazards.
Key Capabilities & Benefits
Ultra-Compact Wire Pass-Through Design (High-Density Expansion)
- Feature: Integrated solid-state CTs built directly into a compact pass-through housing, available in 1P (M10), 2P (M20), 3P (M30), and 4P (M40) forms for branch loads up to 63A.
- Advantage: Completely avoids external CT mounting brackets and cuts internal cabinet wiring bulk by over 70%.
- Benefit: Scales branch circuit telemetry inside space-restricted distribution boards effortlessly, reducing installation hours and hardware overhead.
Seamless RJ12 Plug-and-Play Architecture
- Feature: Utilizes a unified RJ12 bus daisy chain to cascade modules directly to the central Voltage Unit (V10), enabling automated hardware addressing and commissioning.
- Advantage: New monitoring nodes connect in seconds without manual address dip-switching, circuit redesigns, or service downtime.
- Benefit: Delivers true zero-downtime scalability for ongoing expansion projects, making maintenance and retrofits fast and mistake-proof.
Metrology-Grade Accuracy with Thermal Monitoring
- Feature: Delivers Class 0.5 measurement accuracy across full electrical parameters (L, P, Q, S, Power Factor, Active Energy) paired with integrated thermal sensing.
- Advantage: Simultaneously measures granular power consumption and tracks real-time temperature increases across each monitored circuit.
- Benefit: Provides audit-proof data for tenant sub-billing and carbon accountability, while serving as a frontline preventive defense against thermal overload and fire hazards.
