Circuit monitoring systems

A new level of efficiency and availability
  

Circuit monitoring systems (CMS) is a unique ultra-compact and high-performance multichannel measurement system for branch monitoring. The system consists of control unit and sensors with different measurement ranges and mounting possibilities. CMS range is specifically designed to meet the requirements for power monitoring and energy efficiency analysis in buildings and critical power applications.

New control unit CMS-700 enlarges the portfolio of central units for energy and power circuit monitoring. Through the built-in web server, CMS700 allows easy access for data collection, analysis and download to optimize energy efficiency analysis of power consumption, and power management of the system in order to always guarantee uninterrupted power supply and service to customers. All CMS central unit can be remotely queried via different options of communication protocols interfaces.

CMS sensors measure any kind of current - direct, alternating or mixed - in a wide measuring range of up to 160A. The new open-core sensor generation, which represent an innovative and highly perceived quality solution, allows retrofitting of existing installation and guarantees maximum flexibility and installation in retrofit installation and to optimize maintenance operations.

 

 Main Benefits     

  • Minimize downtime in the system – Maximize running hours and productivity, avoid downtimes and connected penalties by monitoring of power availability through early detection of any deviations in power consumption at branch level
  • Assets preservation - Early detection of any deviations in power consumption at branch level, avoid before serious damage occurs in the system
  • Energy efficiency - Consumption optimization and cost saving can be performed in the system thanks to maximum transparency on where and how the electricity is used up to lower branches
  • Maximum security - Thanks to the most secure communication protocols built-in in the CMS central units
  • Easy Installation and configuration - Save up to 30% installation time thanks to smart configuration and quick installation guaranteed
  • Easy selections - Optimization of the portfolio and product selection thanks to sensor able to measure AC, DC or mixed currents

Main Features

  • Individual circuit monitoring with energy and power monitoring at branch levels
  • Minimal space requirements - Due to the compact sizes of the sensors there is no additional space needed in the enclosure
  • User-friendly commissioning – Within a few minutes, a branch monitoring system is installed and commissioned without rearranging the existing installation or interrupting the power. Open core sensors allows retrofitting in existing installations
  • Scalable - which means that the user can freely choose the number of measurement points he needs
  • Easy installation - All components get linked over one flat cable which saves installation time and leads to an excellent overview in the distribution unit
  • Flexible - Could be used in all kinds of applications up to 160 A AC/DC per each branch
  • Product always updated to latest version thanks to upgradable firmware in CMS700

Product overview

CMS sensors

Small size, huge performance

CMS sensors, 18 or 25 mm wide, are among the most compact and high-performance current sensors on the market. They enable extremely accurate and effective measurements and are flexible for any kind of installation thanks to the opportunity of measuring in only one device AC, DC or mixed currents up to 160 A (TRMS). 

The sensors can be mounted on all DIN rail components, SMISSLINE components or directly secured to the cables, minimizing the cabling the in the distribution cabinet.
Even all S800 devices with cage terminals is covered by dedicated part of solid-core current sensors portfolio. 

Measurement data are transmitted digitally via the CMS-bus interface from each sensor to the control unit. This reduces the number of cables into the distribution units and maximizes the security of the transmitted measurement values. 

The possibilities offered by the system enlarges thanks to the new open-core sensors, able to provide fast and easy installation without power interruption thanks to their U-shape design. The retrofit of existing installation and a faster cabling are guaranteed by using them, that can be installed without power interruption and special tools required.

 

CMS control unit

Measure and operate smarter

Control units are needed to process the data from CMS sensors, supply the CMS sensors with power, get access to the measurement data locally or remotely and to do all the system configurations. The number of sensors that can be connected depends on the type of control unit: up to 64 sensors with CMS600 and 96 with CMS700. The contactless measuring process rules out potential sources of error right from the start. The negligible amount of wiring required ensures maximum system stability.

The CMS-600 system enables simple and fast operation; the Control Unit is equipped with an illuminated touch display that makes not only initialization but also control of the sensors extremely simple. A 2-wire RS485 Modbus RTU interface enables users to remotely query and process the measurement data.

Trough CMS700 the data acquirements is improved, enabling energy and power measurements in the main circuit the device is monitoring, and calculating that in every branch connected. Protocols for communications include Modbus RTU, TCP and SNMP v1, 2 & 3, guarantying through the new encrypted version utmost data security. Through the built-in web server, CMS700 allows easy access for data collection

 

CMS connection technology

Easy cable assembly

To connect the sensors to the control unit a flat cable and insulation displacement connectors are needed. The cable assembly is very easy. The insulation displacement connectors can be connected by applying a small amount of pressure to the flat cable - quick, easy and reliable.

A wide range of cable is now available (up to 30 m length, with available predefined length of 2m, 5m, 10m, 30m) enabling high flexibility in any application just selecting the right component needed in the specific application.
