Product Description

The CMS460-D is a multi-channel load current evaluator designed for AC systems, capable of monitoring both earthed and unearthed power supplies. It utilizes various measuring current transformers and can perform harmonic analysis for fire and plant protection applications.

Typical Applications

Monitoring load currents within a frequency range of 42 to 2000 Hz.
Detecting fire hazards in flammable environments.
EMC monitoring for stray currents and overloads due to harmonics.

Functionality

The device evaluates currents as true r.m.s. values with simultaneous scanning of all channels. It includes a preset function for setting response values and a history memory for data tracking. Harmonic analysis results can be displayed graphically.

Technical Specifications

Rated operating current: 100 mA to 125 A.
Frequency range: 42 to 2000 Hz.
Insulation coordination according to IEC standards.
Operating temperature: -25 °C.
Degree of protection: IP30 for internal components, IP20 for terminals.

Installation and Connection

The device supports various connection types and is designed for continuous operation. It can be mounted on a DIN rail and requires a power supply of AC/DC 100 to 240 V.

Specifications

The document details specifications for electrical components, including voltage types and terminal options. It lists products with article numbers for voltage ranges: 24-60 V AC/DC and 100-240 V AC/DC. For UL applications, the maximum voltage is DC 250 V/AC 250 V, 50/60 Hz.

Ordering Information

Provides details for ordering mounting frames and accessories, including power supply units and RS-485 repeaters, each with a specific article number.

Condition Monitors

Describes condition monitors with integrated gateways for Bender systems and Ethernet connections, supporting various voltage ranges. Features include individual text messaging, device failure monitoring, and alarm notifications via email. Function packages are available for Modbus TCP server, parameter setting, and system visualization.

Alarm Indicators and Test Combinations

Lists models of alarm indicators and test combinations compliant with IEC 60364-7-710 standards. They feature BMS bus and USB interfaces, programmable alarm texts, and are available in surface or flush-mounting enclosures. Different versions offer varying numbers of digital inputs and relay outputs.

Measuring Current Transformers

Lists flexible and pulsed current-sensitive measuring current transformers in various constructions (circular, rectangular, split-core) with specific inside diameters, each associated with an article number. The WF series includes a flexible transformer and an RCC420 signal converter.

Load current evaluator CMS460-D Frequency settings The frequency response of the equipment can be set for a linear frequency response (up to the maximum frequency of 2000 Hz) if used for fire protection or for a frequency response in accordance with IEC 60990. For plant protection, the load current is measured up to the rated system frequency. The figure below shows the corresponding frequency response. Frequency curves Response factor = I∆/I∆n (I∆) Response current: Measured value at which the CMS responds.
