LINETRAXX® CMS460-D

LINETRAXX® CMS460-D

The CMS460 system consists of one or several CMS460-D load current evaluators which are able to detect and evaluate load currents in earthed and unearthed power supplies via the associated measuring current transformers. The maximum voltage of the system to be monitored depends on the nominal insulation voltage of the measuring current transformer used in the case of busbar systems, or on the cables or conductors that are routed through.

CTAC… (closed), WR… (rectangular) and WS… (split-core) and WF… (flexible) measuring current transformers are used for alternating and pulsating currents. Any combination of the various measuring current transformer series can be connected to the evaluator measuring channels. Each CMS460-D utilises 12 measuring channels. Up to 90 load current evaluators can be connected via a BMS bus (RS-485 interface with BMS protocol), thereby up to 1080 measuring channels (sub-circuits) can be monitored.

If this product is to be used for fire or plant protection, the frequency response can be set accordingly. The measured currents can be analysed for harmonics.

Features

  • Optional AC or pulsed DC sensitive measurements for each channel
  • r.m.s. value measurement
  • 12 measuring channels per individual device for load current
  • Up to 90 evaluators CMS460-D in the system (1080 measuring channels)
  • Fast parallel scanning for all channels
  • Response ranges 100 mA…125 A (42…2000 Hz)
  • Preset function
  • Adjustable time delays
  • Adjustable frequency behaviour (e.g. fire and plant protection)
  • History memory with date and time stamp for 300 data records/channel
  • Data logger for 300 data records/channel
  • Analysis of the harmonics, THD
  • Two alarm relays with one changeover contact each
  • N/O or N/C operation and fault memory selectable
  • Connection external test and reset button
  • Backlit graphical display (7-segment display) and alarm LEDs
  • Data exchange via BMS bus
  • Password protection for device setting
  • RoHS compliant

Applications

  • Monitoring of loads and installations for load currents in the frequency range of 42…2000 Hz (measuring current transformers CTAC…, WR…, WS…, WF…)
  • Monitoring of currents regarded as fire hazards in flammable atmospheres
  • EMC monitoring of TN systems for “stray currents” and additional N-PE connections
  • Monitoring of N conductors for overload caused by harmonics
  • Monitoring of PE and equipotentional bonding conductors to ensure they are free of current
