inteliLIGHT® FRCM-M1 LTE-M lighting panel control & monitoring unit


Installed inside the feeder pillar, it is designed to provide autonomous operation for street lighting installations and carries out three phase measurements and analysis of electrical parameters in street lighting grids.

  • Specially designed and optimized for LPWA networks.
  • VPN security with AES128/256-bit encryption and key rotation.
  • Bandwidth efficient with minimal communication requirements.
  • Autonomous operation based on prede­fined astronomic calendar and/or external light level sensor (digital INPUT).
  • Remote real-time ON/OFF control.
  • Remote monitoring of grid parameters in street lighting grids: per phase voltage, current, frequency, power factor, active/ reactive/ apparent power, daily active/ reactive energy consumption.
  • Configuration options for: current transformer ratio, voltage/power thresholds and daytime/nighttime consumption thresholds.
  • LCD for displaying electrical parameters and device status.
  • GPS for exact location and time.
  • Maintenance switch for local manual override (AUTO/ON/OFF).
  • Inputs: 2 x Digital INPUT.
  • Output: 1 x Dry contact relay output (230V, max 3A).
  • Designed lifetime: 10+ years.
