Power consumption

Intelligent management of power consumption allows the Kingfisher LP-3 remote telemetry unit to be battery or solar powered. A sleep-mode current draw of less than 1mA minimises the size and cost of the required power supply.

Power consumption

Rugged design

The Kingfisher LP-3 low power remote telemetry unit is packaged in a two-part, rugged plastic enclosure which measures just 185mm (H) x 130mm (W) x 50mm (D) and houses the electronics and communication interfaces to ensure the Kingfisher LP-3 can withstand even the harshest environments.

Rugged design


The Kingfisher LP-3’s extensive communications options provide connectivity to the intelligent devices and networks used throughout today’s measurement and control systems. Kingfisher LP-3 communications options include:

  • Fibre Ethernet
  • PSTN
  • Dial-up modem
  • Serial (Fibre and Isolated)
  • HART
  • Line and radio FSK
  • Spread spectrum
  • Ethernet
  • Private line 1200 Baud

Inputs and outputs

Each Kingfisher LP-3 has a maximum of eight digital inputs, three of which can be configured as digital outputs. In addition, each unit has four analogue inputs and one analogue output.

Inputs and outputs


The LP-3 low-power RTU suits a wide range of applications including agriculture operations, environmental monitoring, gas metering, power metering and data logging. Essentially any remote application which lacks access to commercial power.
