Product Overview

LEIPOLE LP17251-6.0 is an EC Master™ intelligent dual-channel fan controller. After presetting target temperature parameters, its built-in temperature sensor collects real-time ambient temperature data of the heat dissipation area. The internal chip completes logical operation and automatically adjusts fan speed according to real-time temperature for intelligent thermal management. It supports simultaneous independent control of two separate fan groups, meeting diversified industrial cooling system intelligent control demands.

Core Product Features

  • Dual-channel control architecture, capable of driving and regulating two independent fan groups at the same time
  • PWM square wave control mode with 1KHz frequency range, matching EC fan speed regulation system perfectly
  • Built-in comprehensive multi-alarm protection mechanism: FG abnormal, KR relay abnormal, over-temperature, RD-H/RD-L abnormal status alarm
  • Complete temperature adaptation parameters with 9 matching levels for flexible customized temperature-speed curve setting
  • Stable wide operating environment adaptation, with reliable low-temperature and high-temperature storage performance
