Description

The original EFC has evolved to a version with higher power and versatility. It now supports up to nine independent PWM fans and can supply 4.5A per header (resettable fuses) or a total max of 20A (hard fused). There are two external temperature sensor connectors (sensor cables included) plus an on-board ambient temperature and humidity sensor. It can be software controlled and monitored using the included USB cable. Both ElmorLabs software and support for writing your own code is supported, commands include reading sensor data, adjusting behavior, fan duty and display. Datasheet containing details will be released shortly.

The optional 2.4″ OLED provides a GUI for autonomous operation. Two profiles are supported in firmware, with temperature (TS1/2/AMbient), fixed or EXT_FAN modes. Easily switch between profiles by long-pressing the “+” button.

Default profile 1:

  • 50% fan speed
  • If TS1/TS2 are connected, 20% duty at 25 C linearly scaled to 100% duty at 40C
  • If EXT_FAN cable is connected, mimic the PWM signal (limit 20% – 100%)

Default profile 2:

  • 100% fan speed
