Macey Controls have developed a number of units specifically for use with EC Fans some are set out in this brochure.

This basic Speed Control module provides a economical method to provide a variable voltage to the speed control input of EC Fans. 

This module allows remote monitoring of one or two fans. It provides a set of voltage free relay change over contacts which operate if a fan fault is detected or loss of supply power.

This module allows remote monitoring of up to 4 EC fans. It uses the Tacho output of the EC Fan/s. If any fan/s drop below a pre-set RPM then a fault output is generated. Fault conditions are given out by a solid state relay and on board LED indication for each fan. 

This module allows remote monitoring of up to 5 EC fans. It uses the Tacho output of the EC Fan/s. If any fan/s drop below a pre-set RPM then a fault output is generated. Fault conditions are given out by voltage free relay contacts,
