Fan Speed Controllers
Fan Speed Controllers
Fan speed controllers use the condensing pressure to modulate the speed of condenser fans. They help to reduce fan noise level during low ambient conditions (night). Easy installation is achieved with pre-wired cable connector assemblies. IP65 protection allows outdoor mounting.
 

Electronic Fan Speed Contoller

Series FSY Fan Speed Controllers can be used for 1-phase fans with motor currents up to 4 A.
 Fan Speed Control Module Minimize noise with pressure actuated condenser fan speed control. The most economical solution for highly efficient, low energy consumption electronically commutated (EC) motors. Emerson FSE control modules are simple and economical devices that provide analogue 0…10 V electrical signals based on condensing pressure changes. They have been optimized to meet the requirements of air-cooled condensers. Additional conditioning of the output signal is not necessary.
