The ebm-papst TMS is a fan speed controller with alarm functionality providing intelligent control of up to four fans based on the thermal requirements of connected equipment. It is highly configurable and a range of fan types may be used, each fan may be set for a different speed/ temperature profiles with further configurable alarm actions.

The ebm-papst TMS fan speed controller is designed for use with ebm-papst DC compact and centrifugal fans having four wires (PWM speed setting and tachometer output variants) and can also be used with 230V EC fans if a TMS power supply is provided.
