No need for a dedicated power supply with new temperature fan speed controllers

The ebm-papst DCP temperature controller offers closed loop, temperature sensitive speed control for the ebm-papst four-wire PWM-controlled DC fans. The controller voltage is matched to the fan so, with its extremely low power consumption, there is no need for a separate, dedicated power supply. The controller controls fan speed between 0% and 100% against a pre-programmed temperature profile and also incorporates a combined fan fail, sensor fail and over-temperature alarm.
