New fan controllers deliver temperature-sensitive fan speed control

RS Components offers new energy-efficient fan controllers together with the 4300N series of fans from ebm-papst. The latest fan controller solutions are low-cost, credit-card-sized devices. The DCP controllers offer optimised power consumption by giving temperature-sensitive speed control for four-wire PWM controlled compact fans at 12, 24 and 48VDC. The EC range allows temperature control for compatible fans fitted with energy-saving motors. Both ranges provide a choice of pre-set temperature profiles and are supplied with a 2m temperature sensor lead, allowing a set of alarm functions such as over-temperature, fan and sensor failure, all without the requirement for an additional power supply to operate them. This latest generation also includes the brand new CGC, which is suitable for both DC and EC fans and allows customers to adapt temperature profiles, making them ideal for use as a development kit.
