Fan controllers deliver temperature-sensitive speed control

The EC range offers temperature control for compatible fans fitted with energy-saving motors.

Both ranges offer a choice of pre-set temperature profiles and are supplied with a 2m temperature sensor lead, enabling a set of alarm functions such as over-temperature, fan and sensor failure, all without the need for an additional power supply to operate them.

This latest generation also includes the brand new Configurable Generic Controller (CGC), which is suitable for both DC and EC fans and enables customers to adapt temperature profiles, making them ideal for use as a development kit.

Also available from RS is the 4300N series of DC axial fans, which offers high airflow (up to 285m³/h) with low operating noise and high efficiency. 

The 119 x 119 x 32mm series features improvements such as specially formed discharge vanes and innovative winglets on the blade tips to improve the aerodynamic efficiency and prevent turbulence that can cause noise. 

More specialised versions are also available that offer speed signal output, PWM input, moisture protection, IP68 protection and external temperature sensor.

This enables the fans to target a range of industries and applications including computing and telecommunications, drives, automation, solar inverters, as well as automation and a wide selection of other industrial applications.

The ebm-papst 4300N series of DC axial fans and fan controllers are now shipping in the EMEA and Asia Pacific regions.
