Sunon Offers Intelligent Thermal Control Fan Capabilities

Compatible with PWM controllers, all-in-one intelligent operation to lower system costs & increase reliability. Sunon offers internal methods to control cooling fan speed according to ambient temperature. Benefits to users are immediately realised, where fan operation is thermally controlled to meet cooling needs vs. continuous operation. This enables longer operating life, lower noise, and reduced cost of operation. Applications considered ideal for use of these devices includes computers, peripherals, servers, power supplies, workstations, telecom equipment and other systems. Sunon’s concept offers a variety of optional sensor technologies provided within the immediate fan housing. These range from the use of Thermistors, to Hall Effect sensors, to Chip-On-Board (COB) thermal controller devices. This capability is projected to not only simplify system development processes and alleviate extra engineering and design steps, but can directly improve unit performance and reliability. Thermal controlled fans are available in axial fan and blower sizes from 40mm x 40mm x 15mm up to 120mm x120mm frame size x 38mm. Further Benefits Thermal controlled fans come as standard with a linear ramp control, featuring two temperature set points (no limit). An optional switch function also provides programmable temperature-based control for turn-on/turn-off (such as turning off when temperature falls below 25°C, etc.). The following options are also available: Delay Start – Enables fans to be hot-swapped or changed without powering down the system. Ramp Start – Prevents inrush currents, placing less stress on circuits. Current Limitation and Fan Speed Limitation – Fan runs at constant speed while operating at higher-than-rated voltage. Fan Performance Sensor (FPS) - Provides preset RPM threshold, delay, non-latching and latching functions to determine fan failures. Pulse Width Modulation (PWM) - Controls fan speed by maintaining a constant voltage but switching the power on and off very rapidly. Sunon’s proprietary design allows combined thermal and PWM control for maximum flexibility. In addition to experienced application engineers working for Sunon’s UK Agent and Distributor, Thermaco Limited, Sunon has a European engineering lab, enabling rapid respond to customer specific design requests. Added value options include wiring and connector harnessing for circuitry interface and simple installation. For more information please contact Sunon UK Agent & Distributor, Thermaco Limited.
