Compatible with PWM controllers, offers all-in-one intelligent operation to lower system costs, improve reliability; manufactured in compliance with RoHS Pb-Free materials/processes
Sunon, Inc., offers internal methods to control fan speeds according to ambient temperatures. Benefits to users are immediately realized, 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 starting at 10K EAU volume requirements in typical 500 lots, in sizes from 40mm x 40mm frame size x 15mm depth up to 120mm x120mm frame size x 38mm depth. For smaller sizes, contact the factory sales representative.
The thermal controlled fans come 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 to 35°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 switching the power on and off very rapidly. Sunon’s proprietary design allows combined thermal and PWM control for maximum flexibility.
Gene Miltimore, Director of Sales and Marketing, stated, “We have provided a number of our customers with a high technology solution for advanced thermal management”. He further commented, “Having a local, US based engineering lab enables us to rapidly respond to customer specific design requests.”
The options include models featuring Sunon’s highly acclaimed MagLev® technology which is credited for its superior performance features such as low noise, high temperature endurance and super long life. Wiring and connector harnessing can be ordered for circuitry interface and simple installation. All models are manufactured in compliance with RoHS Pb-Free materials and processes to meet global expectations for environmental responsibility. MagLev models also feature all-plastic manufacture of major items for optimal insulation resistance and electrostatic discharge (ESD) performance.
