Smart Fan products family offers internal methods to control fan speeds according to ambient temperatures. Fan operation is thermally controlled to meet cooling needs vs. continuous operation. This reportedly enables longer operating life, lower noise and reduced cost of operation. Applications include computers, peripherals, servers, power supplies, workstations and telecom equipment.
 
Offers a variety of sensor technologies provided within the immediate fan housing. These range from thermistors to Hall Effect sensors to Chip-On-Board thermal controller devices. Available for volume requirements in sizes from 40 x 40 x 15 mm to 120 x120 x 38 mm.
 
Has linear ramp control, featuring two temperature set points (no limit). Optional switch function provides programmable temperature-based control for turn-on/turn-off (such as turning off when temperature falls to 35°C, etc.).
 
Options include: 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.
 
Series includes models featuring MagLev technology. Wiring and connector harnessing can be provided for circuitry interface and simple installation. Manufactured in compliance with RoHS Pb-Free materials and processes. MagLev models also feature all-plastic manufacture of major items for insulation resistance and ESD performance.
