Orion Fans Now Shipping Tachometer Output Fans From Stock
LAS VEGAS, NV (May 6, 2008) - Providing an alternative to long lead times for custom function fans, Orion Fans is now stocking significant quantities of more than 12 models of its popular DC fan models with a tachometer output feature, giving them the ability to deliver volume orders directly from stock. The fans include models ranging in size from 25mm to 172mm.
"More of our customers are requiring the tachometer output option on DC fans because they need to be able to monitor the fan performance in their electronic enclosures, and trigger an alarm or indicator if the fan speed falls below a certain RPM," said Kevin Knight, Marketing Manager for Orion Fans. "We, along with many of our distributors, offer the tachometer output option as well as other special function iterations on more than 12 different DC fan models from stock."
Designed to provide a square-wave frequency equal to 2 periods per revolution, the tachometer output enables the design engineer to monitor and report the fan's rotational speed as well as trigger an alarm signal to indicate that the fan has stopped or slowed significantly. The tachometer output option is available as either a 5V TTL signal or as an "open collector" signal, and is available in combination with rotation detection alarm signal options, thermistor speed control, PWM control functions, or temperature sensor controls.
All Orion Fans are UL/cUL, TUV, VDE and CE approved. Their DC fans are suitable for a wide range of applications, including industrial controls, servers, telecommunications, computer equipment, motor drives and cabinets, electronic enclosures and panels. Orion will also provide additional customization or value added services depending on customer requirements.
JIT delivery programs are available worldwide.
