Fans Offer Tachometer Output
Giving an engineer the ability to monitor and report rotational speed, Orion Fans’ DC fans trigger a 5-V TTL or an “open collector” alarm signal to indicate that they have stopped or slowed significantly. The UL/cUL- and TUV-approved devices have a 2 period-per-revolution square-wave frequency and can come with rotation detection alarm signal options, thermistor speed control, PWN control functions, or temperature control sensors. The VDE- and CE-approved fans come in models ranging in size from 25 to 172 mm and are useful in applications such as industrial controls, servers, telecommunications, computer equipment, motor drives and cabinets, electronic enclosures, and panels.
