SmartFan Multi SD
is a new generation
fan speed control and temperature alarm
designed for DC fans and blowers. By controlling
fan speed, Multi SD can regulate temperature,
reduce acoustical noise and improve reliability.
Multi SD offers features that were previously
only available on custom products. The Multi SD
includes diode ORing and fusing of dual power
feeds with a wide voltage range, jumper selectable
12, 24 or 48 VDC operation, multiple sensor inputs,
fan current limiting and a full speed over-ride input.
SmartFan products are used extensively in a
wide range of applications including file servers,
storage subsystems, telecommunications, ATE
and medical equipment.
