at idle speed
Constant idle voltage regardless of input voltage
Optically isolated temperature alarm output sinks
up to 1.0 mA (normally closed)
Selectable Control Temperatures of 35°, 40°, or 45°C
(74°, 80°, or 86°C when P3 sensor is used)

SmartFanOmniSDisaversatileswitching
DC control which operates at a high-
frequency to achieve maximum power
efficiency at minimum size. Units are available
for nominal 12, 24 and 48 VDC operation.
Omni SD controllers apply a smooth DC voltage
to the air mover for absolute minimum noise.
They are compatible with temperature sensors
P1 through P9 shown on page 34. Control Tem-
perature is set by means of a jumper on the cir-
cuit board. Omni SD is supplied with an optically
isolated temperature alarm, triggered if sensor
temperature reaches 10°C above Control Tem-
perature or if cooling system power is lost.
