SmartFan
Omni SD Fan Speed Control and Alarm is
a versatile switching DC
fan speed control which operates at a high-frequency
to achieve
maximum power efficiency at minimum size. This fan speed control operates from a 12, 24 or 48 VDC supply voltage.The Omni SD fan speed control applies a smooth DC voltage to
the air mover for absolute minimum noise.
Three standard fan speed control temperature options are set by a jumper on
the circuit board. Omni SD is supplied with an
optically
isolated temperature alarm, triggered if sensor
temperature reaches 10°C above fan speed control
temperature or if cooling system power is lost.
In addition to our standard SmartFan fan speed control and alarm products, Control Resources also provides custom control design and manufacturing services to provide you with the optimum fan speed control solution for your OEM applications.
