Omni SD-DC — Speed control for DC fans

martFan Omni SD is a versatile switching

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.

FEATURES

• Choose 12, 24, or 48 VDC nominal voltage ratings

• High pow er efficiency: typically greater than 90%

• Noise reduction: typically 15 dB(A) or more

at idle speed

• Constant idle voltage regardless of input voltage

• Optically isolated temperature alarm output sinks

up to 1.0 mA (normally closed)
