Product Details

Description



Features:

• Choose 12, 24, or 48 VDC nominal voltage ratings
• High power 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)
• Selectable Control Temperatures of 35°, 40°, or 45°C (74°, 80°, or 86°C when P3 sensor is used)


Description

012D440 is a versatile switching DC control which operates at a highfrequency 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 Temperature is set by means of a jumper on the circuit board. 012D440 is supplied with an optically isolated temperature alarm, triggered if sensor temperature reaches 10°C above Control Temperature or if cooling system power is lost.
