PWM Electronic Fan Controller

The electronic fan speed controller is designed to be mounted on the fan, close to its motor. This minimises radiated radio frequency levels, and provides good heat dissipation from the air coming from the fan.

• Nominal supply voltage: 12V or 24V.
• Operating voltage range: 10.5 to 16V (for 12V) or 18 to 32V (for 24V).
• Rated current: 25 A (for 12V) or 15 A (for 24V).
• Reverse polarity protection.
• Operating temperature range: -40 ̊C to 85 ̊C.
• Storage temperature range: -40 ̊C to 90 ̊C.
• Over-temperature protection.
• Input signal: PWM 0÷5V.
• Output signal: PWM with variable duty-cycle.
• Diagnostic signal: motor voltage feedback.
• Overload protection.
• Motor circuit protection.
• Electromagnetic compatibility according to UNECE Regulation No. 10.
