DC Motor Speed Control

& Fan Speed Control Products


Over the past 2 decades, Control Resources has become one of the leading OEM control suppliers of DC motor speed control and fan speed control products to the electronics, telecommunications and HVAC industries. Control Resources offers the SmartFan line of off-the-shelf and custom motor, pump and fan speed control product applications.

SmartFan DC motor speed control and fan speed control products regulate speed based on temperature (thermistor), control signal (PWM or DC) or I2C communication link. Temperature alarms and fan failure alarms are available on many models. Complete custom control design and manufacturing services are available to provide you with the optimum solution for your application.

Here are our standard DC motor speed control and fan speed control products for telecommunication, medical and commercial OEM control applications using 12, 24 and 48 VDC power.

Benefits of DC motor speed control and fan speed control

Benefits of using SmartFan DC motor speed control and fan speed control include acoustical noise reduction, engergy savings, environmental (humidity, temperature, pressure, flow) regulation, greater system reliability and improved safety.

Applications for DC motor speed control and fan speed control

DC & AC Controls for electronics cooling applications fan controls for telecommunications
Electronics Cooling

All of Control Resources' DC & AC Controls can be used in electronics cooling applications for fan speed control to regulate temperature and reduce acoustical noise. Typical OEM applications include file servers, ATE products, storage subsystems, medical devices and telecommunications equipment.
Medical Instruments & Power Supplies
The SmartFan Wisp is a temperature based fan speed control and temperature alarm circuit contained in a 1/2"D x 3"L probe that can be mounted in the exhaust or inlet of any heat producing equipment. For controlling multiple fans, low air volume applications or unusual fan types, the Wisp is a cost effective choice.
 
Telecommunications Equipment

Control Resouces specializes in fan speed control for telecommunication applications. The SmartFan Multi SD, Multi SR, Vortex, and Fusion were specifically designed for telecommunications cooling applications. Features available with the Multi SD, Multi SR, Vortex, and Fusion include:
  • Accepting diode OR'd dual power feeds from 10 to 75 VDC
  • Soft start and current limiting
  • Speed control for 12, 24, or 48 VDC fans
  • Speed control based on temperature (thermistor), PWM DC signal or via a serial communication (I2C) bus
  • Multiple programmable alarm and fan status outputs
  • Voltage boost circuit that will maintain required voltage to the fan even when the supply voltage drops below what is needed
  • Managed or intelligent FRU ATCA compliance
  • approved
  • certified
