SmartFan Wisp II Fan Speed ControlOperation/Installation Manual
SmartFan Wisp II is designed for small DC fan speed control applications and includes both a temperature control and sensor circuit packaged in a probe for convenient remote or on-fan mounting. The controller uses a linear operating principle, applying a smooth DC voltage to the fans. It is available for both Closed-Loop (temperature regulating) and Open-Loop (temperature compensating) applications. The controller’s power rating is sufficient to control up to three typical 120 mm fans.
Wisp II accepts an 11.5 to 30 VDC supply voltage range for controlling 12 and 24 VDC fans. The Wisp II design allows maximum flexibility for special applications including on-off capability, 48 VDC operation, temperature alarm, and custom control parameters. Contact CRI customer service for details.
In addition to the standard line of SmartFan controls and alarms, Control Resources also provides custom control design and manufacturing services to provide you with the optimum cooling solution for your OEM control applications.
