These are variable voltage, universal, AC to DC power supplies with selectable DC voltage from 3 to 12 V DC The units plug into a standard US 110/120V AC receptacle and provide manual speed control for all of our products Speed is adjusted by varying the voltage and the normal operating range of the cooling and ventilation products is 7 to 9V for most applications or 12V for more demanding and aggressive situations

The DC end of the power supply utilizies a 2-pin female receptacle on the end of a 4' cord The receptacle plugs directly into most products The power supplies come with several plugs that are color coded but due to inconsistencies in the color coding, find the plug that fits the best - the correct plug will simply fit snuggly into the DC jack on the fan product You can also check the packaging as coding should be indicated correctly on the actual package that you receive

When using the plug, ensure to align 'Tip' to '+' on the ends of the connectors/plugs If reversed, the units will not be damaged but they simply will not work

Technical Notes

  • Hot Power Supply Power supplies do get warm in normal applications, however, if the unit gets too hot, you should unplug it and get a larger power supply (more milliamps) as the power supply may be overloaded
  • Tesing the Unit These units, when not under load, will read between 14 and 18V DC on a voltmeter This is a normal and expected reading no matter the voltage selected on the power supply
