Cool Components PS1700
Universal Transformer, Power Supply - 1700mA
The Cool Components Power Supplies 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. 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. However, operating these products between 7 and 9V provides for quieter operation of the fans while at 12V most of these products will be audible. The advantage provides the option to run the cooling products quietly when components are within close proximity of sitting areas, or more aggressively when components are tucked away in cabinetry and closets. This is when components require more airflow and when noise is not as big of a factor.
The DC end of the power supply utilizes a 2-pin female receptacle on the end of a 4' cord. The receptacle plugs directly into most of the Cool Component products but on the other products (mainly the metal, cooling units), a 2.1mm Coax plug is used. 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. 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. To determine how many units can be powered with a particular power supply, calculate the milliamps of power required for each of the products to power using one power supply. Calculate the milliamps and then select the appropriate power supply.
- Hot Power Supply: Power supplies do get warm in normal applications, however, if the unit gets too hot, 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.
