How to use the Selection Guide
Selecting the correct triple output switch-mode power supply is easy.
1.	Determine your voltage and current requirements and calculate your minimum wattage requirement. (∑ P_(watts) = E_(volts) x I_(amps))
2.	Read down the voltage columns until you reach a supply with output currents equal or greater than your requirements. Please note that where a range of output currents are given, then the output has minimum load requirements. Important Note Check that total wattage of the outputs does not exceed maximum wattage of the power supply. Refer to the manual for additional information.
3.	Check that the 'type' is compatible with your application.
4.	Click on the model number for specifications and price information.
5.	Check the model suits your application.
6.	Place your order with Computronics.
