Switching Power Supplies & AC-DC Units

AC-DC switching supplies convert the incoming supply to the DC output needed by equipment. Begin with the required output voltage and total load current, then choose a unit with the right input range and mounting arrangement.

Constant-voltage supplies and constant-current LED drivers are different types even when their power ratings are similar. Read the output specification before substituting one. For DIN-rail Omron models, see S8VK power supplies.
