DC/AC inverters designed to light Cold Cathode Fluorescent Lamps (CCFL’s) are a very specific sub-class of inverters in general. These inverters tend to have very low output currents and very high output voltages. Since the lamps are used in signage where constant light output is needed as well as in LCD panels where variable light output is sometimes required the inverters come in several classes. Besides the single or multiple lamp classes, there are fixed output, and dimmable output variations. The fixed output inverters are very simple to set up. They have a DC voltage input, a DC voltage return or ground, a high voltage output, and a high voltage return. Applying the recommended input voltage to the inverter provides the designed output voltage. There is some variation available to the output by changing the input voltage to the inverter this is not recommended.
