The input transformer is likely to be the most expensive part of the entire project. As an alternative, a couple of 12 Volt car batteries could be used. The input voltage to the regulator must be at ...

This 12 Volts transformerless power supply take advantage of the fact that a Zener diode is also a normal diode that conducts current in the forward direction. During one half wave, the current flows ...

The LDB200 series of LED power supplies from Excelsys offer 200 Watts of constant current / constant voltage power in an IP67 rated, low profile, aluminum case measuring only 7.80 x 2.48 x 1.38" with ...

The eDriver family of LED power supplies are available in a broad range of constant voltage and constant current drivers. The eDriver family of LED power supplies are available in a broad range of ...

Light emitting diodes (LEDs) are low-voltage light sources that require a constant DC voltage or current to operate optimally. Because they operate on a low-voltage DC power supply, they easily adapt ...
