AVT1465 A

Halogen bulbs are relatively easy to destroy when switched on, because they then draw a very high current (even several times greater than the rated one). This causes the filament to burn out and the entire element has to be replaced. This situation can be avoided by using the presented set. Its operation consists in a short-term limitation of the current flowing into the halogen at the moment of its switching on. As an executive element, high power MOSFET is used. Because the system works very briefly, the power lost in the transistor is relatively small so that the element does not need a heat sink. The whole switch is assembled on a small plate and easily fits directly next to the halogen bulb holder.

The device is especially recommended for all users of halogen lighting

Selected parameters:

• for halogen lamps for 6 and 12V voltage
• maximum power of the protected 50 W bulb (depending on the elements used)
• no heat sink
• power supply - 6-12V
• dimensions of the plate 23x22mm
• printed circuit board and documentation included
  A version with a set of components for self-assembly is available
