Halogen Continuous
Problem with 13.8v transformer – power supply to 12v halogen lamp?
I have a 13.8 volt regulated DC power supply (Maplin) which gives 5A continuous, 7A 50% duty cycle and 9A surge.
I have connected this directly to a bulb holder to power a 12v 50W halogen 6.3 bulb.
The problem I am having is that when I switch the power on to the transformer and light that nothing happens, but if I then remove the connecting wire to the transformer from the light and tap it on the terminal a few times it starts to work and stays on for however long. This happens every time.
The circuit is very simple and has been tested, the transformer is kicking out 13.8v so I thought it could be a faulty diode in the transformer that cause the problem. But, today I got it exchanged with Maplin for a brnad new one and the same problem exists.
Any ideas as to what could be causing this?
Many Thanks
Your transformer is intended as a car battery charger and not for passive loads like a lamp. My guess is there is some active circuitry in the box that is determining the charge on the car battery and the lamp is confusing it.
It is possible that a high value capacitor in parallel with the lamp may trick the charger. Worth trying if you have such a capacitor, but don’t go out and buy one.
