Hi to all I bought an halogen transformer-less PS it's very small (6cmx4cm) it's have 2 transistor some capacitors and some resistors and small output transformer. as it look to me it's a step down inverter from mains 220v to 12v 32khz ac 60w output. can I connect a rectifier bridge just to get 12v dc (+-5A???) ? does the high frequency important for regulating? can I get electric shock from the 12v or its isolated cause the output transformer? if I am misunderstand I will draw it's circuit and send over the list. your answers will be appreciate Tal -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
