G+_Rud Dog Posted June 30, 2016 Share Posted June 30, 2016 Playing around with a 9.8 DC volt motor removed from a drill motor. The brick I found in my junk box is rated at 12VDC 2.5 AMPs. Using the variable trigger from the parts acquired when the drill motor was disassembled I find the motor cuts out at certain point around 3.2 AMPS. Now I have lots of 12VDC bricks in my junk box and was wondering can I use them in a configuration similar to batteries. By that I mean can the bricks be placed in parallel and function or blow up in my face? Link to comment Share on other sites More sharing options...
G+_Eddie Foy Posted June 30, 2016 Share Posted June 30, 2016 If the bricks are linear regulated you can put them in parallel, if they are switched its a bad idea. Link to comment Share on other sites More sharing options...

G+_Eddie Foy Posted June 30, 2016 Share Posted June 30, 2016 Might say on the label. O'scope might show the HF ripple of a switching while 'freewheeling' Also the efficiency would give some idea, linears, while being 'clean' are wasteful and toss off more heat. Measuring the input current vs output would be an indication. Link to comment Share on other sites More sharing options...
