Ultra Low Noise Lab Power Supply
bought one of those circuit boards from Stammheim:
dual channel, 3x LT3045 regulator and currently build up a dual channel power supply (0-15V, 0-1.5A). In the first version without current limit functionality, as the necessary pin on the board is tied to ground. I created a frontpanel for a case that is based on proMa aluminium case 131030:
Universal-Gehause 168 x 103 x 56 Aluminium Natur (eloxiert) Proma 131030 1 St. online kaufen >> conrad.de
What is left is a suitable toriodal transformer, but the question is, what is suitable? I was first thinking of 50VA, 2x 12V, 2x 2.08A like this one:
RKT 5012: Ringkerntrafo, 50 VA, 2x 12 V, 2x 2,08 A bei reichelt elektronik
But I'm sure there are also transformators with mumetal shielding? Any suggestions on this?
