Note:
1) Max 380V raw DC input
2) If Input DC = 380V,R3 = 82K or 94K 5W
3) D1,D2,D3 = Green LED
4) D4 Red LED (optional)
5) D5,D6,D7,D8 (optional)
6) If Input DC = 380V, Q2 = MPSA94
7) Q4 = 2SK170BL
8) Q1 & Q3 must be mounted on heatsink or aluminium chasis
9) Adjust R1 for CCS current
10) CCS current > 2 times load current, better sound = 3 times
11) Practicle case:
CCS current = 60ma R1 = 31 ohms Load current <= 30 ma V out = DC 300V
12) Max. input - output <= DC 150V
13) Max. output <= DC 320V |
