Uses:
It¡¦s a 2MM thick double-sided holed board with 2-ounce copper foil.
All transistor circuit is applied . That the
remaining noise of power supply is eliminated effectively. The two
stabilized voltage supplies (positive and negative each or two
positive voltage) on the board are completely separated, which can
be used dependently or combined. This board can be applied to CD
players, DACs, preamplifiers and power amplifiers modification
(positive and negative channels or two positive voltages).
We apply this circuits in our single
end 35W class A amp, no any Hum noise from the speakers.
Size
: 100 (L) X 90 (W) X 58 (H) (include the heat sinks)
Price of each production
board:
USD 32.00
(Excluding shipping charge)
Type 1 :
output 5 to 12V .
(Adjustment)
Type 2 :
output 12 to 24V
.(Adjustment)
Type 3 :
output 24 to 50V . (Adjustment)
If the output much more than 800MA , We advice you install a bigger heat sinks , or
install the transistors on the classis )
Note:
1,Don't short the output , it
will burn die the transistors!
2,Input AC voltage must
apply two separate groups
transformers .(If you only own the 3 wires transformers, when you
place order, let us know, we will adjust the circuits can let PSU09
work for your transformers)
3, Input AC voltage high than
output DC voltage had 2 to 5VAC is ok.
4, The standard heat sinks can
offer 3W power heat dissipate , For example, if input is AC 15V, it
change to around DC19V ( around 1.25X times than input AC voltage) ,
if output 14V, have 5V DC voltage different, the safe output current
is I = 3W / 5V =600MA, if the you want more than 600MA output,
replace bigger heat sinks can output up to 1.5A.
