SoundCraft CPS275 - Manual (Page 20)

The +5V Supply.
Max current rating 1.0 Amps. This supply is primarily intended for powering console
internal computers; it also powers the cooling fan.
The AC input is fused by F4 and fullwave rectified by D9-12, with C36 as the reservoir
capacitor. The LM340 regulator has a fixed 5.0V output. C35 ensures regulator
stability.
A protection diode is included; D14 protects the regulator from reverse voltage if there
is a charged capacitor across the output but the voltage on C36 has collapsed.
Diode D23 on the output (CPS275 only) allows supplies to be paralleled for
redundancy.
