LHY Audio Linear Power supply module
Low noise 2SA1943 3.3-15V DC
This LHY Audio low noise linear power supply module offers a very good price/performance ratio. It integrates a D15XB high power diode bridge, a LM317T and TL431 voltage regulator as voltage reference and a Toshiba 2SA1943 high current PNP transistor for its output. This ensures excellent linearity and stability. The module provides a basic output voltage of 12VDC and can be adjusted over a range of 3.3V to 15V DC.
| Input voltage | Output voltage |
|---|---|
| 9VAC | 5VDC |
| 12VAC | 9VDC |
| 15VAC | 12VDC |
| 18VAC | 15VDC |
It is strongly recommended that the module be associated with a heat sink, especially from a load current of 1A.
