SNP-B309
280 Watt
- 280 W continuous fanless power
- Operating temperature up to +70 °C
- Overtemperature protection
The SNP-B309 power supply is characterized by a high efficiency of >85%. Therefore a fanless and very quiet operation is possible. The consistent use of high-quality components, as well as over temperature-, overload-, short circuit- and over voltage protection complete the excellent performance profile of the SNP‑B309.
