TRC Electronics offers a wide selection of 3.3 Vdc encapsulated AC/DC power supplies. These 3.3 volt power supplies are potted and packaged in an encapsulated case that provides an additional level of physical protection to the power supply’s components. Additionally, the case advances the protection in environments that experience dust or vibration. These 3.3V encapsulated power supplies are available in PCB mount or chassis mount. The PCB mount eliminates the need for 3.3 volt output cables in your system and provides convenient 3.3V power on the circuit board. The chassis mount is suitable when mounting directly to a dedicated circuit board is not practical. The leading manufacturing partners of 3.3 Vdc encapsulated power supplies include MEAN WELL and TRACO Power. 3.3 volt encapsulated power supply models are available to meet UL 60950 for ITE applications and IEC 60601-1 3rd ed. for medical applications. Many medical grade models are 2xMOPP rated and are suitable for BF, body float applications. The 1W and 2W encapsulated MEAN WELL solutions offered operate off of 277Vac input voltage to power the expanding lighting, smart building and sensing applications in North America.
