RECOM Switching Power Supply, 70% Efficiency, PCB Mounting - RAC04-GB Series - RAC04-3.3SGB
This small but mighty switching power supply from RECOM converts high input voltages to a steady lower output. Put in 305V AC or 430V DC and you'll get 3.3V DC out. This is just what you need to power smaller items like personal computers or handheld electronics. You'll enjoy peace of mind when using your equipment thanks as the module comes with over-voltage and over-current protection, which helps prevent surges from damaging your circuits.
• Extensive operating temperature range between -40°C and +85° to keep your equipment powered even in demanding conditions
• Light 20g weight doesn't place excess strain on circuit boards
• Low-profile size of 37 (L) x 24 (W) x 15mm (H) for easy handling during installation
• 0.05mm pins fit like a glove into through-holes on a PCB
• Encapsulated package for low levels of heat dissipation
