RECOM Switching Regulator, 4.5W Power Rating, 96% Maximum Efficiency - R-78AA-0.5 Series - R-78AA9.0-0.5SMD


Has a mismatch between your power supply and the needs of your equipment left you scratching your head? Let this switching regulator from RECOM smooth things out. It converts input voltages between 11 and 32V DC to a 9V DC output, helping keep your supply and devices in sync. As it gets to work in 50ms, the unit slashes warm-up times and ensures your system's ready to go pronto. Automatic short-circuit protection shakes off sudden electrical faults. With narrow body measurements of 15.3 (L) x 9.6 (W) x 8.8mm (D), this a compact choice for crowded panels.

• Low ripple voltages of up to 40mV, so it limits disruption from electrical noise
• Mounts directly to surfaces, making for an easy installation
• Plastic housing with epoxy resin potting for effective insulation
• Wide operating temperature range between -40°C and +71°C, making it suitable for harsh industrial settings

Applications


• Security cameras
• Food production
• Logistics industry

Do I need to install a heatsink to use this product?


No. This regulator delivers conversion efficiencies up to 96% to minimise heat build-up. This means there's no need to make space for a heatsink in your system.
