Bel Fuse / Power-One HBB5-3/OVP-A Power Supply

The Bel Fuse/Power-One HBB5-3/OVP-A is a 15 W open-frame power supply delivering regulated 5 VDC at 3 A from universal 100-240 VAC, 50/60 Hz input. Integrated overvoltage protection (OVP) safeguards downstream electronics against voltage surges, while overcurrent, short-circuit, and thermal shutdown protection ensure reliable operation across industrial and embedded applications.
