IRH-54/4.7-W80PB-C

IRH-54/4.7-W80PB-C is a 250W IRH-W80 series ultra-wide input encapsulated half-brick isolated DC-DC converter. The industry standard half-brick package offers high-efficiency levels. The fully isolated DC-DC module accepts a wide input voltage range while maintaining a fully regulated single output. The output voltage features overvoltage, overcurrent, short circuit, and over-temperature protection. Other features include adjustable under-voltage lockout protection, adjustable current limit threshold, positive or negative logic enable, and a Hold-Up pin to allow connection of an external capacitor. Certified to UL-60950-1, CAN/CSA C22.2 60950-1, 2nd edition.
