Murata Power Solutions IRH-W80 Isolated DC-DC Converters

Murata Power Solutions IRH-W80 Isolated DC-DC Converters have a conformally coated PCB design and are encapsulated for harsh environments. These devices include overvoltage, overcurrent, short-circuit, overtemperature, adjustable undervoltage lockout, remote ON/OFF, current-limit adjustment, and a hold-up input for an external capacitor. The IRH-W80 converter features an operating baseplate temperature range from -40°C to +100°C and an output power of 250W. These converters come with output voltages of 12V, 24V, and 54V and a wide input voltage range from 16V to 160V. Typical applications include railway equipment, transportation systems, industrial equipment, and other applications requiring isolated DC-DC conversion from wide-ranging DC battery supplies.
