The IRQ-W80 and IRH-W80 series of DC/DC converters are designed for embedded applications in the railway, transportation, and industrial sectors. These converters feature a 10:1 wide input range of 16 V to 160 V_DC. This allows a single part number to be used across a wide range of input voltages. The 150 W IRQ-W80 quarter-brick and 250 W IRH-W80 half-brick are available in single output voltages of 12 V, 24 V, and 54 V. The 54 V model is PoE compliant. Features include remote enable on/off, a wide output voltage adjustment range of ±10%, remote sense, hold-up function, pulse out feature, positive or negative enable, and overcurrent protection adjustment. The modules also feature self-protection to external short circuits, overcurrent protection, and overtemperature protection with a self-resetting ability. They also comply with the requirements of EN50155 for shock, vibration, extreme temperatures, and humidity.
