The Series 90-30 DC input High Capacity power supply (IC693PWR331) is a 30 watt wide range supply designed for 24 VDC nominal inputs. For applications requiring greater +5V current capacity than is available with the standard supply, this supply allows all 30 watts to be consumed from the +5 V output. It will accept an input voltage range from 12 VDC to 30 VDC. Although it is capable of maintaining all outputs within specifications with input voltages as low as 12 VDC, it will not start with initial input voltages of less than 18 VDC.
