"The IC693PWR325 is a GE Fanuc 90-30 series input power supply unit weighing 2 pounds. The power supply is designed for nominal voltage inputs of 24 VDC or 48 VDC at a power rating of 30 Watts. The power supply can accept an input voltage range from 18 VDC to 56 VDC. Although it can maintain all outputs within specifications with input voltages as low as 18 VDC, it will not start with initial input voltages of less than 21 VDC.
The power supply delivers an output voltage of +5 VDC & +24 VDC relay power output that powers the circuits on Alspa C80–35 Output Relay modules and isolated 24 VDC output. The isolated 24 VDC can be used to power some input modules. Furthermore, the power supply records an inrush current of 4A peak, 100 ms maximum. It has an overvoltage of 5 VDC output: 6.4 to 7 V and an overcurrent of 5 VDC output: 4 A maximum."
