The 1794-PS1 Flex I/O Power Supply Module by Allen-Bradley is an AC power supply module which supplies 24V DC power to any 3 adapter modules connected to it. It has 120V AC and 230V AC nominal voltage supply at 47-63Hz and it has a range of 85-265V AC. The 1794-PS1 has an inrush current of 30A for a single AC cycle with a nominal input current of 0.7A and 0.2A which remain uninterrupted even when the input power drops out for a half cycle at 47Hz and 85V AC. The 1794-PS1 has a nominal output of +24V DC with an output voltage range of 22.8-25.2V DC and a maximum output current of 1A. The minimum load on the output is 100mA and it has an output surge of 23A for 2ms completely sufficient to drive all 3 Adapters. The 1794-PS1 provides over-voltage protection by internally limiting the output voltage to 35V DC and providing voltage isolation at 1500V AC for 1 minute and 2500V DC for 1 second. The module is mounted vertically or horizontally using a DIN rail or panel mount and it has total dimensions of 3.4in x 2.7in x 2.7in. It has a 0-55 0C (32-131 0F) functional temperature range at 5-95% relative humidity and it is IEC-tested and rated to maintain function within a specified standard at an operational vibration of 5G and a shock rating of 30G. The 1794-PS1 uses a 4mm2 stranded wire size and 3/64 inch (1.2mm) maximum insulation.
