PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1794-PS13 is a FLEX I/O power supply module. It converts an input range of 85 to 264V AC into a 24V DC nominal output. The module provides up to 1.3 A of output current and delivers 31.2 Watts of power. Its operating input frequency spans from 47 to 63 Hz.
This open-type module provides sufficient power surge capability to drive up to four FLEX I/O adapters. It maintains an output voltage regulation range between 20.4 and 27.6V DC. An integrated indicator illuminates green when the output voltage stays between 20.4V DC and 28V DC. The supply shuts down if current exceeds 1.4 A or overvoltage reaches 35V DC.
