PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1771-P5 is a PLC-5 power supply module designed for chassis mounting. It converts a nominal 24V DC input into a regulated 5.06V DC backplane output. The unit delivers up to 8A backplane output current with an operational input between 20.5V and 30V DC. Maximum real input power is rated at 57W.
Circuit protection uses an integrated 5A, 32V normal-blow fuse. Isolation between the input line and chassis ground is tested at 1500V AC or 2160V DC for one second. Operating ambient temperature spans 0 to 60 degrees Celsius without derating. Non-operating storage temperature spans -40 to 85 degrees Celsius under 5 to 95 percent noncondensing relative humidity.
