Information About 1768-PA3
The 1768-PA3 is part of the CompactLogix family and serves as the primary power source for 1768-system modules. Built with an AC/DC input design, the module accommodates both global AC mains and DC industrial power systems, simplifying integration across diverse applications. Its rugged architecture includes a factory-installed non-replaceable fuse for internal overcurrent protection, enhancing safety and reducing maintenance requirements. Designed to deliver 1.4 A at 24V of backplane current, the module reliably powers CPUs, communication adapters, and expansion modules within CompactLogix control architectures. With an open-style enclosure, it is intended for installation inside an approved industrial control panel and meets typical efficiency and inrush performance demands expected in automation environments.
Key Features:
- Wide AC/DC Input Range: Accepts 85–265VAC or 108–132VDC for flexible installation.
- Backplane Power Delivery: Supplies 1.4 A at 24V to CompactLogix modules.
- Integrated Overcurrent Protection: Includes a built-in, non-replaceable fuse for added safety.
- High Inrush Capacity: Supports 25–50A nominal inrush depending on voltage range.
- Compact, Panel-Mount Design: Open-style housing for use inside industrial enclosures.
- High Efficiency: Operates at approximately 75% typical efficiency.
- Robust Industrial Performance: Designed for reliable operation under varied industrial conditions.
- AC Power or DC Power Options: Ideal for mixed-voltage installations and retrofit environments.
The 1768-PA3 delivers the reliability and precision required for dependable power distribution in CompactLogix automation systems.
