The Keyence CA-U5 is a high-performance 24 VDC power supply unit designed to provide stable and efficient power for machine vision and automation systems. Engineered for reliability in industrial environments, it ensures Keyence cameras, controllers, and lighting units receive consistent power, helping manufacturers maintain accuracy and uptime in production processes.

One of the key strengths of the CA-U5 is its wide input voltage range, supporting 85–264 VAC at 47–63 Hz as well as 110–370 VDC. This versatility makes the unit suitable for global deployment, allowing manufacturers to standardise power supplies across facilities with different regional electrical standards. By offering both AC and DC input compatibility, the CA-U5 simplifies system integration and reduces the need for multiple models.

The CA-U5 is also engineered for high efficiency, delivering 82% efficiency at 100 VAC and up to 85% efficiency at 200 VAC under full load. This minimises wasted energy, lowers operating costs, and reduces heat output, contributing to system stability and longer equipment life. For production environments running 24/7, this efficiency is critical to maintaining sustainable and cost-effective operations.

In terms of input performance, the unit operates at a rated input current of 3.9 A max. (100 VAC) and 1.8 A max. (200 VAC), ensuring smooth handling of varying load conditions. On the output side, it delivers a rated voltage of 24 VDC, providing the stable and regulated power required for sensitive vision systems. By maintaining constant output, the CA-U5 prevents voltage fluctuations that could disrupt inspections or damage equipment.

Weighing approximately 1540 g (3.40 lb), the CA-U5 combines durability with a compact design that fits easily into control panels or machinery setups. Its rugged construction ensures consistent operation under vibration, long duty cycles, and other challenging industrial conditions. This reliability reduces downtime and maintenance, making it a cost-effective choice for high-throughput production lines.

The CA-U5 also complies with key international standards for electromagnetic compatibility (EMC), ensuring it integrates smoothly into multi-device systems without interference. When paired with Keyence vision solutions, the CA-U5 supports accurate, repeatable inspections by guaranteeing stable power delivery at all times.

Applications for the CA-U5 span industries such as automotive, electronics, packaging, and pharmaceuticals, where precision machine vision and automation are central to quality control. Its combination of stability, efficiency, and durability ensures that production lines remain reliable and efficient.

In summary, the Keyence CA-U5 is a robust and efficient 24 VDC power supply designed for global industrial use. With its wide input range, high efficiency, stable output, and rugged construction, it provides the dependable performance required to power vision systems and automation equipment. For manufacturers seeking a reliable power solution to maintain consistent inspection and production quality, the CA-U5 is a proven choice.
