Information About CA-U4

The CA-U4 is part of Keyence’s CA Series power supplies, engineered to provide efficient and reliable DC power in compact form factors. It supports a wide input voltage range from 85 to 264 VAC (47–63 Hz) and delivers a 24 VDC, 6.5 A output suitable for a variety of Keyence controllers and peripheral devices. Built with overvoltage protection and automatic recovery, the CA-U4 maintains safe operation during power fluctuations. Designed for DIN rail mounting, it offers a durable solution for control cabinets requiring space-saving, energy-efficient, and safety-certified power sources.

Key Features:

  • Wide Input Range: Accepts 85–264 VAC or 110–370 VDC input for global power compatibility.
  • High Efficiency: Delivers up to 85% efficiency at 200 VAC under full load for reduced energy consumption.
  • Stable 24 VDC Output: Provides a constant 24 VDC, 6.5 A output suitable for industrial electronics.
  • Overvoltage Protection: Automatic current drop and recovery ensures safe operation during surges.
  • Compact Form Factor: Ultra-compact switch-mode design for tight installation spaces.
  • DIN Rail Mounting: Enables fast, secure installation in control panels and enclosures.
  • Industrial Durability: Operates reliably from -10 °C to +55 °C in harsh environments.
  • Global Safety Compliance: Certified under UL, CSA, EN, and IEC safety standards.
  • Harmonic Current Limiting: Meets EN61000-3-2 for improved electromagnetic compatibility.
  • Low Maintenance: Automatic restart function after voltage interruption for reduced downtime.

The CA-U4 delivers the reliability and performance required for powering automation controllers, sensors, and vision systems in industrial environments.
