Main Features and Advantages
High-Efficiency Power Conversion: The Allen-Bradley 1606-XL480EPT achieves typical efficiency of 90.5% at full load, significantly reducing energy waste and heat generation within the control cabinet . This high efficiency translates to lower operating costs and allows for denser panel layouts without compromising thermal performance.
Active Power Factor Correction: The integrated active PFC circuit brings the input current waveform into phase with the voltage, achieving a power factor greater than 0.95 . This reduces harmonic distortion fed back into the AC line, meeting stringent power quality standards and enabling the use of smaller upstream breakers and wiring .
PowerBoost Overload Capability: The Allen-Bradley 1606-XL480EPT delivers up to 25 A at 24 V DC for short durations (less than 30 seconds), providing the reserve capacity needed to start high-inrush loads such as motor starters, valve actuators, or capacitive loads without nuisance tripping or voltage sag .
Wide-Range Auto-Selecting Input: The power supply automatically adapts to either 100-120 V or 200-240 V AC input without manual switching, simplifying global deployment and reducing the risk of incorrect voltage configuration . The continuous operating range extends from 85-132 V and 184-264 V AC, providing tolerance for line voltage fluctuations.
Robust Environmental Tolerance: Operating reliably from 0°C to +70°C (with derating above 60°C), the Allen-Bradley 1606-XL480EPT withstands the temperature variations typical of industrial control rooms and production floors . The fanless convection-cooled design eliminates dust ingress concerns and moving-part wear.
Comprehensive Protection and Diagnostics: The Allen-Bradley 1606-XL480EPT incorporates electronic overload protection with automatic recovery, overvoltage lockout, short circuit protection, and overtemperature shutdown. A green LED provides visual confirmation of normal output voltage status, enabling quick troubleshooting .
