Electrical Compatibility and Input Requirements
Global Input Voltage and Frequency Support
Excalibur PSO models support wide range AC input from 90 V to 264 V, with automatic adjustment for 50 Hz and 60 Hz grids. This ensures reliable operation across regions without manual switch settings.
Power Factor and Harmonic Compliance
High power factor above 0.95 and adherence to harmonic standards reduce load on upstream infrastructure. The design supports dense deployments in data centers where harmonic distortion control is critical.
Performance, Efficiency, and Thermal Design
Efficiency Curves and Load Scenarios
Efficiency exceeds 88% across typical server loads, peaking near 92% at mid to high utilization. Less energy wasted as heat lowers cooling demand and long term operating costs.
Transient Response and Ripple Noise
Fast transient response maintains regulated output during sudden current spikes. Low ripple noise safeguards sensitive communication and measurement circuits in industrial setups.
Physical Installation, Form Factor, and Integration
Chassis Mounting and Airflow Management
Screw mount patterns and support brackets enable secure installation in 19-inch racks or standalone enclosures. Proper airflow routing maintains safe operating temperatures and extends MTBF.
Cable Management and Connector Types
Modular cable harness options reduce clutter and improve serviceability. Standardized connectors minimize installation errors and simplify future upgrades or replacements.
Key Evaluation and Deployment Recommendations
- Verify input voltage and frequency range matches your site grid specifications.
