CSU2400AP-3-111 is a 2400W AC-DC front-end bulk power supply designed for compute, storage, and networking equipment in the common redundant power supply (CRPS) form factor. The unit operates from 180–264 VAC input with a maximum input current of 13.8A at 200 VAC, delivering 2400W of output power with 94.0% peak efficiency (Platinum rating). It features a main DC output of 12.2V at 196.7A nominal and a standby output of 12.0V at 3.5A, with output regulation maintained within ±5% and output ripple limited to 1%. The power supply is housed in an industry-standard 1U × 73.5 mm × 185 mm form factor with reverse airflow configuration, achieving class-leading power density of 75 W/in³. Operating temperature range is -5 to 50°C at full rated power with allowance up to 65°C at 60% load for short-term operation. The unit includes PMBus power management interface, meets IEC 60950/62368 safety standards, and carries multiple certifications (UL/cUL, CE, CB, KC, EAC, BIS, CQC, BSMI). This configuration is ideal for high-density data center and enterprise applications requiring flexible, redundant power distribution with minimal footprint.
