2U Redundant / IS-550R2UPD8UC
550W 2U CRPS High Efficiency Redundant Power Supply
A 550W 2U CRPS 1+1 redundant PSU with dual AC, PMBus, and hot-swap modules — the lower-wattage CRPS option when the chassis is 2U, not PS2 Mini or 1U side-by-side.
Product Overview
What the IS-550R2UPD8UC is built for.
The Xeal IS-550R2UPD8UC is a 2U CRPS redundant supply: 550W 1+1, dual AC, hot-swap modules, load sharing, automatic fan thermal control, and PMBus. +12V is 46A (550W total; +3.3V/+5V combined ≤ 150W). The 75.9 × 83.8 × 229.9 mm CRPS body (specsheet 230 × 76 × 84 mm, 1800 g) is the form-factor split from IX-700 (1U 106 mm) and from IS-600/800 (PS2 Mini). Efficiency 85% typical at 100% load; hold-up ≥12ms at 115Vac / 70% load; peak 660W ≤12ms. DC output connector is specified as ATX.
