Products
AC Load Power Smoother (AC LPS)
Maintains AC-grid stability by instantly sourcing or sinking transient power, buffering rapid chip-load fluctuations and stabilizing the current profile at the grid interface. That lets AI data centers support dynamic workloads while reducing the need for immediate electrical-capacity expansion.
- Compact rack design supports 415 VAC or 480 VAC three-phase systems
- 98.2% peak system efficiency
- Modular, hot-swappable PSUs and supercapacitor units
- Comprehensive protection
AC Power Supply Unit (AC PSU) Shelf
Converts three-phase 415 VAC or 480 VAC into regulated 50 VDC with galvanic isolation, for AI and HPC racks.
- 50 VDC output
- Air- or liquid-cooled thermal options: >98.3% peak efficiency
- Power density of 74.46 W/in³
- Cap built-in design for 20 ms hold-up time at 100% load
