3U Rack-Mounted DC Power System for Compact Medium and High Power Systems
Compact, efficient, and reliable, the ACE306 is a rack-mounted DC power system designed to power traffic and industrial systems where performance is non-negotiable. Compatible with the CAR30100TP-A rectifier, available in 110V, 84V and 96Vdc output options, it delivers high power density in a compact 3U footprint — making it one of the more capable PSU shelves in the Alpha Innovations power shelf range.
Featuring the MCU30110M6, an integrated COMPAS-based monitoring unit, the ACE306 provides remote supervision and control, helping reduce operational costs through real-time data analysis, energy optimization, and automated testing. For advanced customization, create your own alarms or select pre-assembled, pre-programmed, and tested configurations ready for immediate deployment. Custom logic can be implemented locally with Python scripting directly on the monitoring unit, without relying on the cloud. Inview MESH consolidates data from all deployed monitoring units into a single interface, providing unified monitoring and reporting, with an API for seamless integration into existing systems and applications.
Built for indoor and outdoor environments, the ACE306 combines smart protection and adaptability — including intelligent power de-rating, thermal and voltage safeguards, and module monitoring. Designed for parallel operation, it features active PFC, IEC/CE compliance, and single-wire load sharing for perfect current balance. An integrated redundancy diode enables hot-swap, fault-tolerant operation, ensuring continuous uptime.
