Validus DC Systems - Product Offering

Product Offering

Validus’ end-to-end solution begins with the Power Quality Module (PQM), which is an air-cooled, mission-critical grade rectification system that converts alternating current (AC) power from the utility to high voltage direct current (-575 V) power.

From the PQM, high-voltage DC power is fed to the Power Distribution Module (PDM-575) which acts as a common interface for all system components in the power infrastructure of the data center. The PDM-575 is a scalable switchboard that simply integrates and controls power distribution from multiple system inputs such as the utility, stored energy devices, photovoltaic systems, distributed generation equipment, wind turbines and batteries and provides the necessary critical load distribution of -575 VDC power to the Power Converter Units (PCU).

The enabling component of Validus’ DC power solution is the revolutionary Power Converter Unit (PCU) 120, which uses patented technology to efficiently convert -575 VDC to safe, usable -54 VDC power, distributing 120 KW of power to the server row. Located at the midpoint of each server row, the PCU-120 consists of four (4) 30 KW integrated, hot-swappable Power Converter Modules, (PCM-030), which are highly efficient power conversion devices that deliver regulated output to power any load demand up to 120 KW per PCU. An optional Power Distribution Module (PDM-055) designed specifically to distribute low voltage DC power short distances mounts adjacent to the PCU-120 and delivers -54 VDC to the point of use (server rack).

Normal or stored energy power in the Validus DC solution can be provided by batteries, photovoltaic devices, wind turbines, fuel cells, fly wheels or any DC source with the proper voltage. Typical modular battery cabinets with a battery charging system can be seamlessly integrated into the PDM-575 offering the equivalent functionality of a UPS system. The standard PBS battery cabinet system supports predefined battery backup run time and utilizes a ten year “maintenance free” battery system in a stand-alone or parallel configuration. Validus’ PQX is an air-cooled, AC powered, stand-alone battery charging system that includes an interactive LCD display for monitoring information and an automatic restart after a high-voltage shutdown event.

Validus’ “Hybrid Power” technology brings together attributes of AC system design and DC energy efficiency to promote scalability, reliability and modularity, as well as an improvement in energy efficiency by up to 40%.
