New Tech News – High Power Density 3-phase UPS

9900D Series UPS from Mitsubishi Electric are Ideal for Cloud and Colocation Data Centers.

Mitsubishi Electric 9900D UPS

Earlier this year, Mitsubishi Electric announced the release of the 9900D, a line of UPS products designed for the relentless demands faced by today’s cloud and colocation data centers.

The 9900D is the smallest modular scalable static UPS yet is capable of high power densities. The 9900D uses 400kVA power modules integrated with intelligent bypass modules. The bypass modules are available in 1200kVA, 1600kVA, 2000kVA sizes with up to five power modules. The scalable design adds supplemental modules over time to meet increasing capacity needs, making hyper-scale expansion fast, easy and economical.

All the modules in the 9900D UPS line are lightweight and have small footprints. With the latest 7th generation IGBT based 3-level topology, the 9900D operates at up to 97 percent efficiency.  The advanced control architecture results in increased component life, low harmonics and rapid responses to transients. Internal component selection and intelligent cooling design increase reliability and a 15-year capacitor life, reducing maintenance costs and lowering the total cost of ownership.


The 9900D Series UPS features N+1 redundancy constructed of modular power electronics in parallel. If one of these modules were to fail, the 9900D internal controls would isolate the module while continuing to provide critical power protection.


Expandability is a key feature of the 9900D Series UPS. Its modular design enables supplemental modules to be added over time as warranted by increasing capacity needs, making hyperscale expansion faster, easier and more economical.

Small Footprint

The 9900D Series UPS creates more white space. It can handle the same load in as little as two-thirds of the footprint, leaving the remaining third be allocated to revenue generating equipment.
