Active Power Releases New G-Series Line of UPS Units

Active Power has managed to make a name for itself in the field of backup power and infrastructure systems over the past couple of years, and now, the company has decided to add yet another interesting to their lineup, namely the new G-Series line of its high efficiency flywheel based CleanSource UPS (uninterruptible power supply) system.

The G-Series is the latest iteration of Active Power’s current generation of UPS technology that provides a higher value, feature-rich solution for mission critical operations in power applications that range from 300 kVA to 600 kVA.

The G-Series is offered in both 480 volt (300 kVA and 600 kVA) and 400 volt (250 kVA and 500 kVA) power configurations with N+1 capability.

For those of you who're not really familiar with the topic, it's important to mention that flywheel technology is an interesting alternative to chemical batteries.

Flywheel energy storage systems store kinetic energy, energy produced by motion, by constantly spinning a compact rotor in a low-friction environment. When short-term back-up power is required because utility power fluctuates or is lost, the rotor's inertia allows it to continue spinning and the resulting kinetic energy is converted to electricity.

Active Power's CleanSource Flywheel Technology integrates the function of a motor, flywheel rotor and generator into a single integrated system. 

The motor, which uses electric current from the utility grid to provide energy to rotate the flywheel, spins constantly to maintain a ready source of kinetic energy, while the generator then converts the kinetic energy of the flywheel into electricity.

“Designed based on customer feedback, the G-Series is an enhancement to our current generation of UPS technology and is a cost and feature optimized solution for the 300 to 600 kVA power range,” commented Uwe Schrader-Hausmann, chief technical officer and vice president, Engineering at Active Power, not providing, unfortunately, any info regarding the pricing of these advanced UPS solutions.
