What is a flywheel power system?
A flywheel power system is a “mechanical battery” that stores energy kinetically in the form of a rotating mass. This energy is immediately convertible to DC power. Like a lead-acid battery bank, a flywheel power system connects to the DC bus of a UPS, charging from the bus and returning power whenever the bus voltage droops below a programmable threshold. It can supplement or completely eliminate the need for lead-acid batteries in UPS applications by riding-through short duration power quality events and brief outages or until your genset comes on line. When used in conjunction with UPS batteries, a flywheel serves as the first line of defense, isolating the redundant battery bank(s) from all cycling events.
