60KVA UPS

3kva Uninterruptible Power Source, For large power units, Dynamic Uninterruptible Power Supplies (DUPS) are sometimes used. A synchronous motor/alternator is connected on the mains via a choke. Energy is stored in a flywheel. When the mains power fails, an eddy-current regulation maintains the power on the load as long as the flywheel's energy is not exhausted. DUPS are sometimes combined or integrated with a diesel generator that is turned on after a brief delay, forming a diesel rotary uninterruptible power supply (DRUPS).

he three general categories of modern UPS systems are on-line, line-interactive and standby. An on-line UPS uses a "double conversion" method of accepting AC input, rectifying to DC for passing through the rechargeable battery (or battery strings), then inverting back to 120 V/230 V AC for powering the protected equipment. A line-interactive UPS maintains the inverter in line and redirects the battery's DC current path from the normal charging mode to supplying current when power is lost. In a standby ("off-line") system the load is powered directly by the input power and the backup power circuitry is only invoked when the utility power fails. Most UPS below 1 kVA are of the line-interactive or standby variety which are usually less expensive.

ETONE UPS can also offer multi-mode operation, whereby a more efficient VFD mode is used unless power conditions warrant that a more highly protective VFI mode is needed. Finally, modular UPS, which use changeable small modules (10 to 50 kVA) to adjust for growth as needed, reduce maintenance, and increase efficiency. UPS are more efficient at higher capacity.
