STATIC UPS: They
are: line interactive and true on-line (double conversion). A static UPS
system usually consists of a battery to provide continuous source of
electrical power; a rectifier/charger to maintain battery charge and to
provide input to inverter when utility power is available; an inverter to
provide power to load during normal operation; a static switch to transfer
load automatically and without disturbance between inverter and utility
power; a manual switch to bypass the static switch for maintenance; input
and output isolation transformers and filters to provide appropriate
isolation and disturbance attenuation; and monitors, sensors, and control
circuits

Flywheel Ups: Flywheel
power systems are low speed, stat,
carbon fiber flywheel rotors with an integrated iron-less generator inside a
sealed, housing. They store energy mechanically in the form of kinetic
energy. The use of a flywheel power system can improve the overall
life and reliability of an uninterruptible power supply (UPS) or
conventional lead-acid battery. Flywheel DC energy storage systems
provide a tightly regulated, adjustable DC voltage to replace or augment
batteries in UPS systems. Other types of flywheel power systems
are also available

Three Phase Ups
: Three phase
uninterruptible power supplies (UPS) are devices that operate in
conjunction with existing electrical system to provide power conditioning,
back-up protection and distribution for electronic equipment loads and to
prevent power disturbances (outages, sags, surges, spikes, noise, etc.) from
affecting the performance and life of the electronic device and vital data.

Frequency Converter
: A
frequency converter or frequency Changer is an
electronic device that converts alternating current (AC)
of one frequency to alternating current of another
frequency

Industrial UPS:
A
UPS specifically designed for industrial application s. A
reliable a7 cost efficient UPS designed for industrial
shop floor, automation control rooms and other critical
processes that require high power, with good quality &
performance in an industrial environment. These are three
phase online industrial UPS. The built in maintenance
bypass switch and modular design approach assure low mean
time to repair & reduce service costs compared to
legacy Uninterrupted power sources.
