UPS means uninterupted supply for computer and electronic
devices.In the UPs one filter is use which mentained the
supply constantaly.There is Two types of UPs On line ups
and OFF line UPs.
UPS means uninterrupted power supply . It is used for
electronic instruments where continuous supply is
required . In UPS one battery bank is there which is used
for storage of power . When external supply is on the bank
get charged automatically . If supply goes off , this
stored DC voltage converted into AC voltage by a inbuilt
inverter . This o/p is fed to load . So a UPS consists of a
battery bank , a inverter circuit and associated
circuitry . There are various types of inverter like on
line , off line , line interuptive etc .
Hi Dears
UPS is for the purpose to give un-interruptible power
supply. This stores the energy in the form of DC by the
controlled rectifier (AC - DC converter) and discharge the
energy in the form of controlled AC by inverter (DC - AC
converter) so as to provide continuous power supply. Here
the back up is derived based on the requirement.
types:
1. Online Double convertion UPS (Normal High capacity UPS)
2. Online Delta convertion UPS (New technology offline
using buck boost Transformers)
3. Offline UPS (economical UPS medium capacity UPS 3 -
30KVA also available in higher capacity)
4. Line Interactive UPS (lower capacity UPS 300VA - max5KVA
output will be Squasi Sinewave).
UPS are used in home, medical, IT and industrial where the
critical load is used.
dear sir,
I have a 2.5kva uniline ups,which works on 148 dc
source, but at present i donot have dc power source, now on
connecting it on ac source it gives indication of presence
of line but on pressing start button nothing happens. is it
possible to switched on the same ups without connecting the
dc source.
Ups means uninterupted power supply. In UPS one battery
bank is there which is used for storage of power . When
external supply is on the bank get charged automatically .
If supply goes off , this stored DC voltage converted into
AC voltage by a inverter .a UPS consists of a
battery bank ,
The main building blocks of any given UPS (on-line, off-line
or stand-by) are the charger, inverter, static switch or
static disconnect and battery. The charger converts AC to DC
power which float charge is the battery and feeds
the inverter. The inverter converts DC to AC power, and the
static switch or static disconnect is a solid-state device
used to apply or disconnect AC power. The battery stores DC
power that is used as a back-up power source when
the utility power is not available.
UPS is an electronic device which functions as alternative
power source which supply power continuosly to the senstive
electronic devices under circumstances
Hello, im taking an introduction to PLC..and i'm having a
hard time on creating a program for 2 lamps blinking
alternately with this button characteristics:
1.) One push button (starts upon pressing)
2.) Same push button (when pressed again, will pause the
system)
3.) Same push button (when pressed again, will continue the
paused system)
4.) Same push button (when pressed within 2 seconds, will
shut off the system)
Pls..i know this is just a simple problem for you guys..
is any body explain me why return current in three phase
power system is less then in a red, yellow, blue phases???
as we know Ir+Iy+Ib=In then why nutral wire has less then
phase current????
What happens when generator is running with leading power factor on it say -0.96. what are the effects of it on alternator and the other generators operating in parallel to it.
