My desire to earn more salary made me land in Middle East leaving back my job in R & D of a manufacturing company in India where I worked for 2 years.The job I got here is in the Sales field which was very new for me but I took a chance......Being in Sales one deserves to be more aggressive and...
Hi All,
its understood that HId lamps operate at 110V while its running, eventhough the i/p supply voltage is 230V...........the remaining voltage being dropped across the ballast.
Now what confuses , is the current drawn by the lamp and the input current.
for example.. if the lamp...
Why is that supply voltages have been standardised to 230/240/250V...ALso in America we find it is different in different regions, 120/240/277...what are the advantages of this?Also does the frequency play role in our household equipments like tv,refrigerator...
I need some help regarding the design of CWA ballasts.
There are different tappings on the primary of the ballasts e.g.120 V,230 V,277 V etc.
On the secondary the HPS lamp is connected via a capacitor.
B'cos of current limiting an insulation fault in the secondary coil results in a slow build...
I have a circuit which is used to control a 12 V dc ,3W ,stepper motor using PIC.The input supply is 120 V ac,60 Hz which is then reduced to 12 V using capacitor as impedance.
The electrolytic capacitor used after the bridge is 470 mfd,25 V.
Now I have decided to run the motor by taking 12 V...
