ARLINGTON HIEIGHTS, ILLINOIS, USA, October 23, 2009: Hill Tech Sales, a leader in components for UV curing today introduced an article on how to calculate input current required by a UV lamp ballast
How do you calculate input current required by the ballast?
Input current to ballast = [(NOMINAL WATTS / Power Factor) * (Power supply efficiency)] / Ballast input voltage
Example:
For:
NOMINAL WATTS = 10,000
Power Factor = 0.92
Power supply efficiency) = 90%
Ballast input voltage = 220VAC
Gives:
Input current to ballast = [( 10,000 / 0.92) * ( 0.90)] / 220 = 44.47 Amps
