MAN0094/2
Description
This electronic power supply for three phase 208VAC - 50/60Hz input, has been
designed to feed from 2000 to 7000W short arc Xenon lamps, meeting all the
requirements of lamp manufacturers to ensure correct operation, long life to the lamp,
and high reliability.
Thiscompactandlightweightpowersupplyhas beendesignedtomeettherequirements
of a unit to be installed inside a cabinet.
Its particularly compact design, the advanced circuitry and the displacement of input
and output terminal board and the lamp current adjustment make the unit suitable to a
wide variety of applications both in vertical and horizontal position and specifically:
-standard film projection
-theatre applications
-architectural applications
-solar simulations.
