hi all, i have some 600VA low-voltage dimmers being used with a 120VAC/24VAC magnetic transformer. this transformer is rated for 450 Watts. a unique feature of the transformer is a boost tap which adds in 0.5V increments to the output AC; i.e. if the output was 23VAC - which could cause problems for the 24VAC lights - then the transformer could be setup for two boosts.
the loads are 24V cove lights which have drawn as much as 350 Watts from the transformer.
back on the primary side, it is the dimmers that have been failing. the measured amps from the dimmers is only around 3 Watts.
1) could the 350 Watts on the secondary side of the transformer equate into more than 600VA for the dimmer on the primary?2) could in-rush current be a problem with a setup like this?
3) could the boost-tap be causing extra impedence on the primary?thanks for any help you can provide!
