Description
Field of application
Applications that need a continuous variation of alternating current, single-phase or three-phase, from zero to the maximun, with high resolution and a constant degree of intensity.
Description and production series
Autotransformer for voltage variation wound on toroidal core with graphite rollers.
Single-phase standard versions: 127 V from 160 to 7000 VA, 230 V from 160 to 11000 VA and 400 V from 500 to 10000 VA, manual or power-assisted control. For higher powers variators are connected in parallel.
Three-phase standard versions: 3*230 V from 480 to 21000 VA and 3*400 V from 480 to 33000 VA, STAR connection, manual or power-assisted control. For higher powers variators are connected in parallel.
