The ADVR-54 is a compact size, robust and high reliable voltage regulator. Innovative heat sink significantly increases cooling efficiency. Working on 220/380/440/480 Vac with selectable switches. Capable soft start voltage ramping, over excitation protection and a digital low frequency protection circuit, preventing thermal drift. EMI suppression and automatic shut off output when voltage sensing is lost, with a built-in high capacity fuse.
