Lovato’s DCTLA4801200 is a thyristor module delivering 120 kvar at 480VAC for high‑capacity AC applications. It features current control and a rated operating voltage of 400...480VAC, supporting robust performance in demanding environments. With Ui 480 V and Uimp 4 kV, it is engineered for insulation integrity and surge withstand, helping maintain reliable operation in industrial control assemblies.
Built to IEC/EN 60947-4-3 and meeting EMC standards IEC/EN 61000-6-2 and 61000-6-4, this module integrates cleanly into compliant panels. A NO AC1 contact and AC1 3A contact rating simplify auxiliary interfacing. With a -30 to +80 °C storage temperature and 6680 g construction, it supports dependable logistics and sturdy cabinet mounting.
