Lovato’s DCTLA4000075 is a DCTL thyristor module engineered for capacitor switching in power factor correction at 400VAC. Rated 7.5kvar with current control, it supports stable operation across demanding industrial networks. With Ui 480 V and Uimp 4 kV, this compact unit integrates cleanly into control panels, helping engineers implement dependable, low‑maintenance compensation stages.
Conforming to IEC/EN 60947-4-3, 61000-6-2 and 61000-6-4, the DCTL series offers defined EMC performance and insulation thresholds. Auxiliary contact ratings include NO contact: AC1 and contact: AC1 3A, aiding straightforward signalling. With a storage temperature range of -30 to +80 °C and a 1740 g build, the unit suits panel builders seeking ready-to-integrate 400VAC stages.
