Lovato’s DCTLA4800090 is a DCTL thyristor module engineered for dependable AC control. Delivering 9kvar at 480VAC and a rated operating voltage of 400…480VAC, it integrates current control to manage load conditions. The module includes an NO contact with AC1 characteristics and a 3 A rating for signalling. Ideal for panel builders and OEMs, it offers a compact, robust option for AC systems operating within these voltages.
Built to IEC/EN 60947‑4‑3 and EMC standards IEC/EN 61000‑6‑2 and 61000‑6‑4, the unit provides a rated insulation voltage Ui of 480 V and an impulse withstand Uimp of 4 kV. With a storage temperature range of −30 to +80 °C and a 1740 g build, this Sustainability‑certified component suits demanding industrial environments requiring compliant, reliable thyristor‑based control.
