Lovato DCTLA4000500 thyristor module delivers 50kvar at 400VAC with dependable current control for demanding AC applications. Part of the DCTL range, this module is engineered for reliable operation at a rated operating voltage of 400VAC. With a rated insulation voltage of 480 V and 4 kV impulse withstand, it provides strong electrical resilience, helping engineers specify a robust, manufacturer-backed solution for reactive power stages and controlled switching requirements.
Built to IEC/EN 60947-4-3 and EMC standards IEC/EN 61000-6-2/-6-4, the DCTL module suits industrial panels and distribution assemblies. AC1 contact details (NO contact AC1; contact AC1 3A) support appropriate interfacing. A wide storage temperature of -30 to +80 °C and 2840 g build reflect practical durability and handling during install and service across UK sites.
