Ideal for workshops servicing Range Rover, Discovery, Defender, Evoque, Velar and Jaguar MHEV vehicles, it eliminates the need to refit DCDC modules onto cars for functional testing.\u003c\/h3\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eThe JLR 48V DCDC serves as the critical power bridge between 12V and 48V systems. Featuring a built‑in 48V simulated power supply, the tester runs on standard 220V AC mains with no additional batteries or auxiliary power required. It fully supports mainstream DCDC part numbers including L8B2, K8D2, N8B2 and the latest R8E2 series.\u003c\/h3\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0072\/5424\/5449\/files\/item_description_05b88e20-4197-44a7-b336-f258bbb5bd63.webp?v=1771056597\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cdiv\u003e\n\u003ch3\u003eWhy Choose Our JLR 48V DCDC Test Bench?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003eJaguar Land Rover’s 48V DCDC failure is a widespread factory defect across all mild hybrid models.
