        "Developed from the JBK5 machine-tool control transformer. Uses low-loss silicon-steel laminations, flame-retardant bobbins and terminals, Class H oxygen-free copper wire, Class H insulation varnish and insulation materials. CNC argon-arc welding joins the laminations and base into a single assembly, followed by overall vacuum-pressure varnish impregnation.",
        "The brochure highlights compact construction, a neat appearance, low ripple, low power consumption, high control capacity and a high protection level. Mounting dimensions are described as equivalent to JBK5."
