You might say that Tech/Ops Sevcon prevents electric vehicles from becoming speed demons. The company makes Sevcon solid-state controllers, which regulate motor speed and acceleration in battery-powered vehicles, such as forklifts and coal mining equipment. Through a UK-based subsidiary, Tech/Ops Sevcon also makes metalized film capacitors for power electronics, signaling, and audio equipment applications. Targeting manufacturers of aerial lifts, forklift trucks, and underground mining vehicles, Tech/Ops sells directly and through a network of independent dealers in Asia, Europe, and the US. About 60% of sales are to customers outside the US.
