Own Products

Apart from customer-specific solutions, MTSA Technopower also markets its own line of products for high power labs. Our product line encompasses equipment for short-circuit testing.


Following the acquisition of KEMA Techniek in 2003, MTSA Technopower became a supplier of equipment that enables controlled high voltage or current injection. This involves equipment for both the direct and the synthetic test circuit.
