3 XTNSIV TSTING FACILITIS IN-HOUS PowerTech has years of experience in testing with high power applications. Before delivery to the customer, each converter is tested with the original motor only a fully tested package of power converter and motor is delivered to our customer. New motor types are identified with special load tests. That ensures a high accurate control of the torques and in the end, best quality.
