For many years, EFS has been developing multi-range power supplies for testing thermal and magneto-thermal circuit breakers.Dedicated to industrial use, these power supplies have many advantages such as the realization of complete test cycles, the possibility of control by PLC. User protection by numerous safeguards is also ensured: isolation, emergency stops, etc.These power supplies are available in laboratory or production version.
