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. The EFS 8481 model is a 20 kVA AC voltage source used to set magneto-thermal breakers on production line. This power supply delivers a sinewave output isolated from the network, at a frequency of 50 or 60 Hz, and is adjustable from 0 to 1300 Arms in 7 ranges. 2.5 A / 200 V 10 A / 120 V 40 A / 30 V 125 A / 30 V 250 A / 30 V 650 A / 30 V 1300 A / 15 V
