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.
The EFS 8545 model is a 3 kVA AC voltage source used to set 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 400 Arms in 5 ranges.
