Presentation

For many years, EFS has been developing multi-range power supplies for testing AC and DC contactors. 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.

Range of voltage sources:

EFS 8371: This 220 VA AC voltage source is used for testing AC contactors in production lines. . It is adjustable from 0 to 700 Veff in 6 ranges to optimize accuracy.

EFS 8373: This 40W DC voltage source is used for testing continuous contactors in production line. It is adjustable from 0 to 600 Vdc in 4 ranges to optimize accuracy.
