PSU67 on-machine power supply units are IP67-rated and can be mounted in the field. Short power drops of maximally 50 ms are bypassed independently by the devices. Failsafe operation is enhanced through no-load and short-circuit protection as well as passive air cooling. The output current is 2, 4 or 8 A, depending on the type. Because of their universal ac/dc input, these power supplies can be used worldwide.
