The power supply units of the PSU67 series 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 - depending on the type - 2 A, 4 A or 8A. Thanks to their universal AC/DC input, the power supplies can be used worldwide in numerous networks. The high efficiency of up to 90% provides a good energy balance.
