The DPU was one of the first multi-function distribution relays and many of them are still in the field. A rebuild of these can be much more cost effective than a replacement, which usually involves a lot of panel work and an extended outage. Also known as 445V1950-601 as well as other item numbers.
All DPU devices receive a 48 hour burn in and are accompanied by a test report. If you furnish your settings file we will program and test to those settings, otherwise we will test to factory default settings.
