Premium Model UDB –A
The Premium model UDB-A has a 60-amp, 208-volt, 3-phase inlet with a 60-amp, 208-volt, 3-phase outlet. The three-phase power is broken into three 120-volt circuits within the box. There are three 120-volt, 20-amp GFCI duplex receptacles circuit-breaker protected at 20 amps. This UDB incorporates amp meters on the mains (0 to 75 amps) to allow the user to ensure that single-phase loads are equally balanced across the three phases from the power supply. This unit is used in applications that require feed-thru power to supply larger areas. A circular receptacle is provided for use with an Base-X shelter wiring harness.
