АП1 power adapter

Purpose:

The АП1 supplies БУАВР.х.х.х.Т units from the 0.4 kV busbars of transformer substations during normal, transient and fault conditions.
The АП1 has two equivalent supply inputs plus a common "N" input, which is connected to the common neutral of the ATS panel. The АП1 supply inputs should be connected to phases of different 0.4 kV substation sections. This keeps the БУАВР powered as long as voltage is present on at least one incomer.
Climatic category of the АП1 — У, placement category 3 per ДСТУ ГОСТ 15150.
