Notes
In accordance with UL 1577, each ADM2490E is proof tested by
applying an insulation test voltage ≥ 6000 V rms for 1 second
(current leakage detection limit = 10 μA).
In accordance with DIN EN 60747-5-2, each ADM2490E is proof
tested by applying an insulation test voltage ≥ 1590 V peak for
1 second (partial discharge detection limit = 5 pC).
