Approval Type

Notes

UL

Recognized under the Component Recognition

Program of Underwriters Laboratories, Inc.

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).

VDE

Certified according to DIN EN 60747-5-2

(VDE 0884-10 Part 2): 2003-01,

DIN EN 60950 (VDE 0805): 2001-12; EN 60950: 2000

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).
