Organization
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).
