5 / 16 page ADM2490E Rev. A | Page 5 of 16 REGULATORY INFORMATION Table 5. ADM2490E Approvals 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). INSULATION AND SAFETY-RELATED SPECIFICATIONS Table 6. Parameter Symbol Value Unit Conditions Rated Dielectric Insulation Voltage 5000 V rms 1 minute duration Minimum External Air Gap (Clearance) L(I01) 7.45 mm min Measured from input terminals to output terminals, shortest distance through air Minimum External Tracking (Creepage) L(I02) 8.1 mm min Measured from input terminals to output terminals, shortest distance along body Minimum Internal Gap (Internal Clearance) 0.017 mm min Insulation distance through insulation Tracking Resistance (Comparative Tracking Index) CTI >175 V DIN IEC 112/VDE 0303 Part 1 Isolation Group IIIa Material Group (DIN VDE 0110, 1/89) VDE 0884-10 INSULATION CHARACTERISTICS This isolator is suitable for basic electrical isolation only within the safety limit data. Maintenance of the safety data must be ensured by means of protective circuits. An asterisk (*) on a package denotes VDE 0884-10 approval for 848 V peak working voltage. Table 7.
