DC OK Relay Contact 30V / 1A
The relay contact are normally “ON” (closed) when the output
(Vout) is greater than 90% of its rated value.
**For power de-rating from 40°C to 70°C @ 115Vac & 50°C to 70°C @ 230Vac, and Vin < 100Vac, see power de-rating on page 3.
***PARD is measured with an AC coupling mode, 5cm wires, and in parallel with 0.1μF ceramic capacitor & 47μF electrolytic cap
acitor.
