Functional

DC OK Relay Contact

(for DRS-24V100W1AR,

DRS-24V100W1NR)

30V / 1A, resistive load

The relay contact are normally “ON” (closed) when the output

(Vout) is greater than 75% of its rated value and “OFF”

(opened) when the output (Vout) is less than 75% typ.

**For power de-rating from < -10°C to -20°C, and 55°C to 70°C, see power de-rating on page 3.
