Operating Temperature
The ADNB 40W series start and operate within stated specifications at an ambient temperature from -25 OC to 70 OC
under all load conditions (see below derating curves for other amount of convectionand orientation. Derate output current
and power by 2.5% per degree above 50 OC. Maximum operating ambient temperature is 70 OC (which implies a 50%
derating at max 70 OC ambient).
Under convection cooling condition, the maximum output power derates linearly from full load. When input voltageis
90Vac, the maximum output power will derate to 90% full load.
