| ● note.7 :
Specifications measured @23°C ambient. ● note.8 : Regulation specified after 15 minutes
of operation at set power level.
● note.9 : Individually fused FETs allow continued
operation with device failure.
● note.10 : Maximum operating power and current
may be reduced if operating conditions (ambient temperature, available air
flow, etc.)
cause internal load temperature to exceed safe operating conditions for
FETs (TEMP FAULT).
● note.11 : Maximum operating power and/or current
may be reduced when ambient temperature exceeds 25°C depending on air flow,
duty cycle of load operation and other conditions. |
