2)
The efficiency curves are for 12 volt output models. To use for other models
adjust as follows:
±5 volt models subtract approximately 3%.
±15volt models add approximately 1%.
NOTES ON USING THE CURVES
1)
The input currents are for 20 watts of output power. For ±5 volt output models
the current is approximately 15% less.
