Typical Characteristics
Performance Characteristics; Vin =48 V (See Note A)
(Refer to typical application for output configuration)
Note A:
All Characteristic data in the above graphs has been developed from actual products tested at 25°C. This data is considered typical data for the ISR.
Note B:
SOA curves represent operating conditions at which the internal components are at or below the manufacturer’s maximum rated operating temperatures.
PT4711 Safe Operating Area (SOA) (See Note B)
(All outputs proportionally loaded from 0 to 100 % of full load)
