Electrical Characteristics: 25°C Tc, 28 VDC Vin, 100% load, unless otherwise specified.

Notes

1.Up to 90% of full power is available from either output

providing the total power does not exceed 30 watts.

2.The effect on the output voltage of either output (held at 3

watts) when the other output is varied from 3 to 27 watts.

3.A low output impedance power source is required on the

input to realize this start-up time. If less than full surge

current is available, start-up time will be longer
