Input Voltage Range:
D48 = 36-75 Volts (48V nominal)
On/Off Control Logic:
N = Negative
P = Positive
Please refer to the Part Number Structure when ordering.
All specifi cations are typical at nominal line voltage and full load, +25°C unless otherwise noted. See
detailed specifi cations. Output capacitors are 1 µF ceramic multilayer in parallel with 10 µF electrolytic.
I/O caps are necessary for our test equipment and may not be needed for your application.
Regulation specifi cations describe output voltage deviations from a nominal/midpoint value to either
extreme (50% load step).
