• Manufacturer Part Number: S15-48-12
• Description: 48Vin 12Vout 1.25A
• Manufacturer: BTCPOWER [Broadband TelCom Power, Inc.]

Technical Specification
S15-48-12
Dynamic Response
The dynamic response of the unit at load step is
shown in Fig 12. The output load current change
from 50% to 75% and return to 50% at the slew
of 0.1A/ s. The input is 48V and a filter of 10 F
tantalum capacitor and 1 F ceramic capacitor is
used parallel to the output.
Ripple and Noise
The output voltage waveform has been measured
at full load condition, with 10 F tantalum
capacitor plus 1 F Ceramic capacitor closely
parallel to the unit’s output. Fig 13 shows the
output ripple and noise waveform.
Thermal De-rating
For thermal de-rating, output current vs. ambient
temperature and airflow rates has been tested,
and the test results are given in Fig 14.
Ambient temperature varies between 55 C and
90 C with the airflow of 0, 100 and 200LFM (0,
0.5m/s and 1m/s).
Others
Other curve and waveforms presented include
output voltage vs. current curve (Fig 15) and
input current ripple waveform at full load condition
(Fig 16).
