Input Fusing
Certain applications and/or safety agencies may require the installation of fuses
at the inputs of power conversion components. For DATEL BWR 3 Watt
DC/DC Converters, you should use slow-blow type fuses with values
no greater than the following:
VIN Range
"D5"
"D12"
"D48"
Fuse Value
1.5A
1A
0.5A
EMI RADIATED EMISSIONS
If you’re designing with EMC in mind, note that all of DATEL’s BWR 3 Watt
DC/DC Converters have been characterized for radiated and conducted emissions
in our new EMI/EMC laboratory. Testing is conducted in an EMCO 5305 GTEM
test cell utilizing EMCO automated EMC test software. Radiated emissions are
tested to the limits of FCC Part 15, Class B and CISPR 22 (EN 55022), Class B.
Correlation to other specifications can be supplied upon request. Radiated
emissions plots to FCC and CISPR 22 for model BWR-5/250-D12 appear below.
Published EMC test reports are available for each model number. Contact
DATEL’s Applications Engineering Department for more details.
