These power converters require a minimum 20% loading on each output to maintain
specified regulation. Operation under no-load conditions will not damage these devices;
Application-specific internal input/output filtering can be recommended or perhaps added
Devices can be screened or modified for higher guaranteed isolation voltages.

Floating Outputs
Since these are isolated DC/DC converters, their outputs are "floating." Any
BWR model may be configured to produce an output of 10V, 24V or 30V (for
±5V, ±12V or ±15V models, respectively) by applying the load across the
+Output and –Output pins (pins 3 and 5), with either output grounded. The
Common pin (pin 4) should be left open. Minimum 20% loading is recom-
mended under these conditions.
Filtering and Noise Reduction
All A-Series BWR 7-10 Watt DC/DC Converters achieve their rated ripple
and noise specifications without the use of external input/output capacitors.
In critical applications, input/output ripple and noise may be further reduced
by installing electrolytic capacitors across the input terminals and/or low-ESR
tantalum or electrolytic capacitors across the output terminals. Output
capacitors should be connected between their respective output pin (pin 3 or
5) and Common (pin 4) as shown in Figure 2. The caps should be located
as close to the power converters as possible. Typical values are listed in the
tables below. In many applications, using values greater than those listed
will yield better results.
In critical, space-sensitive applications, MPS may be able to tailor the inter-
nal input/output filtering of these units to meet your specific requirements.
