Test Configurations

Setup.
NOTE: All voltage measurements to be taken at the module
terminals, as shown above. If sockets are used then
Kelvin connections are required at the module terminals
to avoid measurement errors due to socket contact
resistance.

Design Considerations
Input Filtering
The power module should be connected to a low ac-
impedance source. Highly inductive source
impedance can affect the stability of the power
module. For the test configuration in Figure 16, a
33F electrolytic capacitor (ESR<0.1 at 100 kHz),
mounted close to the power module helps ensure the
stability of the unit. Consult your sales representative
for further applications guidelines.
Safety Considerations
For safety-agency approval of the system in which the
power module is used, the power module must be
installed in compliance with the spacing and
separation requirements of the end-use safety agency
standard, i.e., UL60950-1, CSA C22.2 No. 60950-1-
03, EN60950-1 and VDE 0805:2001-12.
These converters have been evaluated to the spacing
requirements for Basic Insulation, per the above
safety standards; and 1500 Vdc is applied from Vin to
Vout to 100% of outgoing production.
For end products connected to –48V dc nominal DC
MAINS (i.e. central office dc battery plant), no further
fault testing is required. For all input voltages, other
than DC MAINS, where the input voltage is less than
60V dc, if the input meets all of the requirements for
SELV, then:
The output may be considered SELV. Output
voltages will remain within SELV limits even with
internally-generated non-SELV voltages. Single
component failure and fault tests were performed
in the power converters.
One pole of the input and one pole of the output
are to be grounded, or both circuits are to be kept
floating, to maintain the output voltage to ground
voltage within ELV or SELV limits.
The power module has ELV (extra-low voltage)
outputs when all inputs are ELV.
All flammable materials used in the manufacturing of
these modules are rated 94V-0, or tested to the
UL60950 A.2 for reduced thickness.
The input to these units is to be provided with a
maximum 6.3 A very fast-acting surface mount fuse in
the unearthed lead.
