Test Configurations  
Safety Considerations  
For safety-agency approval of the system in which the power  
module is used, the power module must be installed in com-  
pliance with the spacing and separation requirements of the  
end-use safety agency standard, i.e., UL60950, CSA C22.2  
No. 60950-00, and

BATTERY  
These converters have been evaluated to the spacing  
requirements for Basic Insulation, per the above safety stan-  
dards.  
VI(-)  
For Basic Insulation models ("–B" Suffix), 1500 Vdc is  
applied from VI to VO to 100% of outgoing production.  
Note: Measure input reflected ripple current with a simulated source  
inductance (LTEST) of 12µH. Capacitor CS offsets possible  
battery impedance. Measure current as shown above.  
For end products connected to –48 Vdc, or –60 Vdc nomianl  
DC MAINS (i.e. central office dc battery plant), no further  
fault testing is required.

Note:–60 V dc nominal bettery plants are not available in the  
U.S. or Canada.  
COPPER STRIP  
For all input voltages, other than DC MAINS, where the input  
voltage is less than 60 Vdc, if the input meets all of the  
requirements for SELV, then:

The output may be considered SELV. Output voltages will  
remain withing SELV limits even with internally-generated  
non-SELV voltages. Single component failure and fault  
tests were performed in the power converters.  
V

n
One pole of the input and one pole of the output are to be  
grounded, or both circuits are to be kept floating, to main-  
tain the output voltage to ground voltage within ELV or  
SELV limits.  
GROUND PLANE  
Note: Scope measurements should be made using a BNC socket,  
with a 10 µF tantalum capacitor and a 1 µF ceramic capcitor.  
Position the load between 51 mm and 76 mm (2 in and 3 in)  
from the module  
For all input sources, other than DC MAINS, where the input  
voltage is between 60 and 75 Vdc (Classified as TNV-2 in  
Europe), the following must be adhered to, if the converter’s  
output is to be evaluated for SELV:

The input source is to be provided with reinforced insula-  
tion from any hazardous voltage, including the AC mains.  
CONTACT AND

One VI pin and one VO pin are to be reliably earthed, or  
both the input and output pins are to be kept floating.

Another SELV reliability test is conducted on the whole  
system, as required by the safety agencies, on the combi-  
nation of supply source and the subject module to verify  
that under a single fault, hazardous voltages do not  
appear at the module’s output.

The power module has ELV (extra-low voltage) outputs  
when all inputs are ELV.  
Note: All voltage measurements to be taken at the module termi-  
nals, as shown above. If sockets are used then Kelvin con-  
nections are required at the module terminals to avoid  
measurement errors due to socket contact resistance.  
All flammable materials used in the manufacturing of these  
modules are rated 94V-0, and UL60950A.2 for reduced  
thicknesses. The input to these units is to be provided with a  
maximum 5A time-delay in the unearthed lead.
