Design Considerations
Input Source Impedance
The power module should be connected to a low
ac-impedance source. A highly inductive source
impedance can affect the stability of the power module.
For the test configuration in Figure 61, a 33F
electrolytic capacitor (ESR<0.7
at 100kHz), mounted
close to the power module helps ensure the stability of
the unit. Consult the factory for further application
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., UL 1950, CSA C22.2 No. 60950-00, and VDE
0805:2001-12 (IEC60950 3
rd Ed).
If the input source is non-SELV (ELV or a hazardous
voltage greater than 60 Vdc and less than or equal to
75Vdc), for the module’s output to be considered as
meeting the requirements for safety extra-low voltage
(SELV), all of the following must be true:
The input source is to be provided with reinforced
insulation from any other hazardous voltages, including the
ac mains.
One VIN pin and one VOUT pin are to be grounded, or both
the input and output pins are to be kept floating.
The input pins of the module are not operator accessible.
Another SELV reliability test is conducted on the whole
system (combination of supply source and subject
module), as required by the safety agencies, to verify that
under a single fault, hazardous voltages do not appear at
the module’s output.
Note: Do not ground either of the input pins of the
module without grounding one of the output pins.
This may allow a non-SELV voltage to appear
between the output pins and ground.
The power module has extra-low voltage (ELV) outputs
when all inputs are ELV.
For input voltages exceeding –60 Vdc but less than or
equal to –75 Vdc, these converters have been evaluated
to the applicable requirements of BASIC INSULATION
between secondary DC MAINS DISTRIBUTION input
(classified as TNV-2 in Europe) and unearthed SELV
outputs (-B option only).
"All flammable materials used in the manufacturing of
these modules are rated 94V-0 and UL60950 A.2 for
reduced thicknesses. The input to these units is to be
provided with a maximum 3A fast-acting fuse in the
unearthed lead."
