QMS DC-DC Series Data Sheet
Wide-Range Input, 70 to 82W Quarter-Brick Converters
Safety Considerations
The QMS converters feature 1500 VDC isolation from the
input-to-output. The input-to-output resistance is greater
than 10 M ? . These converters are provided with Basic
insulation between input and output circuits according to all
IEC60950 based standards. Nevertheless, if the system
using the converter needs to receive safety agency
approval, certain rules must be followed in the design of
the system. In particular, all of the creepage and
clearance requirements of the end-use safety
requirements must be observed. These documents
Conducted EMI
The following conducted EMI filter configuration and
component values are offered as a guideline to assist in
designing an effective filter solution in the actual
application. Many factors can affect overall EMI
performance; such as layout, wire routing and load
characteristics, among others. As a result, the final circuit
configuration and component values may require
adjustment.

The QMS converter has no internal fuse. The external
fuse must be provided to protect the system from
catastrophic failure. Refer to the “Input Fuse Selection

the grounded input line, if any.
In order for the output of the QMS converter to be
considered as SELV (Safety Extra Low Voltage) or TNV-1,

according to all IEC60950 based standards, one of the
following requirements must be met in the system design:
?
?
?
If the voltage source feeding the module is SELV or
TNV-2, the output of the converter may be grounded
or ungrounded.
If the voltage source feeding the module is ELV, the
output of the converter may be considered SELV only
if the output is grounded per the requirements of the
standard.
If the voltage source feeding the module is a
Hazardous Voltage Secondary Circuit, the voltage
source feeding the module must be provided with at
least Basic insulation between the source to the
converter and any hazardous voltages. The entire
system, including the QMS converter, must pass a
dielectric withstand test for Reinforced insulation.
Design of this type of system requires expert
engineering and understanding of the overall safety
requirements and should be performed by qualified
personnel.
