Safety Considerations
The EMS converters feature 1500 VDC isolation from 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
include UL60950 - CSA60950-00 and EN60950, although
other or additional requirements may be needed for
specific applications.
The EMS converter has no internal fuse. The external
fuse must be provided to protect the system from
catastrophic failure. Refer to the “Input Fuse Selection
for DC/DC converters” application note on www.power-
one.com for proper selection of the input fuse. Both input
traces and the chassis ground trace (if applicable) must be
capable of conducting a current of 1.5 times the value of
the fuse without opening. The fuse must not be placed in
the grounded input line, if any.
In order for the output of the EMS 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 EMS 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.
