Safety
These converters are tested with 1500 VDC from input
to output. The input-to-output resistance is greater
than 10 MΩ. These converters are provided with Basic
Insulation between input and output. 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
In order to consider the output of the converter as
SELV (Safety Extra Low Voltage) or TNV-1, according
to IEC/EN 60950-1 and UL/CSA 60950-1, one of the
following requirements must be met in the system
design:
• Fuse: The converter has no internal fuse.
• If the voltage source feeding the converter is

external fuse must be provided to protect the
system from catastrophic failure. A fuse with a
rating not greater than 2.0 A is recommended. The
user can select a lower rating fuse based upon the
inrush transient and the maximum input current of
the converter, which occurs at the minimum input
voltage. 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.

considered SELV and may be grounded or
ungrounded.
transients, which exceed the input voltage. Even if
the input voltage is SELV (<60 V), the components
on the primary side of the converter may have to
be considered as hazardous. A safety interlock
may be needed to prevent the user from accessing
the converter while operational.

EMC Specifications
Conducted Noise:
The converters meet the requirements class A of
IEC/EN 55022 (conducted noise on the input
terminals) without any external components. The
results for this solution are displayed below.
To meet class B, it is necessary to fit a 5 μF ceramic
capacitor across the input terminals.
Electromagnetic Susceptibility:
* A denotes normal operation, no deviation from
specification. B denotes temporary deviation from
specification is possible.
