A
Designs using the Si2400 pass all overcurrent and
overvoltage tests for UL1950 3rd Edition compliance
with a couple of considerations.
Figure 20 shows the designs that can pass the UL1950
overvoltage tests, as well as electromagnetic emissions.
The top schematic of Figure 20 shows the configuration
in which the ferrite beads (FB1, FB2) are on the
unprotected side of the sidactor (RV1). For this
configuration, the current rating of the ferrite beads
must be 6 A.
The bottom schematic of Figure 20 shows the
configuration in which the ferrite beads (FB1, FB2) are

on the protected side of the sidactor (RV1). For this
design, the ferrite beads can be rated at 200 mA.
In a cost-optimized design, it is important to remember
that compliance to UL1950 does not always require
overvoltage tests. It is best to plan ahead and know
which overvoltage tests will apply to your system.
System-level elements in the construction, such as fire
enclosure and spacing requirements, need to be
considered during the design stages. Consult with your
Professional Testing Agency during the design of the
product to determine which tests apply to your system.
