Linear power supplies have inherently low conducted and radiated noise levels.
EMI/RFI
For most system applications, these power supplies will meet the requirements
of FCC Class "B" and VDE 0871 for Class "B" equipment without additional
noise filtering.
Forced air. 20 CFM required for full rating Derate 30% for convection cooling.

*Note: Unit is shipped for 120V input from factory.
Mechanical Dimensions: inches (mm)
Note: I. LIM is factory set and should not be adjusted by users.
Application Note: User needs to provide earth ground to power supply with either solder to Tab or using washer and
nut assembly.
The SLT power supply is shipped from the factory with metal shorting straps connected between
the + OUT and + S terminals and the (-) OUT and (-) S terminals. This strapping configuration
allows the output of the SLS to be taken from either pair of terminals. This is the
standard configuration.
The remote sense feature is enabled by removing the shorting straps and connecting the
individual OUT and S terminals to the appropriate points of the load. If an OVP circuit is used it
should be connected to the + OUT and (-) OUT terminals. The OVP should never be connected
to the + S, - S terminals without the use of the shorting straps. In all cases it is critical that the
terminal screws be firmly tightened.
