
The product was submitted and evaluated for use at the maximum ambient temperature (Tma)
permitted by the manufacturer’s specification of: max. case temperature of 100°C
Engineering Conditions of Acceptability
For use only in or with complete equipment where the acceptability of the combination is determined by UL
LLC. When installed in an end-product, consideration must be given to the following:

The following secondary output circuits are SELV: All

The following secondary output circuits are at hazardous energy levels: All

The power supply terminals and/or connectors are: Not investigated for field wiring

The investigated Pollution Degree is: 2

Proper bonding to the end-product main protective earthing termination is: Required

An investigation of the protective bonding terminals has: Not been conducted

The following end-product enclosures are required: Mechanical, Fire, Electrical

The input to the DC-DC converter is intended to be supplied fro a TNV-2 or other non-hazardous
secondary circuit.

The DC-DC converters were evaluated with a fast acting Littlefuse Nano² Fuse rated 10A. A littlefuse
Nana² Fuse rated less than 10 A may be used in the application.

Basic Insulation is provided from input to output with a dielectric rating of 2250Vdc. ,
