Only those products bearing the UL Certification Mark should be considered as being covered by UL's
Certification and Follow-Up Service.
Recognized components are incomplete in certain constructional features or restricted in performance
capabilities and are intended for use as components of complete equipment submitted for investigation rather
than for direct separate installation in the field. The final acceptance of the component is dependent upon its
installation and use in complete equipment submitted to UL LLC.
Look for the UL Certification Mark on the product.

Product Description
The Voltage Panel Mold 6123 BCMs and NBMs are a family of DC-DC converters that are designed for
building-in. The output voltage is an unregulated fixed turns ratio of the input voltage. The BCMs provide
insulation from input to output. The NBMs are non-isolating devices.
Model Differences
See Miscellaneous Enclosure for model nomenclature.
Technical Considerations
Equipment mobility : for building-in
Connection to the mains : not directly connected to the mains
Operating condition : continuous
Access location : for building-in
Over voltage category (OVC) : OVC II
Mains supply tolerance (%) or absolute mains supply values : 36-60 Vdc
Tested for IT power systems : No
IT testing, phase-phase voltage (V) : N/A
Class of equipment : Not classified
Considered current rating of protective device as part of the building installation (A) : N/A
Pollution degree (PD) : PD 2
IP protection class : IP X0
Altitude of operation (m) : Up to 5000 meters
Altitude of test laboratory (m) : less than 2000 meters
Mass of equipment (kg) : 0.042

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 investigated Pollution Degree is: 2
The following end-product enclosures are required: Mechanical, Fire, Electrical
The output of the BCM is separated from the input by Basic insulation and is considered SELV.
The output of the non-isolating NBM can be considered SELV if the input is SELV.
The BCM was evaluated with a Littelfuse 456 series fuse rated 40A max.
The NBM was evaluated without a fuse.
The output has not been evaluated for energy hazards.
See de-rating curves for maximum output current versus case temperature.
