Summary

Siemens 6EP1931-2FC21 SITOP DC UPS module designed to provide reliable 24VDC uninterruptible power for industrial control and automation systems. Provides up to 40A output and operates with an external battery module for backup power during supply interruptions.

This was part of a custom electrical/electronics cabinet that was mounted on a yacht. As the cabinet was customized for the exact application on this vessel, we have disassembled/parted the cabinet out. All parts were reported to be working, but we lack the proper equipment to test them and confirm this. As such, we are selling them as working with a 30 day period for customers to test and ensure functionality and a 90 day warranty for peace of mind.

This is a multiple quantity listing and the unit that you will receive may be different than the unit shown, but is in the same cosmetic condition.

Listing is for Module only, does not include any instructions, installation screws, or original box.
