Description
The RS0400-Series front-end power supplies are specifically designed to operate as an integral part of a
complete distributed power system, with or without battery backup. A full complement of alarm and shutdown fea-
tures have been incorporated into the power supply to protect the system in the event of a fault condition. The
feature set makes this front-end power supply an excellent choice for applications requiring modular ac-to-dc bulk
intermediate voltages, such as distributed power and dc UPS.
