SDU DC Series DIN Rail UPS System

The SDU DC Series from SolaHD is a DIN rail mounted uninterruptible power supply system designed for 24 VDC control and automation loads. It works in combination with a 24 VDC power supply and a battery module, monitoring the input voltage and switching to battery power without interruption when the supply fails. The DC UPS control unit manages battery charging, and status relay or LED outputs report buffering and battery condition so the controller can shut down gracefully. Compact housings fit standard 35 mm DIN rail inside control cabinets, and modules are available in several current ratings to match the load. Typical applications include PLCs, industrial PCs, network switches, sensors and process controls that must keep running through short power interruptions or ride through brownouts, as well as orderly shutdown systems.
