SolaHD SDU Series DIN Rail DC UPS System products provide battery-backed power for industrial and commercial loads that must ride through outages, brownouts or other input-power disturbances.
Within the SolaHD UPS portfolio, DIN-rail SDU systems address control-panel and automation loads, while S4K and modular online platforms support higher-power rack or facility applications. UPS topology, DC bus or battery architecture, communication options and installation format vary by series.
Select the UPS by real load in watts and VA, input/output voltage and phase, required runtime, battery configuration, form factor, bypass needs, communications and environmental requirements - not by VA rating alone.
Online double-conversion UPS families continuously regenerate the output and are appropriate where power conditioning and transfer performance are critical. DIN-rail AC or DC UPS systems are often integrated directly with industrial control panels and require careful coordination with the control-voltage architecture.
Runtime depends on actual load and battery configuration. If external battery modules are supported, verify the exact battery family and quantity approved for the UPS model; batteries and communication accessories are not universally interchangeable between SolaHD series.
For replacement projects, also verify rack height or DIN-rail space, receptacle or terminal configuration, bypass method and network/serial communication requirements.
Provide the load watts/VA, input and output voltage, phase, required runtime, mounting format and any bypass or communication requirements.
No. Battery modules are series- and model-specific, so the UPS model and battery compatibility should be verified before ordering.
