What this product is
Architecturally, the DPS3000H-48 combines AC mains distribution, -48V DC distribution busbars, dual battery disconnect protection circuits, and an advanced supervision controller slot with four 50A rectifier bays. The internal topology utilizes isolated resonant conversion topologies supervised by real-time DSP logic, supporting full SNMP/RS485 telemetry and multi-stage low voltage disconnect (LVD) safeguards.
What problem it solves
Eliminates systemic power loss and brownout interruptions caused by unstable rural grids by operating down to 80V AC without dropping the load. It protects external lead-acid or lithium battery banks from destructive deep-discharge cycles through programmable electronic LVD contractors and eliminates network downtime via live hot-swappable module redundancy.
Who and where it is for
Engineered for 4G/5G cellular base stations, optical line terminal (OLT) aggregation centers, railway signaling communication shelters, and industrial automation supervisory control nodes.
