Delta DPR 3000B-110 3kW 110Vdc Rectifier Module

The Delta DPR 3000B-110 is a 3kW, 110Vdc hot-plug rectifier module and the power module in the Delta DPS 3000 110V DC power system. Each module converts a single-phase AC supply to 110Vdc, charging the station battery and supplying the load. Up to five modules fit in one shelf, for 15kW.

The rectifier produces a regulated DC output for 110V and 125V nominal battery systems. The system controller sets and monitors each module over CAN bus, adjusting the output voltage for float, boost and equalise charging. In normal operation the rectifiers carry the standing load, and the battery takes over when AC is lost.

Modules in the same shelf share load within ±5% of maximum current. Three LEDs on the module front show its status at a glance, while detailed alarms and per-module data are reported to the Orion Touch controller over CAN bus.

Delta designed the DPR 3000B-110 for 110–125V battery systems in railway and metro, power utilities, and demanding industries such as marine, oil and gas, and process applications.

Adding capacity is a matter of fitting modules into empty slots in a DPS 3000 110V shelf, up to five for 15kW. The controller detects each new module and brings it into load sharing. One module more than the load needs gives N+1 redundancy: a 9kW load on four modules, for example, leaves 3kW spare. With a spare module on site, a failed unit can be swapped in minutes by hot-plugging, with no shutdown.
