Delta DPR 3000B-48 rectifier module — 3000 W, 48 V DC systems
- Model
- DPR 3000B-48
- Manufacturer
- Delta
- Output
- 54 V, 3000 W
The DPR 3000B-48 is the 3 kW module of Delta's EnergE rectifier series for 48 V telecom DC power systems. It is a 1U hot-plug unit: a 19-inch shelf holds five modules (15 kW) and a 23-inch shelf holds six (18 kW). The newer DPR 3000E-48 uses the same shelves at 98% efficiency, so our quotations state which of the two is offered.

Before you order
State the exact DPR wattage, whether the installation is single- or three-phase, and the shelf model the module goes into: Delta's connector and mechanical envelope has changed across EnergE generations. We quote new, new surplus and tested refurbished units as separate lines, state the condition and origin of every unit on the quotation, and confirm compatibility from the details you give before you commit.
Equipment condition
New — factory-sealed, supplied through the manufacturer's own channel or a qualified distributor, with full manufacturer warranty.
New surplus — unused factory stock, original packaging where available, sourced from decommissioned projects or distributor inventory. Manufacturer warranty may have lapsed; CRS PLUS warranty applies.
Refurbished / tested — previously deployed equipment, cleaned, firmware-checked and functionally tested against the manufacturer's specification before shipment. CRS PLUS warranty applies.
Condition is confirmed in writing on every quotation before you commit to an order.
Warranty
Warranty terms vary by item, by condition and by the supplier the equipment is sourced from. They are stated in writing on the quotation, per line item, before you commit to an order.
Where equipment is supplied new through the manufacturer's own channel, the manufacturer's warranty applies and is passed to you.
Send us the part numbers you need and we will confirm warranty terms alongside availability, condition, lead time and price.
Questions
Frequently asked questions
Is the DPR 3000B-48 interchangeable with the DPR 3000E-48?
The DPR 3000E-48 is the newer 98% efficiency version and uses the same 1U shelves as the DPR 3000B-48. Whether the two can be mixed in one system depends on the controller and shelf revision, so give us the system model when you enquire.
How many DPR 3000B-48 modules fit in one shelf?
Five in a 19-inch 1U shelf (15 kW) and six in a 23-inch 1U shelf (18 kW).
What is the price of the Delta DPR 3000B-48?
CRS PLUS does not publish list prices: the price of each item depends on its condition (new, new surplus or refurbished), the quantity and the destination. Send the part number and quantity through the form on this page and a structured offer follows within 72 hours, with price, condition and lead time stated per line.
What is the lead time for the Delta DPR 3000B-48?
Lead time depends on where stock is held at the time of your enquiry, so it is confirmed per line on the quotation, together with the condition of each unit. Items that are no longer in production are quoted as new surplus or as tested refurbished units.
Can CRS PLUS propose an alternative if a part number is discontinued or unavailable?
Yes. Where a part cannot be found in the quantity required, our engineers propose an equivalent that delivers the same function from parts that are available, and state the trade-offs in writing before you commit.
