Product Overview
The Delta DPR48/50-D DCE is a 2880W, -48 VDC hot-swappable rectifier module designed for telecom power systems and DC power plants that use the Delta DPR and DPS rack-mount platform. As authorized distributors, we supply the DPR48/50-D DCE as a drop-in replacement or expansion module for existing Delta DPS/ESR-48V rectifier shelves, hybrid power cabinets and -48V DC bus installations across telecom base stations, edge data centres and industrial control sites worldwide.
If you are evaluating the DPR48/50-D DCE alongside Huawei R4850 or Vertiv R48-3000E3 modules, the decision is usually driven by your existing cabinet platform. The DPR48/50-D DCE fits Delta DPR and DPS series shelves; it does not cross-fit Huawei TP48xxx, Vertiv NetSure 731 or Eltek Flatpack2 backplanes. For a full brand-by-brand mapping, see our 48V rectifier cross-reference chart.

Cabinet compatibility
The DPR48/50-D DCE is designed for Delta’s DPR and DPS series rectifier shelves and ESR-48V power systems. It is not mechanically or electrically compatible with:
- Huawei TP48200B / TP48300B / TP48400B / TP48600B (uses R4850 series)
- Vertiv NetSure 731 A41 / A91 (uses R48-3000E3 modules)
- Eltek Flatpack2 shelves (uses Flatpack2 48/3000 HE modules)
- ZTE ZXD2400 systems (uses ZXD2400 modules)
If your site already runs a Delta DPR or DPS shelf, the DPR48/50-D DCE is a direct plug-in. If you are migrating from another brand or building a greenfield site, choose the rectifier platform to match the cabinet and supervision controller you are standardising on. Our R4850 vs R48 selection guide covers the decision logic for the two dominant platforms; for Delta sites, the logic is the same — match the brand to the cabinet.
Typical applications
- Telecom base stations: -48V DC bus powering BTS radios, baseband units and transmission equipment in macro and small-cell sites
- Data centre standby: -48V DC UPS for edge data centres and telecom co-location rooms
- Industrial control: -48V DC supply for PLC cabinets, SCADA remote terminals and process control panels
- Solar-hybrid power systems: Rectifier charging stage in off-grid and weak-grid telecom installations with battery storage
The DPR48/50-D DCE at 2880W / 56A sits between the 3000W class (DPR48/50C, R4850N1) and the 1440W class (DPR48/30G), offering a balanced option for sites that need more current per module than the 30A class but do not require the full 3000W envelope.

Q: What is the Delta DPR48/50-D DCE rectifier module?
The Delta DPR48/50-D DCE is a 2880W, -48VDC hot-swappable rectifier module for Delta DPS/ESR 48V telecom power systems. It delivers 56A output current, supports wide-range AC input (90-300 VAC), active PFC with PF above 0.99, and CAN/RS485 digital monitoring. It is supplied by BS Comtec as an authorized Delta distributor with factory test reports and full warranty documentation.
Q: What is the price of the Delta DPR48/50-D DCE?
Pricing depends on quantity, destination and current factory pricing. As a 2880W-class module, the DPR48/50-D DCE is positioned between the 3000W class (Huawei R4850N1, Vertiv R48-3000E3) and the 1440W class (Delta DPR48/30G).

Q: Where can I get the Delta DPR48/50-D DCE datasheet?
Request the full datasheet from BS Comtec when you send an RFQ. The datasheet includes detailed efficiency curves, derating characteristics, communication protocol registers and mechanical drawings. We provide original factory documentation with every shipment. The specifications listed on this page are typical values; confirm exact parameters for your project from the official datasheet.
Q: Is the Delta DPR48/50-D DCE compatible with Huawei or Vertiv cabinets?
No. The Delta DPR48/50-D DCE is designed exclusively for Delta DPR/DPS series rectifier shelves and ESR-48V power systems. It does not fit Huawei TP48xxx cabinets (which use R4850 modules) or Vertiv NetSure 731 cabinets (which use R48-3000E3 modules). The mechanical form factor, backplane pinout, and communication protocol are all brand-specific. If you need a cross-reference mapping across brands, see the 48V rectifier cross-reference chart.
