Delta EnergE DPR rectifier modules

Delta Electronics builds the EnergE rectifier line that appears in telecom power systems either under Delta's own brand or, since Delta's acquisition of Eltek, alongside Eltek Flatpack modules in the same shelf. Buyers usually need a DPR module matched by wattage and input phase to top up a shelf or replace a failed one, sometimes without being certain which of Delta's several wattage steps they actually have installed. This page lists the DPR modules from the compact single-phase units through the 10kW three-phase class.

How to read these part numbers

DPR model numbers give the wattage directly — DPR6000B-48 is a 6000W, 48V module — with the EnergE branding covering the current high-efficiency generation. Single-phase input (90-310VRMS) covers the 850W to 4500W modules; the larger 6000W and 10000W modules take 380/400/480VAC three-phase input. Confirm which your shelf is wired for before ordering, since a three-phase module will not run on a single-phase feed.

Ordering notes

State the exact DPR wattage and whether your installation is single- or three-phase, plus the shelf model it goes into — Delta's connector and mechanical envelope has changed across EnergE generations. Condition is stated per quotation — new, new-surplus or refurbished — and where a destination does not admit used network equipment (Algeria is the usual example) we quote new. Hardware only: software licensing remains between the buyer and the manufacturer. Destination type approval and import permits (CST/SABER, TDRA, ICASA, CA, CMC, ARPCE) are the buyer's responsibility and we will say so on the quotation.

Lifecycle and availability

The EnergE series is Delta's current rectifier generation and is sourced new in most wattages; older pre-EnergE Delta modules are supplied as surplus where still requested. Delta's 2022 acquisition of Eltek means the two brands now share some manufacturing and distribution — see our Eltek page for the Flatpack family.

Equipment condition

New — factory-sealed, supplied through the manufacturer's authorised channel or an authorised 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 an authorised 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.

Frequently asked questions

EnergE is Delta's branding for its current-generation high-efficiency rectifier family, covering the DPR modules from 850W to 10,000W. It replaced several older Delta rectifier lines.
