Emerson eSure R48-2000e3 rectifier module
Emerson Network Power built one of the largest installed bases of telecom DC power equipment before Emerson Electric sold the division to Platinum Equity in 2016, which rebranded it as Vertiv. The R48-2000e3 is a 48V, 2000W rectifier from Emerson's eSure range, and enquiries for it are almost always a like-for-like module swap in an existing shelf rather than a system redesign.
How to read these part numbers
In the model designation R48-2000e3, R48 indicates a 48V DC output and 2000 the rated wattage; the eSure name distinguishes this rectifier family from Emerson's larger NetSure-branded modules. The module continued in production, unchanged in part number and specification, after Emerson Network Power's 2016 rebrand to Vertiv.

Ordering notes
Confirm the exact model and voltage class — a 48V eSure module is not interchangeable with a 24V rectifier of similar wattage. Condition is stated per quotation as new-surplus or refurbished, and where a destination does not admit used network equipment we quote new-build alternatives instead. Hardware only: any associated monitoring software or 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 confirm this on the quotation.
Lifecycle and availability
Emerson Network Power's power and cooling business was divested by Emerson Electric to Platinum Equity in 2016 and rebranded as Vertiv; the R48-2000e3 remained in production, unchanged, across that transition. This item carries an Emerson-era part number (BML440033/1) and is supplied as refurbished stock.

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 this the same product as a Vertiv rectifier?
Yes. Emerson Network Power's power business became Vertiv in 2016 after Platinum Equity's acquisition. The R48-2000e3 rectifier design and part number carried over unchanged, so an Emerson-branded module and a later Vertiv-branded one of the same part number are functionally identical.
Will this module fit any 48V rectifier shelf?
Only a shelf designed for the eSure/NetSure mechanical and connector format. Tell us the shelf model and we will confirm fit before quoting.
What condition is this unit supplied in?
It is refurbished, tested stock. We state condition — new, new-surplus or refurbished — on every quotation, and can source new-build equivalents where a destination requires new equipment only.
