Your rectifier is discontinued. Your network isn't.

VOLT48 keeps ageing and end-of-life 48V DC plants running — replacement rectifier modules, controllers and lithium retrofits for Eltek, Delta, Vertiv and other legacy systems across the GCC, MEA, India and Latin America. Send us the part number on the label and we'll tell you, within one business day, whether we can source it.

The situation

Recognise any of these?

Most of the calls we get start in one of three places. All three have a cheaper answer than the one you were quoted.

01

The module died and the model is gone

The rectifier was discontinued years ago. The OEM's answer is a full plant replacement, because that's the only thing left on their price list.

02

One failed module, a whole plant quoted

You need two rectifier modules. The offer on your desk is a new shelf, new controller and new commissioning — for a plant that still has years of service in it.

03

The batteries are finished, the plant is fine

Your VRLA bank is at end of life but the rectifier shelf is healthy. You don't need a rebuild — you need a lithium retrofit sized to what's already there.

Start here

Send us the label. We'll take it from there.

You don't need a drawing or a specification. A phone photo of the sticker on the failed module is usually enough for us to identify it, find a match and tell you what it costs.

What to send us

  1. The part numberPrinted on the front or the side of the rectifier module — something like FP2 48/2000 HE, R4850G2 or ESR-48/56.
  2. A photo of the shelfSo we can see the plant, the controller and how many slots you are actually running.
  3. Quantity and urgencyHow many you need, and whether the site is already down. That changes what we quote and how we ship it.

These are the families we are asked for most often — not a live stock list. Some sit in Dubai and ship in 24–48h; the rest we source to a stated lead time, and we always tell you which of the two you are getting. If your plant isn't listed, send it anyway: most legacy 48V systems are still sourceable.

What we do

Keep it alive, or replace it properly

From a single discontinued rectifier module to a full lithium battery bank — sourced, specified and supported by people who have actually run these systems.

Discontinued & Legacy Modules

Rectifier modules and controllers for plants the OEM has walked away from — Eltek, Delta, Vertiv, Emerson, Eaton, ZTE. Send the part number; we hunt it down.

Lithium Batteries for Telecom

48V LiFePO4 in 50–200Ah, 19" rack format with integrated BMS and RS485/CAN — supplied on their own, or as a drop-in replacement for a dying VRLA string.

New 48V DC Plants & Shelves

When the old plant genuinely is finished: rack-mounted rectifier systems, power shelves, controllers and DC distribution, sized to your load and your growth.

Edge & AI Data Center Power

Compact, modular DC power and backup for edge nodes, micro data centers and high-density AI sites — where the market is growing fastest.

Plant Audits & Part Identification

Independent DC plant audits, load and autonomy dimensioning, and a clear BOM. We tell you what you actually need — including when the honest answer is "nothing yet".

Global Sourcing & Supply

Direct access to vetted manufacturers in China & Taiwan with dual-sourcing and third-party QC — premium reliability without the premium markup.

Why VOLT48

The big OEMs sell you the next plant. We keep this one alive.

Huawei, Vertiv and Delta win the mega-projects — and once your system goes end-of-life, a new plant is the only thing left on their price list. Our incentive runs the other way: find the module, extend the asset, and say so plainly when it really is time to replace.

  • Real engineering, not a catalogue

    15+ years hands-on with rectifiers, controllers and battery banks. You talk to the expert, not a call center.

  • Speed that protects your SLA

    High-rotation modules are held in Dubai and ship in 24–48h. Everything else is quoted with a lead time we commit to. Either way you get an answer within one business day — including "we can't get this one".

  • Cost-efficient, not cheap

    Our pricing policy is 20–40% below premium-brand list on non-flagship applications, with the warranty in writing before you pay.

  • Independent & multi-brand

    No allegiance to one OEM. We specify what fits your network — and we can source it.

Our standard

No surprises on condition, date or price

Legacy parts are where buyers get burned. These are the four rules we hold ourselves to, in writing, on every single quotation.

01

New and new-old-stock only

We do not sell refurbished or pulled modules. Everything we quote is new or genuine new-old-stock, and we tell you which of the two it is before you order.

02

6-month warranty, in writing

Six months from delivery on every module and battery we supply. It is on the quotation before you pay — not buried in terms you find out about later.

03

In stock or on order — we say which

High-rotation modules sit in Dubai and ship in 24–48h. Everything else is sourced to a lead time we commit to up front. You never get a vague "soon".

04

Tested before it ships

Every module is powered up and checked against its rating before it leaves us. A part that arrives dead helps nobody — least of all the site that is already down.

From San José, California to Dubai — a global path in telecom & data center power
The story

15+ years powering networks — now from Dubai

It started in San José, California, managing containers of 48V DC rectifier systems for cellular towers and repeaters. From Delta/Ericsson to Eltek-Valere and Mean Well, across the US and Latin America, the work was always the same: keep critical infrastructure energized.

VOLT48 brings that hands-on expertise to one of the fastest-growing digital infrastructure markets on earth. The GCC is scaling data center capacity from ~1 GW to over 3 GW and densifying 5G — and every megawatt needs reliable DC power, batteries and someone who genuinely understands them.
