This Pre‑Built Switched‑Overload Global Modular Rack PDU is a 19‑inch 1U horizontal rack‑mount power distribution unit, designed for repeat‑spec cross‑border cabinet roll‑outs and export‑oriented system integrators. Distinct from bare‑base VH‑4089 (zero pre‑installed control hardware, full on‑site module assembly required) and factory‑SPD‑focused VH‑4091 (built‑in surge priority), this unit is factory pre‑integrated with illuminated master switch plus push‑button resettable overload protection. Customers select target‑market native‑standard sockets at time‑of‑order and receive ready‑to‑deploy hardware, cutting field‑assembly labour.
Built‑upon unified hot‑swap modular architecture, it reserves auxiliary slots for post‑installation upgrades including surge suppression, power metering and communication modules. Rated for 16A / 4000W @250VAC, CE & RoHS certified, compliant with EIA‑19‑inch rack norms. It fills the gap between fully‑custom bare chassis and fixed‑single‑country PDUs for medium‑volume multi‑national standard‑spec deployments.
Core positioning: Factory pre‑integrated switch+over‑load ready‑to‑run global‑modular PDU; order‑time configurable regional native sockets; no mandatory on‑site core‑module fitting, still retains future hot‑swap expandability for multi‑nation repeat‑order cabinet projects.
1.Factory‑Completed Switch‑Overload Assembly Eliminates On‑Site Core‑Module Work
Most universal‑modular PDUs force integrators to assemble control‑protection modules on‑site. Improper field installation raises hidden contact‑fault risks. VH‑4090 finishes master‑switch and overload‑breaker assembly and electrical impulse testing inside factory. Upon delivery, technicians skip complex core‑hardware fitting and only complete rack mounting & mains wiring. It shortens cabinet‑commissioning cycles for multi‑country repeat‑volume orders.
2. Order‑Time Pre‑Configured Native National‑Standard Sockets
Instead of compromise‑type multi‑hole universal combo sockets with poor plug‑fit, you specify destination‑market socket standard during ordering, and sockets are pre‑installed at manufacturing phase. Supports Schuko, Type‑E, CEI, SANS, NEMA, BS‑1363 and more. Delivers genuine regional‑spec receptacle performance right out‑of‑box for export cabinet shipments, removing adapter‑reliance and tender‑non‑compliance risks.
3. Preserved Hot‑Swap Expandability For Phased Project Evolution
Even though core switch‑over‑load function is factory‑built, reserved auxiliary bays stay available. As site‑conditions change — such as adding surge hardware for thunder‑risk territories or deploying metering for capacity audits — technicians hot‑fit extra modules post‑deployment, no full‑rack power‑cut or PDU‑body swap‑out needed. Balances “ready‑to‑ship convenience” and “future‑upgrade flexibility”.
4. Optimised For Medium‑Volume Repeat‑Spec Global Roll‑Out Workflows
Global integrators frequently handle batches of identical‑spec cabinets shipped to different countries. VH‑4090 adopts unified base chassis, only swapping pre‑fitted socket modules per destination. This simplifies internal procurement workflows: maintain one base‑part‑number framework, only adjust socket selection per order. Compared with purchasing separate country‑locked PDUs for each territory, it lowers part‑number management overhead.
5. Versatile Multi‑Orientation Mounting For Worldwide Diverse Cabinet Hardware
Complete TP‑series adjustable bracket kit ships as‑standard. Beyond standard horizontal 19‑inch racks, it supports vertical wall‑mount and custom shelter‑enclosure fitting, coping with non‑standard export cabinets, remote telecom shelters and retail‑site back‑of‑house enclosures encountered across global projects.
6. Bundled Compliance Paperwork Streamlines Multi‑Nation Tender & Customs
Each unit comes with chassis safety‑test‑report plus pre‑fitted‑socket‑module compliance documentation bundled together. This avoids integrators manually collating separate‑component documents, speeding‑up customs‑clearance and tender‑audit submission for cross‑border bidding‑projects. OEM silkscreen marking available for bulk‑order private‑label reseller inventory programmes.
Deployment note: Pre‑installed master‑switch and overload handle main‑bank protection. For locations exposed to frequent lightning‑strike risk, order additional SPD hot‑swap retrofit‑module according to local national electrical‑installation regulations.
Compared with VH‑4089 (base modular international PDU):
1.Pre‑assembled control + protection out of the box: VH‑4090 ships with factory‑installed master switch and overload protection. VH‑4089 is the base fully‑configurable model with no pre‑installed functions, requiring separate module selection and installation. VH‑4090 offers a faster, simpler solution for standard projects.
2. Optimized for standard rollouts: Targeted at repeatable, standard‑spec global deployments where control and overload protection are required. VH‑4089 is optimized for fully‑customized large‑scale projects.
Compared with ordinary fixed‑function global PDUs on the market:
1.Configurable sockets + modular expandability: Most competing universal PDUs have fixed universal sockets and fixed functions. VH‑4090 offers dedicated national‑standard sockets configured to order, plus modular upgrade capability for surge, metering and more.
2. Out‑of‑box safety + control: Many rival basic global PDUs only offer power distribution with no control or protection. VH‑4090 includes factory‑built switch and overload protection, delivering immediate operational safety and convenience.
3. Extensive mounting accessory range: Comes with a full line of TP‑series adjustable brackets. Most competing products only supply basic fixed mounting ears, limiting installation options for non‑standard cabinets.
1. Multinational‑chain office standard‑spec IT‑closet roll‑outs: Chain‑enterprise branch‑office cabinet batches shipped to multiple nations; factory pre‑built switch‑over‑load + destination‑specific sockets cut on‑site assembly work.
2. Export‑prefabricated cabinet OEM turn‑key orders: Cabinet‑manufacturers delivering finished racks to overseas buyers; ready‑configured PDU reduces end‑customer integration burden.
3. Small‑medium global‑branch server‑room deployments: Regional enterprise satellite‑site racks requiring baseline local power‑isolation and overload‑safety without full‑custom‑chassis expense.
4. International hotel & retail‑chain back‑of‑house cabinet hardware: Worldwide retail/hotel sites requiring consistent baseline power‑safety configuration, with sockets matched to each country.
5. Cross‑border system‑integrator standard‑spec tender‑projects: Bidding documents specify mandatory master‑isolation plus overload‑protection, while requiring local‑nation socket compliance.
6. Mid‑volume global telecom‑edge‑site deployments: Remote edge‑nodes needing baseline power‑safety, with possibility to add surge / metering modules later as site‑assessment updates.

Q1: What is the main difference between VH‑4090 and VH‑4089?
A: VH‑4089 is the base fully‑modular model with no pre‑installed control or protection functions, for fully customized projects. VH‑4090 comes with factory‑preinstalled master switch and resettable overload protection, offering an out‑of‑box solution for standard deployments. Both support configurable national socket standards.
Q2: Can I choose the socket standard for my target country?
A: Yes. You can select from German Schuko, French Type‑E, Italian CEI, Danish SB, South African SANS, US NEMA, UK BS and other national standards to match your deployment region.
Q3: Can I add surge protection or power metering later?
A: Yes. The hot‑swap modular design supports on‑site installation of DY‑series SPD surge modules or DB‑series metering modules, with no need to replace the main PDU body.
Q4: Is the VH‑4090 compatible with standard 19‑inch racks worldwide?
A: Yes. It follows the EIA 19‑inch 1U global rack standard, compatible with most mainstream server and network cabinets used in countries around the world.
Q5: Does it fit non‑standard custom export‑cabinets?
A: Full TP‑series multi‑purpose bracket‑kit is supplied, supporting vertical wall‑mount and custom‑shelter mounting beyond standard horizontal 19‑inch rack installation.
Q6: Do you support custom cable lengths and OEM branding?
A: Yes, custom cord length and OEM silkscreen branding are available for MOQ bulk project orders. Please contact our sales team with your specific requirements.
