The VH-4032 is a no-switch always-on rack-mount power distribution unit purpose-built for 24/7 uninterrupted load scenarios in North American 19-inch server, surveillance and telecom cabinets. Featuring 6 NEMA 5-15R grounded outlets and no factory-installed master disconnect switch, it eliminates the risk of accidental manual power cuts for permanently active equipment.
Constructed from one-piece extruded aluminum for optimized thermal performance under nonstop operation, it is built on HI-SUN’s universal hot-swap modular platform, allowing field upgrades with switches, surge protection, metering and charging modules as needs evolve. Rated for 15A / 1800W at 125VAC and certified to NEMA, CE and RoHS standards, it is the ideal choice for always-on security systems, persistent server nodes and critical infrastructure across the US, Canada and Mexico.
1. Zero-Risk Always-On Unswitched Design
Unlike switched PDUs that carry the risk of accidental shutoff, this model has no built-in main power toggle, physically eliminating human-error power interruptions. It is purpose-engineered for round-the-clock critical loads such as surveillance cameras, life-safety systems and always-on server nodes, maximizing uptime continuity.
2. Native NEMA 5-15R North-American Grounded Receptacles
Six 15A NEMA 5-15R grounded outlets mate natively with standard North American equipment plugs, removing the need for bulky intermediate adapters. Full compliance with US and Canadian electrical norms ensures safe, code-ready deployment for commercial and industrial IT projects.
3. One-Piece Aluminum Chassis for 24/7 Reliability
Single-piece extruded aluminum construction delivers superior natural convection cooling compared to steel housings. Lower steady-state operating temperatures slow component aging during nonstop operation, extending service life, while lighter unit weight reduces static dead load on cabinet mounting rails.
4. Field-Upgradable Modular Architecture
Even as a base unswitched model, it comes with reserved modular bays. Users can add master switches, surge protection, power metering, overcurrent breakers or USB charging modules on-site at any stage, without scrapping the entire PDU — protecting initial investment while adapting to changing requirements.
5. Reversible 19" Rack Mount Compatibility
Standard 1U EIA form factor with adjustable side brackets supports both forward and reversed installation orientations. It fits all major brands of 19-inch server and network cabinets deployed across North America, requiring no on-site modification and streamlining integrator installation.
6. Dual Regional & Global Safety Qualifications
Certified to NEMA North American electrical benchmarks alongside CE and RoHS international standards, it meets mandatory qualification requirements for commercial, industrial and public-sector IT bids across the US, Canada and Mexico.

Q: How is VH‑4041 different from European Schuko or US NEMA PDUs?
A: VH‑4041 implements BS1363 13A shuttered British sockets and holds UKCA marking for 230V UK grid infrastructure. European Type‑E / Schuko PDUs and American NEMA PDUs use mechanically incompatible outlets designed for different regional power systems and cannot substitute for UK local deployments.
Q: Can I add surge protection or power‑metering after installation?
A: Yes. Thanks to hot‑swap modular architecture, SPD, meters and protection modules can be fitted on‑site without replacing the whole PDU, perfect for phased project upgrades common within UK commercial IT deployments.
Q: Does this satisfy compliance requirements for UK commercial tender projects?
A: Yes. It carries formal UKCA marking and complies with BS1363 socket standards, meeting typical qualification documentation requirements for British commercial and public‑sector bidding processes.
Q: Can it mount backwards for rear‑cable‑feed British‑style cabinets?
A: Yes. Adjustable side brackets support forward and reversed installation orientations, adapting for both front‑feed and rear‑feed rack‑wiring set‑ups widely seen across UK server hardware.
Q: Why use aluminium housing for UK closet‑style racks?
A: Extruded aluminium offers superior passive heat dissipation. Many British server closets have restricted airflow; improved thermal performance lowers internal operating temperatures and extends service‑life under continuous loads.
