The VH-4002 is a compact 1U horizontal rack-mount power distribution unit factory-equipped with an integrated SPD surge protection module, featuring 5 standard IEC C13 output sockets for 19-inch server, network and monitoring cabinets. The built-in lightning surge suppressor instantly clamps transient voltage spikes, shielding switches, firewalls and storage devices from damage caused by thunderstorms and grid surges.Built on the same modular detachable architecture as the full HI-SUN PDU family, it supports field upgrades with interchangeable modules including digital meters, circuit breakers, RJ45 monitoring and USB chargers. Housed in a matte black all-metal chassis for stable heat dissipation and corrosion resistance, it installs quickly via standard 19-inch side mounting brackets. It is widely deployed in compact data centers, security control rooms, FTTH communication stations and commercial AV racks, with OEM customization of port count and mixed function modules available for bulk engineering projects.
1. Factory-Integrated SPD Surge Protection
Unlike basic PDUs that require separate surge accessory installation, the VH-4002 comes with a built-in surge suppression module as standard. It instantly absorbs instantaneous overvoltage from lightning strikes, grid fluctuations and switching transients, delivering out-of-the-box protection for valuable IT and network equipment.
2. Compact 5-Port IEC C13 Configuration
Equipped with 5 universal 10A 250VAC IEC C13 sockets, this 5-outlet layout is optimized for smaller rack deployments, branch circuits and semi-filled cabinets where an 8-port PDU would leave unused outlets wasting rack space. It matches all mainstream servers, routers and network hardware with C14 input plugs.
3. Standard 1U 19" Horizontal Rack Form Factor
Fits all EIA-standard 19-inch enclosures. Dual-side adjustable mounting brackets enable fast horizontal installation without extra conversion accessories, conserving vertical rack space for active equipment.
4. Fully Modular Hot-Swappable Architecture
All functional modules — amp/volt meters, overload protectors, remote monitoring ports — are fully hot-swappable. Users can freely configure additional PDU functions according to project safety and monitoring requirements, without replacing the entire unit.
5. Rugged Black Metal Chassis
Integrated stamped SPCC steel shell with electrostatic powder coating delivers excellent heat dissipation, scratch resistance and oxidation resistance, ensuring long-term reliable service in indoor data center environments.
6. Full Cross-Series Compatibility
The unified module standard matches all HI-SUN VH-series PDU accessories, enabling easy spare parts replacement and unified configuration across batches of cabinets.

Q: What is the main difference between VH-4002 and VH-4001?
A: The VH-4001 is an 8-port base model without built-in surge protection. The VH-4002 is a 5-port model that comes factory-integrated with an SPD surge protection module, making it ideal for smaller deployments where surge safety is a priority.
Q: What level of surge protection does this PDU provide?
A: The built-in SPD module clamps transient overvoltage and absorbs surge energy, protecting connected equipment from lightning-induced surges and grid switching transients. Detailed surge rating specifications are available on request.
Q: Can I add a digital meter and master switch to this PDU later?
A: Yes. All functional modules are hot-swappable. You can add metering, switching, leakage protection and monitoring modules on-site at any time without replacing the entire PDU unit.
Q: Will this fit all standard 19-inch server racks?
A: Yes. It is built to EIA RS-310 19-inch rack standards with standard side mounting brackets, and is compatible with all major brands of server, network and equipment cabinets.
Q: Can the port count and socket type be customized for bulk orders?
A: Yes. We support custom mixed configurations of C13 and C19 sockets, as well as custom outlet counts, to match specific project equipment layouts.
