The VH-4003 is a 1U horizontal high-power industrial rack PDU purpose-built for heavy-load telecom, industrial automation and high-density data center 19-inch server cabinets. Built to the international IEC 60309 industrial connector standard, it delivers stable 32A high-current output with a total power capacity up to 8000W.Unlike standard IT-grade PDUs with SPCC steel housings, it features a rugged aluminum alloy chassis for superior thermal dissipation under sustained high loads. It is fully compatible with HI-SUN’s full ecosystem of modular functional modules, including master switches, overload breakers, SPD surge protection and digital monitoring meters. Certified to CE and RoHS standards, it provides centralized, safe power distribution for high-power network equipment, industrial controllers and communication hosts, suitable for global engineering export projects.
1. IEC 60309 Industrial High-Current Standard
Equipped with a 32A blue industrial input plug and 6 matched industrial output sockets with IP44 dust and water-resistant covers, it supports up to 8000W total power delivery. This industrial-grade connector system is purpose-built for heavy-load industrial and telecom power demands, delivering higher current capacity and better environmental resistance than standard IEC C13/C19 IT connectors.
2. Aluminum Alloy Chassis for Enhanced Heat Dissipation
Constructed from high-grade aluminum alloy rather than conventional SPCC steel, the housing delivers significantly better thermal conductivity. It efficiently dissipates heat generated by continuous high-current operation, reducing internal temperature rise and extending component service life — a critical advantage for 24/7 heavy-load industrial deployments.
3. Fully Modular Hot-Swappable Architecture
All control, protection and monitoring modules are fully hot-swappable. Users can freely configure master power switches, overload protection, lightning surge suppressors, digital volt-ampere meters and RJ45 remote monitoring modules according to specific project safety and operational requirements, without replacing the entire PDU.
4. Multi-Layer Comprehensive Electrical Safety
Optional overload circuit breakers, SPD surge lightning protection and leakage protection modules effectively guard against overcurrent, surge voltage and electric leakage hazards, protecting high-value industrial and communication equipment from electrical damage.
5. Standard 1U 19" Rack Mount Design
The standard 1U height fits all EIA-compliant 19-inch server and equipment cabinets. Adjustable dual-side mounting brackets enable fast horizontal installation without extra adapters, optimizing vertical rack space utilization.
6. Global Certifications & Custom Engineering Support
Certified to CE and RoHS international standards, it meets market access requirements for the EU and global regions. Bulk orders support full customization including socket quantity, cable length, housing color and silk-screen brand logo to match project specifications.

Q: What is the main difference between VH-4003 and standard C13 rack PDUs?
A: The VH-4003 is an industrial-grade 32A high-power PDU using IEC 60309 industrial connectors with IP44 protection, delivering up to 8000W total power. Standard C13 PDUs are IT-grade 10A/16A units designed for general server equipment. The VH-4003 is built for heavy-load industrial and telecom scenarios.
Q: Why use an aluminum alloy housing instead of steel?
A: Aluminum alloy has significantly higher thermal conductivity than steel. It dissipates heat far more effectively during continuous high-current operation, reducing internal temperature rise and improving long-term reliability — especially important for 24/7 industrial deployments.
Q: Can the number and type of output sockets be customized?
A: Yes. We support custom socket counts and mixed connector configurations for bulk project orders, to match specific equipment layouts and power requirements.
Q: What is the protection rating of the sockets?
A: The IEC 60309 industrial sockets feature IP44 dust and water-resistant covers, providing basic environmental protection suitable for semi-industrial and sheltered outdoor cabinet environments.
Q: What certifications does this industrial PDU hold?
A: The VH-4003 series is certified to CE and RoHS standards, meeting international safety and environmental requirements for industrial and telecom equipment.
