As the standard baseline model in HI-SUN’s French Type E rack PDU lineup, the VH-4021 is engineered for mass-standardized 19-inch cabinet deployments across France, Belgium and French-speaking EU regions. It strikes an optimal balance of port count, cost and upgrade flexibility, featuring 8 NFC61-314 Type E earthed outlets, a front-panel illuminated master switch and a lightweight extruded aluminum chassis, delivering reliable 16A / 4000W power distribution for routine server, surveillance and office IT racks.
Built on HI-SUN’s universal modular platform, it supports field upgrades with surge protection, metering and charging modules without full unit replacement — protecting initial investment while meeting evolving project needs. Fully certified to CE, RoHS and French NFC standards, it is the cost-effective choice for bulk IT rollouts, standardized cabinet configurations and public-sector tender projects.
1. 8-Port Optimized Standard Configuration
Unlike 6-port models that run out of outlets for standard cabinets, or 9-port high-density units that leave unused sockets in light-load deployments, the 8-outlet layout is precision-matched to the typical device count of a standard 19-inch server rack. It eliminates both port shortage and wasted socket capacity, making it the default choice for standardized bulk cabinet configuration.
2. Lightweight Aluminum Chassis for Reduced Rack Load
The one-piece extruded aluminum housing cuts overall unit weight by nearly 30% compared to equivalent steel PDUs, reducing static dead load on cabinet mounting rails. Its natural convection design also dissipates operating heat passively, avoiding hot-spot buildup in densely packed rack rows.
3. Illuminated Front-Panel Master Switch
The red backlit main toggle delivers one-touch full-bank power shutdown for maintenance, while the integrated status indicator remains visible from across the server room — eliminating the need to crouch and verify power state at close range during routine inspections.
4. Universal Modular Compatibility for Investment Protection
All functional modules are 100% cross-compatible with the entire HI-SUN PDU ecosystem. Users can start with this base configuration and add surge protection, digital metering, leakage protection or USB charging modules at any stage, without discarding the original unit.
5. Reversible Mounting for Flexible Cabling
Adjustable side brackets support both front-facing and rear-facing installation orientations. This adaptability accommodates both front-feed and rear-feed cabinet wiring layouts, eliminating forced cable bends and simplifying on-site installation.
6. Full Local Regulatory Compliance for Tenders
Certified to CE, RoHS and French NFC61-314 electrical standards, it meets all mandatory qualification requirements for commercial, industrial and public-sector project bids across France and neighboring regions.

Q: Which French Type E PDU should I choose: VH-4021, VH-4022 or VH-4023?
A: Choose VH-4021 (8-port) for standard cabinet deployments seeking the best balance of cost and port count. Choose VH-4022 (9-port) for high-device-density cabinets to maximize outlets per rack U-space. Choose VH-4023 (6-port) for sites where built-in surge protection is mandatory.
Q: Can this base model be upgraded to surge protection later?
A: Yes. It shares the same modular bay design as all HI-SUN PDUs. Surge protection, metering and other modules can be installed on-site at any time without replacing the whole unit.
Q: Does it meet French local electrical standards for project bidding?
A: Yes. The Type E outlets comply with NFC61-314 French national standards, and the unit carries CE and RoHS certification, fully satisfying qualification requirements for local tenders.
Q: Can it be installed backwards for rear-cabling cabinets?
A: Yes. The adjustable mounting brackets support both forward and reversed installation, adapting to both front-feed and rear-feed cabinet wiring layouts.
