WattBox WB-400-8 8 Outlets Power Conditioner with Surge Protection

Rugged Power Conditioning for AV and Network Equipment

The WattBox WB-400-8 is an 8-outlet power conditioner made for AV racks, media cabinets, structured wiring areas, and network equipment that need cleaner protection than a basic power strip.

It is a strong fit for receivers, streamers, media players, routers, switches, control devices, small AV components, and connected electronics that benefit from surge protection, noise filtration, and a cleaner rack power layout.

Best Use Cases

• AV racks: Helps protect receivers, streamers, media players, processors, control gear, and small rack accessories.
• Media cabinets: Useful when several AV devices need cleaner power and better cable organization in one cabinet.
• Network closets: Good for routers, switches, modems, and low to mid-draw network devices that need protected AC power.
• Structured wiring areas: Helps organize power for smart home, networking, and low-voltage support equipment.
• Wall or cabinet installs: A practical choice when you need a durable mounted power conditioner without IP control or battery backup.

Who Should Buy This?

This is a good choice if you have several AV or network devices in one rack or cabinet and want more protection than a simple rack power strip. It makes sense when you need surge protection, EMI/RFI noise filtration, rear-facing outlets, a durable steel chassis, and flexible mounting.

It is especially useful for customers who want a clean, reliable power base for rack equipment but do not need app control, remote reboot, OvrC monitoring, outlet scheduling, or battery backup.

Who Should Not Buy This?

This is not the right product if you need battery backup during a power outage. It is a power conditioner and surge protector, not a UPS, so it will not keep equipment running when power goes out.

This is also not the right product if you need IP control, OvrC monitoring, self-healing reboot, outlet scheduling, or remote power cycling. For those features, choose a smart WattBox IP power conditioner instead.

This model also does not provide coax or Ethernet line protection. If your setup needs protection for coax, cable, satellite, phone, or Ethernet lines, choose a WattBox model that specifically includes those signal-line protection ports.

Installation Considerations

Before ordering, count the devices you want to protect and confirm that 8 outlets are enough. This model is best for small to medium AV racks, network cabinets, and structured wiring areas where the goal is cleaner protected AC power.

Plan the outlet layout before mounting. Rear-facing outlets help keep the rack cleaner, while spaced and rotated outlets can make it easier to connect larger plugs and power adapters.

Use the included tie-down straps to secure bulky adapters where needed. This can help reduce loose connections and make the rack easier to service later.

Use this power conditioner indoors in a dry location with a properly grounded outlet. Avoid extension cords, non-grounded adapters, appliances, heaters, laser printers, power tools, and other high-draw devices that do not belong on AV or network power protection.

Why This Is Better Than a Basic Power Strip

A basic power strip mainly gives you more outlets. The WB-400-8 adds a stronger protection layer with surge protection, Fireproof MOVs, EMI/RFI noise filtration, a steel chassis, and a cleaner mounting design.

For AV racks, media cabinets, and network equipment areas, that makes it a better fit than a loose consumer-grade strip sitting on a shelf or floor.

Why Noise Filtration Matters

AV and network systems often share power with many other devices in a home or business. Electrical noise can come from nearby electronics, motors, lighting, and other equipment on the same electrical system.

The WB-400-8 includes EMI/RFI noise filtration to help reduce electrical interference for connected equipment. That makes it a practical step up when the goal is cleaner power for AV and connected electronics.

When to Choose a Different WattBox Model

Choose a WattBox model with coax and Ethernet protection if your setup includes cable, satellite, modem, router, or signal-line connections that also need protection.

Choose a smart WattBox IP power conditioner if you need OvrC monitoring, remote reboot, outlet scheduling, self-healing auto reboot, or individual outlet control. Choose a UPS if the router, switch, NVR, modem, or other critical equipment needs to stay powered during outages.
