1U 12V 20A 18-Channel Rack Mount Power Supply – 12V

Quick take

This 1U rack-mount DC power distribution unit is built for 12V systems that need multiple outputs, like CCTV cameras and DVR-related setups. It offers 18 fused 12V ports, safety protections (including PTC reset fuse protection), and a clean-rack wiring layout with rear-facing connections. The main buying caveat is that it is meant for 12V DC loads only, and its port current mix (most at 3A, some at 5A) means you still need to match each camera or device to the right port rating.

Pros and cons

Pros

  • 18 fused 12V outputs for distributed power to multiple cameras/devices in one rack space.
  • Rear connection layout keeps the front of the rack cleaner than front-outlet designs.
  • Safety-focused design with independent PTC reset fuses plus surge and lightning protection.
  • LED status indicators make it easier to see powered-on status at a glance.

Cons

  • Only suitable for 12V DC power distribution, so it is not a fit for other voltages.
  • Current is split across port types (16 ports at 3A, 2 ports at 5A), so higher-draw devices require the right ports.
  • Some buyer feedback suggests occasional reliability or quality-control quirks with the indicator lights over time.

What buyers think

Reviewed productBuy on Amazon

Buyer-review evidence is moderately positive, with recurring praise focused on practical rack installation and day-to-day usability. Several buyers highlight that having the outlets on the rear keeps the front of the rack tidy, and that a single switch makes it straightforward to control power to connected components. Longer-term feedback is mixed but not alarming, with at least some buyers reporting minor quality-control issues related to indicator lights after extended use, while functionality still worked for them. Overall, the review themes point to this unit being a helpful “distributed power” hub for projects that need multiple 12V feeds in one rack space, with the main potential drawback being light/indicator reliability or workmanship consistency.

Who this 1U 12V 20A 18-channel power supply is best for

This power supply is a strong match if you are building or maintaining a security camera, CCTV, or other rack-based 12V DC system where multiple devices need power from a single, organized distribution point. It is especially useful when your wiring plan favors back-side terminations, since the ports are designed to connect from the rear, keeping the front panel uncluttered.

Key features that matter in real installations

18 fused 12V ports for distributed power

Instead of a single high-current output, this unit provides 18 separate DC outputs with fusing. That structure is meant to limit how faults on one port affect other connected devices, which is valuable in multi-camera installs where you want isolation and predictable behavior.

Port current mix: 16 x 3A and 2 x 5A

The overall capability is rated up to 12V at 20A, but the way the current is distributed across ports is not uniform. Sixteen ports are intended for 3A class loads, while two ports are rated for higher demand (5A). When planning your rack, map each device to a compatible port so the setup stays within the intended current limits.

PTC reset fuses plus surge and lightning protection

The design emphasizes protection and fault isolation using independent PTC reset fuses. It also includes surge and lightning protection, which can be relevant if your installation is in an environment where electrical transients are a concern.

LED status visibility and a centralized switch

Green LEDs indicate power-on status and help with quick visual checks. Buyers also like that power can be controlled as a group, using a single lighted switch rather than cycling individual devices.

Pros and cons, summarized

Reviewed productBuy on Amazon
  • Good fit for: rack-based 12V CCTV and camera systems needing 18 distributed feeds in a tidy 1U footprint.
  • Consider first if: you have a mix of device power draws and need to confirm which ports (3A vs 5A) match your cameras or accessories.
  • Worth it when: rear-facing cable management and per-port protection are priorities for your install style.

Verdict: is the 1U 12V 20A 18-channel rack mount power supply worth it?

It is a practical choice for installers and buyers who want a 1U rack-mount 12V DC power distribution unit with organized back-side connections and per-port protection. The biggest “make sure it fits” points are voltage compatibility (12V only) and matching device current needs to the 3A and 5A port mix. If your project aligns with those requirements, the usability benefits and multi-output design are likely to make this a convenient hub for CCTV-style rack builds.

FAQ

Reviewed productBuy on Amazon

What voltage does this power supply output?

It is designed for 12V DC output distribution. It is not intended for setups that require different DC voltages.

How many ports does it have, and are they all the same current rating?

It provides 18 fused 12V ports. The port current ratings are split, with 16 ports intended for 3A loads and 2 ports intended for 5A loads.

Is this suitable for CCTV and security camera systems?

Yes. It is specifically positioned for rack-mount security camera and CCTV style installations that require multiple 12V feeds from one unit.

Does it include surge and lightning protection?

Yes, it includes surge protection and lightning protection as part of its safety features.

Are the outputs controlled individually or together?

It uses a centralized, lighted switch for power control to the connected ports, rather than requiring you to operate power individually on each outlet.
