Inline CCTV Power Supply, 48V 2.5A, Inline Barrel, HAY-48V2.5A

Introduction: Meet the Inline 48V 2.5A CCTV Power Supply (HAY-48V2.5A)

The HAY-48V2.5A is an inline AC→DC power supply designed to deliver 48 V DC at up to 2.5 A (approximately 120 W) for CCTV installations, PoE NVR systems and PoC DVR devices. In a compact “brick” form factor with a DC barrel connector, this unit is intended for installers and integrators who need a tidy, dedicated 48 V feed without the bulk of a rackmount or DIN‑rail transformer. SKU: HAY-48V2.5A.

Key features at a glance

• Output:48 V DC, 2.5 A (nominal ≈120 W)
• Form factor:Inline/brick with DC barrel connector
• Intended use:CCTV, PoE NVR and PoC DVR power
• Compact.Useful where space is limited and a single inline adapter is preferred
• Practical guidance:Connector sizes and safety certificates should be confirmed before purchase and installation

Detailed specifications and benefits

Below is a clear view of the known specifications and the practical benefits they provide. Note that some technical data is not publicly available from all listings; installers should request the official Haydon datasheet and certifications prior to installation.

• Manufacturer:Haydon
• Model / Part:HAY-48V2.5A
• Distributor code:ITM003872
• Output voltage:48 V DC
• Output current:2.5 A
• Output power:Approximately 120 W (48 V × 2.5 A)
• DC connector:Listings are inconsistent — some references to 5.5×2.1 mm and other sizes; confirm with supplier

• Protections:Short‑circuit, overload and overvoltage protection details are not published on all listings — request official documentation for installation risk assessment.
• Certifications:Some distributors list the unit as tested to British safety standards; no universally available CE/UKCA/UL datasheet has been found — request certificates prior to sale or installation.
• Physical data:Dimensions, weight, cable length and warranty details are not consistently published — confirm prior to ordering.

• Compact and straightforward:Inline form factor keeps installations tidy where only one or a small number of devices need a 48 V feed.
• Dedicated 48 V output:Matching the typical voltage some PoE and PoC devices expect, reducing the need for step‑up converters or multiple adapters.
• Easy replacement and serviceability:If a single inline brick fails, it can be swapped quickly without affecting the rest of a system.

Use cases and scenarios where the HAY-48V2.5A excels

This inline 48 V supply is particularly useful in the following scenarios:

• For a single PoC DVR, PoE NVR module or an individual high‑voltage camera that requires a 48 V barrel connection, the HAY-48V2.5A delivers a neat, plug‑and‑play solution without running to a centralized rackmount feeding multiple outputs.

• When installing cameras in remote or distributed locations (e.g., outbuildings or small kiosks) where mounting a larger power cabinet is impractical, an inline brick is ideal for keeping the installation compact.

• For commissioning, testing or temporary setups where a quick, portable 48 V source is needed, the inline adapter makes swap‑in testing simple.

• In mixed environments where some devices require 48 V and others use 12 V or PoE, using single inline bricks can simplify wiring and isolate faults to one device rather than a common power bus.

Comparisons with similar products and alternatives

Choosing the right power solution depends on scale, complexity and serviceability requirements. Below are common alternatives and how the HAY-48V2.5A compares.

• Inline adapter (HAY-48V2.5A):Compact, low upfront cost, good for single devices or distributed deployments. Easier field replacement. Fewer outputs and less suited to powering many devices from one source.
• Rackmount / multi‑output supplies:Better for large installations, offering multiple fused outputs, centralised monitoring and hot‑swap capability. Higher initial cost and more complex installation; less convenient for remote single‑device sites.

• HAY-48V2.5A:Provides raw 48 V DC output for devices designed to accept a DC barrel plug or direct 48 V feed (PoC devices). Does not provide network data insertion like PoE injectors.
• PoE injectors / midspans:Combine data and power onto an Ethernet cable and are appropriate where both network connectivity and power are needed over a single cable. If devices accept PoE, injectors can be preferable; if a device requires a dedicated 48 V barrel plug, the HAY unit remains relevant.

• Well‑known power supply manufacturers (Mean Well, TDK, Delta, etc.) offer 48 V DC power bricks and DIN/rackmount units with well‑documented datasheets and global certifications. The HAY-48V2.5A can compete on size and simplicity, but buyers should request Haydon datasheets and certificates to match the compliance and features available from larger brands.

Conclusion: Why choose the HAY-48V2.5A?

The HAY-48V2.5A inline power supply is an attractive option when you need a compact, dedicated 48 V source for CCTV, PoE NVR, or PoC DVR applications. Its strengths are simplicity, portability and a lower price point compared with larger centralized solutions. For installers working on small sites, remote cameras or temporary deployments, the unit can be a practical choice.

That said, buyers should carry out due diligence prior to purchase: confirm the DC plug size and polarity, request the official Haydon datasheet for input voltage range, protection features and ripple/efficiency figures, and obtain certification files (CE/UKCA/UL or local equivalents) to ensure compliance with site regulations such as BS 7671 in the UK. If you require multi‑output power distribution, monitoring, or certified guarantees of performance and efficiency, consider rackmount or DIN power supplies from established manufacturers. For single‑device simplicity and convenient field replacement, the HAY-48V2.5A is a solid, cost‑effective option.
