Introduction to the Haydon HAY-PSU4/1-1/4A24 and its key features
Haydon HAY-PSU4/1-1/4A24is a purpose-built 24 VAC power supply designed for CCTV and security installations where reliability, configurability and simple protection are essential. Housed in a powder-coated steel enclosure, the unit can be configured either as four individual 1 A outputs or as a single consolidated 4 A output (total 4 A at 24 VAC). Each output is protected with an auto-reset PTC fuse and surge protection, and the PSU provides individual LED indicators for each output so installers can quickly verify power status.
At a suggested retail price of approximately 64.99, the HAY-PSU4/1-1/4A24 aims to strike a balance between professional features and cost-effective deployment for small-to-medium CCTV systems, access control peripherals and other 24 VAC devices used in security applications.

- Rugged enclosure and installation-friendly features:Powder-coated steel housing, multiple knockouts and a PG9 gland make mounting, cable entry and mechanical protection straightforward on small commercial or residential sites.
Use cases and scenarios where the HAY-PSU4/1-1/4A24 excels
The design and feature set of the HAY-PSU4/1-1/4A24 make it well suited to several practical security and CCTV scenarios:
- Multi-camera analogue CCTV systems:When feeding several 24 VAC cameras from a central location, the split-mode outputs let you isolate cameras per channel so a short on one camera wont take down the rest of the system.
- Small site security installations:Retail outlets, small offices, warehouses and non-critical campus sites that use 24 VAC-powered sensors or peripherals benefit from the compact, protected supply and the easy status indication for maintenance visits.
- Access-control and gate systems:Some access-control devices, gate motors or related control peripherals use 24 VAC for control circuits or heaters. The PSU can be configured to suit distributed loads or a single device draw.
- Replacement/retrofit projects:For legacy CCTV or alarm systems that still require 24 VAC supplies, this PSU provides an upgrade path with better protection (PTC and surge) and clearer diagnostics via LEDs.
- Professional DIY with qualified installation:The unit is compact and straightforward to wire but should be installed by a competent/qualified electrician in accordance with local wiring regulations.
Comparisons with similar products on the market
To choose the right power supply it helps to compare the HAY-PSU4/1-1/4A24 against other common alternatives in CCTV installations:
Many multi-output PSUs use conventional cartridge or blade fuses. While replaceable fuses provide clear fault isolation, they require spare parts and on-site replacement when blown. The Haydon units auto-reset PTC design avoids this maintenance overhead and reduces downtime after transient faults. However, replaceable fuses sometimes give a clearer permanent-fault indication (blown fuse still visible) whereas a PTC may mask intermittent issues until investigated.
Single-output transformers are simple and often cheaper for feeding one load, but they lack the flexibility and channel isolation of the Haydons multiple outputs. If you need to feed multiple cameras from a single box while preventing a short in one branch from affecting others, the HAY-PSU4/1-1/4A24 has the advantage.
Modern IP camera deployments increasingly use Power over Ethernet (PoE) or 12/24 V DC switch-mode supplies. PoE simplifies cabling and data/power integration, but its not suitable for legacy 24 VAC cameras or some specific control peripherals. Similarly, DC supplies are unsuitable for devices that require 24 VAC. The Haydon PSU remains relevant where legacy analog devices or specific AC-powered accessories are used.
If site uptime during mains failure is a priority, battery-backed PSUs or UPS systems are required. The HAY-PSU4/1-1/4A24 does not include integrated battery backup, so for failover youll need a separate UPS or battery inverter solution. For many small installations where mains reliability is good, the Haydon units protection and diagnostics are sufficient and more cost-effective.
Customer feedback and installer perspectives
There are no verified public customer testimonials supplied with the product text. However, based on typical installer feedback for products with similar feature sets, the following points are commonly appreciated:
- Reduced maintenance:Installers often highlight the convenience of auto-reset PTC protection because it reduces return visits to replace fuses following transient faults.
- Faster troubleshooting:Individual LED indicators are frequently praised for speeding up commissioning and fault-finding on multi-camera systems.
- Robust build:A metal, powder-coated enclosure with multiple knockouts and a PG9 gland is seen as durable and practical for professional installations.
- Value for money:At its suggested retail price, installers often view such a unit as good value compared with larger, more complex systems when only basic protected 24 VAC outputs are required.
Note: Always seek real customer reviews from reseller sites, installer forums or direct testimonials when making a purchasing decision.
Conclusion: why the Haydon HAY-PSU4/1-1/4A24 is a strong choice
The Haydon HAY-PSU4/1-1/4A24 is a practical, well-specified 24 VAC power supply tailored for CCTV and security installations that require both flexibility and protection. Its configurable output modes (four isolated 1 A outputs or one consolidated 4 A output), auto-reset PTC protection, surge protection and individual LED indicators make it particularly useful for multi-camera analogue systems, small security sites and retrofit projects where reliability and low maintenance are priorities.
While it does not include battery backup and is not a substitute for PoE or DC solutions where those are required, it fills a clear niche for 24 VAC-powered equipment. The robust steel enclosure and installer-friendly features add to its practicality on real-world sites. For installers and system designers working with 24 VAC devices, the HAY-PSU4/1-1/4A24 offers a competent, cost-effective and low-maintenance power distribution option—provided it is installed by a qualified electrician and used in accordance with the manufacturers datasheet and local electrical regulations.
Safety reminder:Refer to the manufacturer datasheet for full approvals and certificates. The supplied product text did not include sufficient data to confirm CE/UKCA or other conformity marks; always isolate the mains supply before installation and ensure a competent/qualified electrician carries out the wiring.
