Benefits explained:
- Individual auto-reset PTC protection:Traditional fused power supplies require fuse replacement when an output is overloaded. PTCs reset automatically after an overcurrent event clears, reducing maintenance visits and downtime. For camera installations, this means transient short-circuits or faults on a single cable don’t force a technician to replace fuses or power-cycle the entire rack.
- LED indicators per output:Quick visual confirmation of which output is live or in fault helps speed up fault-finding during service calls.
- LCD monitoring:The front-panel readout for voltage and current lets installers verify supply condition at a glance and detect abnormal draws that may indicate camera failure or cabling issues.
- Regulated, filtered & surge-protected outputs:These features reduce the risk of image noise, false alarms and premature equipment failure caused by voltage spikes and electrical interference — especially important in environments with heavy electrical loads or frequent lightning activity.
- Compact 1U rack form:Saves valuable rack space in equipment cabinets while centralising power distribution for tidy cable management and simplified maintenance.
Use cases and scenarios where this unit excels
The Haydon 16‑way PSU is well suited for a wide range of CCTV and security system deployments where multiple 12 V devices must be powered from a central rack. Typical scenarios include:
- Retail and small commercial premises:Single-site retail stores, small shopping centres and offices where up to 16 analogue or 12 V cameras are required. The 1U chassis keeps the equipment cabinet compact while providing clear fault indicators for quick on‑site checks.
- Multi-dwelling or residential installations:Apartment blocks or housing estates with moderate camera counts benefit from centralised power in a shared comms cabinet; auto-reset protection is useful where immediate physical access for maintenance may be limited.
- School and campus deployments:Classrooms, corridors and outdoor perimeters often use many discrete 12 V cameras — monitored outputs and a central LCD make scheduling maintenance and diagnostics easier for on‑site engineers.
- Warehouse and logistics hubs:Facilities with multiple interior and exterior cameras can rely on the regulated and surge-protected outputs to maintain image stability despite heavy machinery and electrical interference in the environment.
- Temporary or event installations:Portable CCTV racks for events or site security where quick set-up, robust protection and minimal maintenance are priorities.
Note on camera compatibility: many 12 V analogue-dedicated cameras draw in the region of a few hundred milliamps during normal operation. The per-output rating of 1.35 A supports most cameras including those with modest IR illumination, but high-draw devices (heavy heaters, large IR arrays, or devices with additional accessories) should be checked against the per-output and total current limits to avoid overloading.
Comparisons with similar products in the market
When choosing a multiway rack power supply, integrators often weigh a number of factors: per-output protection type, total capacity, indicators and monitoring, surge protection, and physical footprint. Here is how the Haydon unit compares on common points:
- Auto-reset PTC vs mechanical fuses:Many competing units use replaceable blade or glass fuses that require physical replacement when blown. Haydon’s PTC approach reduces service visits and keeps single-output faults from creating spares-management overhead.
- Monitoring and indicators:Some budget multiway PSUs provide only power rails with no per-output LEDs or system readouts. The inclusion of an LCD plus individual LEDs positions the Haydon PSU as more service-friendly — beneficial for systems where uptime and rapid troubleshooting are priorities.
- Total power and scalability:With 16 A total and sixteen outputs, the Haydon PSU targets small-to-medium installations. For very large sites or where many high-current devices are used, larger supplies (e.g. 30–60 A rack PSUs) or distributed power architectures may be required. For what it is intended to do — powering up to 16 cameras with independent protection — the Haydon provides a balanced specification.
- PoE alternatives:Power-over-Ethernet (PoE) switches deliver both data and power to IP cameras and are often chosen for modern IP systems. The Haydon PSU is aimed primarily at 12 V DC devices (analogue cameras, some IP camera models with external DC input). In hybrid systems it complements PoE infrastructure where non-PoE devices remain in use.
- Price-to-features:At the suggested price (RRP suggested at 199.00 with a cost price shown as 166.44), the unit offers a competitive combination of monitoring, protection and rack-friendly design. Confirm currency and VAT specifics when comparing with other suppliers.
Customer feedback and typical installer impressions
While individual public reviews for every part number are not always available, common feedback themes from installers and systems integrators working with similar multiway rack PSUs and with Haydon products typically include:
- Reliability and uptime:Users report that auto-reset protection reduces the need for site visits and keeps systems running during transient faults.
- Simplified troubleshooting:The combination of per-output LEDs and an LCD readout speeds fault diagnosis in the field, especially where multiple cameras are connected to the same rack.
- Space-saving:The 1U form factor is praised where rack space is at a premium.
- Practical limitations noted:Installers sometimes caution that the 1.35 A per-channel rating means the supply is not suitable for unusually high-draw devices on a single output, and recommend planning to distribute heavy loads or use devices with external regulators if needed.
These are aggregated impressions based on installer experience and common industry commentary rather than verbatim customer quotes for this exact SKU. For specific customer reviews, check reseller pages or request references from your supplier.
Conclusion — why choose the Haydon HAY-RMPSU1612-16A/1U?
The Haydon 16-way 12 V rack-mount power supply delivers a practical, well-balanced solution for small to medium CCTV and security racks. Its combination of sixteen individually protected outputs, per-channel LED indicators, an LCD for voltage/current monitoring and regulated, surge-protected outputs addresses the typical pain points of multi-camera installations: centralised cabling, rapid fault identification and resilience against electrical disturbances.
For installers and system owners who need a compact 1U rack unit that prioritises serviceability and reliability, the HAY-RMPSU1612-16A/1U represents a strong choice. Before purchase, verify the product datasheet for environmental and certification details (CE/UKCA or other market-relevant approvals), confirm the intended currency and VAT handling for the suggested RRP, and ensure the per-output and total current figures meet your specific camera or device requirements. Finally, have installation carried out by a qualified electrician or security technician and isolate mains power before servicing to maintain safety and compliance.
