Introduction to the RGL 1202SM-1 and its key features
RGL 1202SM-1 — Compact 13.8 VDC / 2 A switch‑mode power supply with battery backup.Designed specifically for CCTV, access control and intruder alarm systems, the RGL 1202SM-1 combines a regulated 13.8 VDC output with on‑board battery charging, built into a tamper‑protected steel enclosure. Its switch‑mode topology delivers efficient power conversion with lower heat output and a smaller footprint compared with traditional transformer‑based supplies. Key features include a continuous 2 A output, support for a single 12 V sealed lead‑acid battery up to 9 Ah, front‑panel LEDs for status, fused mains input, a tamper switch and multiple cable entry points.
- Regulated 13.8 VDC output:Keeps connected cameras and access devices running within the correct voltage range, reducing false triggers and extending device life.
- Switch‑mode topology:Higher efficiency and less heat generation mean more reliable operation in confined enclosures and reduced operating costs.
- On‑board battery charging and protection:Ensures smooth transition to backup power during outages and protects the battery from deep discharge, prolonging service life.
- Compact, tamper‑proof enclosure:Keeps the electronics secure and neat, suitable for wall or cabinet mounting where security and professional presentation matter.
Detailed specifications and benefits
The RGL 1202SM-1 is built around a practical specification set tailored for small to medium CCTV and access control installations. Below is a breakdown of the main specification areas and the real‑world benefits each provides.
- Output Voltage:13.8 V DC (regulated). This slightly higher-than-12 V nominal setting compensates for voltage drops in cabling and helps ensure connected devices receive adequate voltage under load.
- Output Current:2 A continuous. Suitable for small systems or a handful of cameras and peripheral devices; provides steady supply without overheating under normal loads.
- Mains Input:Fused mains input for safety. (Refer to manufacturer/distributor for detailed mains input ratings.)
- Battery Supported:Single 12 V sealed lead‑acid battery up to 9 Ah. This provides meaningful runtime for small systems, typically allowing cameras and essential sensors to operate through short outages.
- Battery Charging:On‑board charger with deep‑discharge protection. The charger maintains a healthy battery state and prevents deep discharge that can permanently damage SLA batteries.
- Protections:Deep‑discharge protection, current limiting, short‑circuit protection and mains transient protection. These protections safeguard both the power supply and connected devices from common faults.
- Indicators:Front LEDs for mains, battery and output status. Quick visual checks make troubleshooting and commissioning faster for installers.
- Enclosure:Mild‑steel, white powder‑coated with tamper switch and multiple cable entry points (including rear). Durable, discreet and secure for professional installations.
- Dimensions & weight:225 x 196 x 75 mm; approx. 1.46 kg boxed. Compact enough to fit into small equipment cabinets or shallow wall enclosures.
- EMC:Compliant to EN61000‑6‑1 & EN61000‑6‑3, reducing the risk of electromagnetic interference with nearby equipment.
- Installation guidance:Install in accordance with local electrical regulations. Isolation of mains supply before servicing is required and battery connections must be checked to avoid damage.
Use cases and scenarios where the RGL 1202SM-1 excels
The RGL 1202SM-1 is aimed predominantly at small-scale CCTV and access control deployments where reliable, enclosed power with backup is required. Typical scenarios include:
- Small commercial premises:Boutique shops, offices, and small retail outlets that need a compact power source for a few cameras and an access panel without the expense or size of larger power systems.
- Residential systems:Home CCTV or alarm systems where a secure, wall‑mounted power supply with battery backup keeps critical sensors and cameras online during short outages.
- Access control panels:Single-door or small multi-door access setups requiring constant DC power and a short-term backup to ensure locks and controllers remain operational.
- Remote or satellite sites:Locations such as small kiosks, storage units or remote equipment cabinets where space and ventilation are limited but battery backup is still necessary.
- Contractor & DIY installations:The unit is straightforward for experienced DIYers and professional installers familiar with low‑voltage DC systems to mount, wire and commission quickly.
How it compares with similar products on the market
When choosing a CCTV power supply, installers typically weigh factors such as reliability, size, backup capability, protection features and price. Here’s how the RGL 1202SM-1 stacks up against common alternatives:
The RGL 1202SM-1 uses switch‑mode technology, which tends to be smaller, lighter and more efficient than transformer/linear equivalents. That translates to lower heat, improved longevity and easier mounting in compact enclosures. Transformer-based boxed supplies can be bulkier and run hotter, but sometimes offer simpler designs for very low-cost systems.
Some power options require separate battery enclosures or external chargers. The RGL’s integrated battery charging and deep‑discharge protection simplifies installation and reduces the number of separate components to manage. For larger systems needing longer runtimes, rack-mounted multi‑channel supplies or higher current models (5 A, 10 A) with larger battery banks will be more appropriate.
At a suggested price around $44.95, the RGL 1202SM-1 targets the budget-conscious installer who still needs key protections and a secure enclosure. Competing units at similar price points may omit deep‑discharge protection, include fewer status indicators or offer lower rated batteries, so the RGL represents a balanced feature set for its class.
Customer feedback and representative reviews
Actual customer reviews for specific SKUs vary by retailer. Below are representative comments based on feedback typically reported by installers and end users for compact switch‑mode boxed supplies with battery backup:
- "Reliable little unit — easy to mount, LEDs help troubleshooting and the battery charging has been rock solid in outages." — Installer feedback pattern
- "Perfect for a small retail CCTV setup. Small footprint and gives us a few hours of uptime with a 7 Ah battery." — Typical end user comment
- "Good value for money. Would like clearer mains spec labelling on the casing but otherwise fine for DIY installs." — Common installation note
These representative points reflect the sort of practical praise and constructive observations you can expect: solid performance, compactness and value, with minor suggestions around documentation or labelling that are common across lower-cost, feature‑rich units.
Conclusion: Why choose the RGL 1202SM-1?
The RGL 1202SM-1 13.8V 2A switch‑mode power supply with battery backup presents a pragmatic solution for small CCTV, access control and alarm applications. Its regulated 13.8 VDC output, efficient SMPS design, onboard battery charging with deep‑discharge protection and tamper‑proof steel enclosure deliver the essentials that installers and end users need: dependable power, tidy installation and short‑term backup capability. At a competitive suggested price, it offers an attractive balance of performance and affordability for projects that don’t require larger, higher‑current power systems.
Before purchase, verify that the 2 A output and maximum supported battery capacity (12 V up to 9 Ah) meet your runtime requirements, and ensure installation follows local electrical codes. For small sites and straightforward installations, the RGL 1202SM-1 is a compact, cost‑effective choice that keeps cameras, access controllers and alarms running reliably, even when mains power is interrupted.
