Introduction to the CDVI PSMB125 and its key features
CDVI PSMB125 (Ref: F0301000016)is a compact, lockable switch‑mode power supply designed specifically for access control and security installations. Housed in a white metal enclosure with a secure lock, this unit provides a regulated 12 V DC output with up to 5 A continuous current and includes an internal charger for a single 12 V, 7 Ah backup battery (battery sold separately). With universal mains input (190–265 V AC), built‑in protections and clear LED status indicators, the PSMB125 is built to deliver reliable power and a tidy, secure installation for maglocks, card readers and access control panels.
Detailed specifications and benefits
The PSMB125 is engineered around a set of practical specifications that matter to installers and facility managers. Below is a concise breakdown of the technical specs and the benefits they deliver in real installations.
- Output voltage:12 V DC nominal (charges the battery at approximately 13.8 V). Benefit: Provides the correct operating voltage for most access control devices while maintaining an appropriate float/charge voltage for lead‑acid backup batteries.
- Output current:5 A continuous. Benefit: Supports a typical combination of door locks, readers and control panels on small to medium installations without requiring an external PSU cluster.
- Mains input:190–265 V AC (universal). Benefit: Simplifies deployment across regions and buildings with varying supply standards; reduces inventory needs for different line voltages.
- Battery charger:Internal charger for one 12 V, 7 Ah SLA battery (battery not included). Benefit: Backup power is integrated, keeping devices operational during mains loss and minimizing cabinet clutter.
- Protections:Short‑circuit, thermal protection and battery charge control. Benefit: Enhances long‑term reliability and protects connected devices and the PSU from common fault conditions.
- Enclosure:Lockable metal box, surface mount. Benefit: Keeps cabling and batteries secure from tampering while supporting neat, professional installations.
- Dimensions:265 × 195 × 75 mm. Benefit: Compact footprint that fits in many IT and electrical cupboards or behind access control panels.
- Weight:Approximately 0.94–1.24 kg. Benefit: Lightweight construction eases mounting and handling on site.
- IP rating:IP20 (indoor use). Benefit: Suitable for protected indoor environments such as plant rooms, cupboards, or inside receivers and cabinets.
- Indicators:LEDs for mains, battery/charge and fault. Benefit: Quick visual checks for power and charging status help maintenance teams diagnose issues without tools.
- Installation:Requires installation by a qualified electrician or installer; follow local wiring regulations and the CDVI installation manual. Benefit: Ensures safe, compliant wiring and correct battery hookup for longevity and safety.
- Warranty:CDVI advertises a long manufacturer family warranty (10 years referenced by distributors). Benefit: Long warranty periods offer peace of mind and reflect manufacturer confidence in product longevity.
Use cases and scenarios where the PSMB125 excels
The PSMB125 is aimed at scenarios where a compact, secure power source with backup capability is needed. Typical use cases include:
- Powering a single maglock or an electric strike along with one or two readers and a control panel. The 5 A continuous output is well suited to systems where devices are not all drawing peak current simultaneously.
- For small offices, retail outlets or industrial units with a handful of controlled doors, the PSMB125 provides the regulated power and battery backup required for continued operation during mains interruptions.
- Used as a neat, lockable power source inside security cabinets or plant rooms where a sealed battery is kept on standby; LEDs enable rapid checks by maintenance staff.
- Its compact enclosure and universal mains input make the PSMB125 a good option for retrofits where space is limited and power requirements are modest.
Comparisons with similar products on the market
There are several categories of comparable products: basic unprotected PSUs, PSUs with external battery connections, and integrated lockable PSUs with chargers like the PSMB125. When evaluating the PSMB125 against alternatives, consider the following points:
Some power supplies provide only a DC output and require a separate charger or external battery enclosure. The PSMB125’s integrated charger simplifies installation and reduces the number of components that need mounting and wiring. For installers who want a single cabinet with tidy wiring and a dedicated battery bay, the PSMB125 is advantageous.
Lockable metal enclosures protect batteries and wiring from tampering and accidental contact. Cheaper PSUs in open metal frames or plastic enclosures may save initial cost but can be less secure and less professional in appearance. For installations that require physical security or visible professionalism—such as retail or corporate sites—the PSMB125’s lockable box is a clear benefit.
Basic PSUs may omit thermal protection, automatic battery charge control or clear status LEDs. The PSMB125 includes short‑circuit and thermal protection plus LEDs for mains, charge and fault — features that reduce troubleshooting time and help protect connected devices.
At a suggested price point that reflects an integrated charger and lockable enclosure, the PSMB125 competes strongly when warranty and long‑term reliability are factored in. CDVI’s advertised 10‑year family warranty (as referenced by distributors) positions it well against alternatives with shorter manufacturer support periods.
Customer feedback and installer impressions
While individual project results vary, installers commonly highlight a few themes when discussing lockable, charger‑equipped PSUs like the PSMB125:
- Ease of installation: Integrated charger and universal mains input reduce the number of components to wire and configure, saving time on site.
- Neat, secure presentation: The lockable metal box keeps batteries and wiring protected and gives a professional finish to installations in visible areas.
- Serviceability: LED indicators for mains and battery status simplify fault finding and routine checks.
Because user reviews for a specific model can depend on the distributor and local installers, prospective buyers should consult local references or ask installers for examples of recent deployments of the PSMB125 to confirm fit for purpose.
Conclusion: Why the CDVI PSMB125 is a strong choice
The CDVI PSMB125 (F0301000016) is a practical, well‑rounded power solution for access control and small security systems. Its combination of a regulated 12 V DC output, 5 A continuous current, internal charger for a 12 V/7 Ah battery, secure lockable metal enclosure and essential protections make it an efficient choice for installers who want a tidy, reliable power source with built‑in backup capability.
Key selling points are its streamlined installation, clear status indicators, robust protection features and the long manufacturer family warranty that underlines CDVI’s confidence in the product.
