Altronix TM250 Compact Power Supply Enclosure
The Altronix TM250 is a compact power supply enclosure engineered for security infrastructure deployments where space is constrained but modularity is essential. Unlike fixed-output power supplies, the TM250 lets you configure power delivery around your actual system topology—whether that's a single access control door, a multi-zone alarm system, or a distributed video surveillance backend. This enclosure-based design means you're not locked into one power profile; you select and install the specific power modules your installation demands.
Key Features
- Modular Power Architecture: Accepts multiple Altronix power supply modules, so you build the output capacity you need rather than overpaying for unused headroom. Install 12VDC modules, 24VDC modules, or mixed configurations depending on your door strikes, readers, cameras, and auxiliary devices.
- Compact Form Factor: Designed for equipment rooms, closets, and wall-mount locations where rack-mount infrastructure isn't practical. Vertical mounting orientation saves floor space in cramped installations.
- Professional Enclosure Housing: Durable construction rated for indoor environments protects internal components from dust, accidental contact, and minor environmental stress. This means longer component life and fewer field callbacks.
- Simplified Installation and Maintenance: Organized internal layout and accessible terminal blocks reduce wiring time and troubleshooting complexity. Technicians can swap failed modules without tearing apart the entire distribution point.
- Standardized Altronix Module Compatibility: Works with the broader Altronix power supply family, so you're not locked into one vendor's ecosystem if you need to expand or upgrade power distribution downstream.
- Lifetime Limited Warranty: Manufacturer backs the enclosure with a lifetime limited warranty, reflecting confidence in industrial-grade construction and reducing long-term cost of ownership on permanent infrastructure.
Integration & Compatibility
The TM250 integrates into any power infrastructure architecture where modular, space-constrained distribution is the goal. Common scenarios include centralizing power for multi-door access control systems, consolidating backup power feeds for distributed video surveillance nodes, or provisioning redundant power circuits for alarm panel hubs. Because the TM250 accepts standard Altronix power modules, you can future-proof your installation—swap in higher-capacity modules if your system grows without replacing the entire enclosure.
Deployment Considerations
The modular design is a strength, but it also requires planning: you must select the correct modules upfront based on your load calculations. Undersizing modules means inadequate backup power or insufficient peak current for door strikes during high-traffic periods. Oversizing wastes money and generates unnecessary heat. Use accurate power budgets for every connected device—cameras, readers, locks, intercoms—and verify the module selection before ordering. Indoor-only rating means the TM250 is not suitable for external cabinets, vehicle mounts, or harsh outdoor environments; if you need weatherproof distribution, consider a different enclosure class.
The Altronix TM250 is the right choice when you need compact, configurable power distribution without the cost and footprint of a full rack cabinet, and when you're comfortable selecting and installing compatible power modules to match your actual load.
Frequently Asked Questions
Q: Can I mix different voltage modules (12VDC and 24VDC) inside the same TM250 enclosure?
A: Yes. The TM250 is designed to accept multiple independent power modules in various voltage configurations. This flexibility allows you to support mixed-voltage systems—for example, 24VDC for door strikes and locks, 12VDC for readers or auxiliary relays—all from a single enclosure.
Q: What is the maximum power output of the TM250?
A: Output capacity depends entirely on which Altronix power modules you install. The enclosure itself has no fixed maximum; it is determined by the sum of the modules installed. Consult the specific power module datasheets to calculate total available current and power.
Q: Is the TM250 suitable for outdoor cabinet mounting?
A: No. The TM250 is rated for indoor mounting only and does not carry an IP67 or outdoor weather rating. For outdoor or exposed installations, you will need an outdoor-rated enclosure or a different power distribution platform.
Q: Does the TM250 come pre-loaded with power modules?
A: No. The TM250 is an empty enclosure. You must select and purchase the appropriate Altronix power supply modules separately based on your system voltage and current requirements.
Q: How do I mount the TM250?
A: The TM250 is designed for wall mounting in equipment rooms or secure closets. Mounting hardware and instructions are included; installation should be performed by a qualified security technician.

The Altronix TM250 solves a specific problem: you need distributed power for security devices, but you don't want to waste budget on a full rack enclosure or deal with the footprint overhead in a closet or utility room. The modular design of the TM250 is its core strength—you only pay for the output capacity you actually deploy.
Technical Highlights:
- Modular Configuration: Mix and match Altronix power modules to match your exact load. No one-size-fits-all penalty; a two-door system doesn't subsidize 32-door capacity.
- Compact Indoor Footprint: Purpose-built for equipment rooms and wall mounting where space efficiency matters. Vertical orientation is standard, reducing the enclosure's real estate demand.
- Lifetime Limited Warranty: The manufacturer warranty reflects industrial-grade construction—you're not replacing this in five years if it's properly maintained and the environment is controlled.
Deployment Considerations:
- Load calculation is non-negotiable. Undersized modules create nuisance power brownouts during peak card reader or lock activity; oversized modules waste capital and generate unnecessary heat dissipation challenges.
- The TM250 is indoor-only. If your equipment room is adjacent to an outdoor wall or exposed to humidity or temperature swings, plan for environmental conditioning or select an outdoor-rated enclosure class instead.
- Module selection happens at order time. Unlike some larger systems, you don't just plug in a generic 'power supply'—you're configuring individual modules, so coordinate voltage and current ratings carefully with your door control manufacturer's data.
Deploy the TM250 when you're consolidating power distribution for access control, alarm system hub backup, or video NVR/switch clusters in space-constrained indoor locations. It's not the choice for outdoor cabinets or systems that require hot-swap redundancy, but for a permanent equipment room installation where modularity and compact form factor align, the TM250 delivers straightforward, reliable power distribution without overspecification.
