Altronix VR6 24VDC to 5VDC/12VDC Voltage Regulator
The Altronix VR6 is a compact voltage regulator designed to convert incoming 24VDC power to either 5VDC or 12VDC output, delivering a continuous 2A at the selected voltage. This single device eliminates the need to stock and deploy multiple power supplies when your security infrastructure includes mixed-voltage components—a common scenario in access control, fire safety, and sensor networks where auxiliary devices run on different voltages than your primary distribution.
Key Features
- Selectable Output Voltage (5VDC or 12VDC): Configure the VR6 for your target voltage once, then standardize on a single supply topology across multiple installations. No need to maintain separate 5V and 12V power supplies in your truck or warehouse.
- 2A Continuous Output Current: Sufficient to power a small cluster of low-draw sensors, detectors, or auxiliary control modules. Calculate your load carefully—exceeding 2A will trigger current-limiting protection and degrade performance.
- PoE-Compatible Power Sourcing: The VR6 accepts 24VDC input from standard enterprise PoE infrastructure (via midspan injectors or PoE switches), reducing panel-mounted power supply count. This works particularly well in distributed security systems where 24VDC is already routed to remote devices.
- Fire Alarm Disconnect: Built-in disconnect capability integrates with fire/life-safety protocols, allowing the regulator to be isolated during emergency shutdown sequences without requiring external relay logic.
- Compact Form Factor: Designed for DIN-rail mounting or integration into existing power distribution panels. Minimal footprint keeps panel layouts clean and simplifies commissioning.
- CE Marking & Regulatory Compliance: Meets European Union directives for safety and electromagnetic compatibility. Verify local electrical codes before deployment—some jurisdictions require additional certification or inspection for life-safety circuits.
- Lifetime Limited Warranty: Manufacturer-backed coverage protects against material and workmanship defects. Review warranty terms for exclusions related to overvoltage, reverse polarity, or load-induced failure.
Integration & Compatibility
The VR6 functions as a straightforward DC-to-DC converter and integrates into any 24VDC infrastructure. Input requires 24VDC (±10% tolerance is typical—confirm in the datasheet); output is selectable at the device. No external configuration, firmware, or software is required. Pair the VR6 with your existing power infrastructure strategy—it reduces the number of discrete supply models you need to support, which lowers spare-parts inventory and training overhead.
Common deployment patterns: powering remote access-control readers over extended runs where voltage drop is a concern, supplying auxiliary sensors in a fire-alarm loop, or distributing low-voltage DC to modular expansion cards in a security control panel. The voltage regulator category includes other options if you need higher output current (4A, 6A), multiple outputs, or integrated monitoring features.
When to Choose a Different Model
If your load exceeds 2A continuous, consider a higher-capacity regulator in the Altronix power family. If you require dual-output channels (e.g., simultaneous 5VDC and 12VDC) or integrated current metering, look for a multi-output or supervised variant. For fire-alarm-specific installations, verify that your AHJ (authority having jurisdiction) accepts the VR6's disconnect method; some localities mandate additional isolation relays or monitoring circuitry.
Typical Wiring & Commissioning Notes
Input and output are clearly marked on the device. Polarity is critical—reverse-polarity connection will damage the regulator. Confirm 24VDC source voltage (measure with a multimeter before wiring) and set the output selector jumper or switch to your target voltage (5V or 12V) before applying power. Allow a few seconds for output to stabilize; some loads may require a small filter capacitor on the output if they are sensitive to transients.
Frequently Asked Questions
Q: Can I use the VR6 with a standard 24VDC power supply, or does it require PoE?
A: The VR6 accepts any regulated 24VDC source—PoE injectors, traditional 24V supplies, or battery backup systems. PoE compatibility means it can accept 24VDC delivered over Ethernet cabling via a PoE injector or PoE switch, simplifying remote installations.
Q: What happens if I exceed the 2A current limit?
A: The VR6 includes current-limiting protection. When load current exceeds 2A, the output voltage will drop and the regulator will throttle power to prevent thermal damage. This is not a graceful shutdown—your downstream devices will experience brown-out conditions. Size your load to stay below 2A continuous.
Q: Is the output voltage selectable in the field, or is it factory-set?
A: The VR6 is selectable via an on-board jumper or switch. You can change the output voltage (5VDC or 12VDC) without ordering a different model, but you must power down the device before toggling the selector.
Q: Does the VR6 have any monitoring or status outputs?
A: The VR6 is a passive voltage regulator with no built-in monitoring, relay contacts, or alarm outputs. If you need supervised power distribution (e.g., alerts on loss of output voltage), consider a supervised regulator or add external monitoring circuitry.
Q: Is the VR6 suitable for fire-alarm circuits?
A: The VR6 includes fire-alarm disconnect capability, making it suitable for auxiliary power to fire-safety devices. However, verify with your local AHJ and system integrator that the disconnect method meets your jurisdiction's life-safety requirements before deployment.
Q: What is the input voltage tolerance for the VR6?
A: Standard industrial practice is ±10% around the nominal 24VDC (typically 21.6V to 26.4V). Confirm the exact range in the manufacturer datasheet before specifying your 24VDC source.

The Altronix VR6 is a no-nonsense voltage regulator that solves a real logistics problem: consolidating power supplies in mixed-voltage security installations. The selectable 5VDC or 12VDC output means you carry one model instead of two, and the PoE input option lets you leverage existing 24VDC infrastructure—especially valuable in distributed access-control and fire-alarm deployments where you're already routing 24V over long cable runs.
Technical Highlights:
- 2A Continuous Output Current: Adequate for small sensor clusters and auxiliary devices, but tight if you're powering multiple readers or high-draw modules. Load planning is non-negotiable—current-limiting kicks in hard above 2A.
- Selectable Output (5V or 12V): Field-configurable via jumper eliminates separate SKU overhead. One part number, two common voltages—clean procurement and inventory strategy for multi-project integrators.
- Fire Alarm Disconnect: Built-in isolation meets life-safety circuit requirements in many jurisdictions, but you must still verify AHJ acceptance. Don't assume it passes every local code without explicit approval.
Deployment Considerations:
- Measure your actual load current before sizing the VR6—2A is the hard limit. Undersizing here will cause voltage sag and erratic device behavior downstream.
- Input voltage tolerance matters: confirm your 24VDC source is stable within ±10%. Noisy or sagging inputs will degrade output regulation and stress connected equipment.
- The VR6 has no status outputs or monitoring. If you need alerts on power loss (common in fire-safety), you'll add external circuitry or choose a supervised variant.
Best fit: access-control reader clusters and sensor loops in fixed installations where load is predictable and 24VDC is already present. Less suitable for high-reliability fire-alarm primary circuits—those often demand redundancy and supervised metering that a simple pass-through regulator cannot provide.
