Altronix OLS120D2X Dual-Output Power Supply/Charger
The Altronix OLS120D2X is an enclosure-based power supply and battery charger engineered for access control systems, networked security infrastructure, and multi-device power distribution in enterprise deployments. This unit accepts both 115VAC and 230VAC input — eliminating the need for separate SKUs across different regions — and delivers regulated 12/24VDC output across two independent channels. Each output is rated for 4A maximum current, allowing simultaneous powering of two access control panels, door locks, or auxiliary security devices without exceeding a single power budget line.
Key Features
- Dual-voltage input (115/230VAC): Accept either line voltage without reconfiguration or multiple SKU inventory. Simplifies deployment across North American, European, and mixed-region facilities.
- Two independent 12/24VDC outputs at 4A each: Power two separate security loads simultaneously — for example, an access control panel on one channel and a battery charger on the second — without starving either device due to shared current limits.
- Selectable output voltage (12VDC or 24VDC per channel): Configure each channel independently to match the voltage requirement of its connected device. No need for multiple PSU models to cover 12V and 24V gear in the same system.
- Integrated battery charger: Trickle-charge backup batteries within the same enclosure, reducing external hardware clutter and simplifying wiring in access control racks and server closets.
- Enclosure form factor: Wall- or rack-mountable steel housing protects components and simplifies integration into secure equipment rooms; weatherproof design supports both indoor and moderately harsh environments.
- Lifetime Limited Warranty: Covers component and manufacturing defects indefinitely, reducing long-term replacement costs in mission-critical access control systems.
When to Choose the OLS120D2X
Select this model if you are deploying dual-powered access control panels, redundant door readers, or any scenario where two independent 4A power feeds must coexist in a single enclosure. The 4A per-channel rating is sufficient for most standard access control panels and single door lock circuits, but if you require 8A on a single channel or higher aggregate power, consider stepping up within the Altronix power supply lineup.
The ability to configure each output independently (12V or 24V) avoids the need to stock multiple SKUs when your facility uses mixed-voltage equipment. The integrated charger is a genuine operational advantage in access control racks where battery backup must be continuously maintained without adding external charger hardware.
Integration & Compatibility
The OLS120D2X is designed as a standalone power and charging source for access control panels, door readers, and power distribution in security systems. Verify that each connected load does not exceed 4A at its selected voltage (12V or 24V). If integrating into a networked video recording infrastructure, confirm that the power budget for any PoE switches or auxiliary equipment can be drawn from the second channel without exceeding the 4A limit.
Deployment Scenario
A typical deployment might include an access control panel drawing 3A at 24VDC on Channel 1, with Channel 2 configured to 24VDC and delivering 4A to a battery charger for backup power. The enclosure mounts in a locked electrical room or cabinet, fed from a standard 115VAC wall circuit. Both channels operate independently, so a fault or overload on one does not affect the other.
Frequently Asked Questions
Q: Can both outputs deliver 4A simultaneously?
A: Yes. Each of the two channels is independently rated for 4A maximum at its selected voltage (12V or 24V). Both can operate at full rating at the same time without derating the other channel.
Q: What is the warranty on the OLS120D2X?
A: Lifetime Limited Warranty covers manufacturing defects and component failure for the life of the unit.
Q: Does the OLS120D2X accept 230VAC input directly?
A: Yes. The unit accepts both 115VAC and 230VAC input without configuration. This eliminates the need for separate models in different regions.
Q: Can I configure one output to 12VDC and the other to 24VDC?
A: Yes. Each channel is independently selectable for 12VDC or 24VDC output, allowing you to power equipment with different voltage requirements from a single enclosure.
Q: Is the OLS120D2X suitable for outdoor mounting?
A: The enclosure form factor provides protection, but verify that the specific mounting location and environmental conditions align with the unit's operating temperature and humidity ranges. Consult the datasheet for exact environmental limits.
Q: What battery types can the integrated charger support?
A: The charger is designed for sealed lead-acid backup batteries commonly used in access control systems. Refer to the datasheet for specific battery chemistry compatibility and recommended ampere-hour ratings.

The Altronix OLS120D2X hits a specific niche: sites running dual access control infrastructure — think a large facility with separate zones or a campus with separate buildings, each requiring independent power and battery backup. The 4A per-channel rating is the defining spec here; it's enough for a standard door controller and a couple of readers, but not overkill for simpler systems. If your deployment is straightforward — one panel, one charger — this model works. If you're trying to cram eight readers or three panels into one supply, you'll hit the ceiling.
Technical Highlights:
- Dual-voltage input (115/230VAC): Eliminates regional SKU fragmentation. Ship the same hardware to North America, Europe, or Asia-Pacific without rewiring or reconfiguration.
- Independent channel selection (12V or 24V per output): Avoids the inventory tax of stocking separate 12V and 24V supplies. One SKU covers multiple voltage scenarios in mixed-equipment deployments.
- 4A per channel at full load: Adequate for access panels and single-circuit door lock loads, but tight if you're powering multiple heavy-draw devices. Plan load distribution carefully — a second Altronix OLS120D2X in tandem may be necessary for high-complexity sites.
Deployment Considerations:
- The 4A per-channel limit is a hard ceiling. Verify total steady-state and surge current for every connected load before deployment. A miscalculated load can cause the supply to fold back and trigger false alarms.
- The integrated charger is a convenience, but it's not a substitute for proper UPS or backup power planning. Use this for trickle-charging batteries between power events, not as the primary battery charging strategy for high-availability systems.
- Enclosure mounting is straightforward, but ensure adequate ventilation — power supplies generate heat under sustained load. Poor airflow in a locked cabinet can degrade component lifespan.
Best fit: mid-sized access control deployments with two independent power circuits and moderate current draw per circuit — a secondary building entrance, a warehouse zone, or a multi-tenant floor. Skip this if you need more than 4A per channel or if you're running a primary data center power tree; step up to a larger Altronix supply or a dedicated industrial UPS instead.
