Altronix OLS200220 12VDC 10A Board-Form Power Supply
The Altronix OLS200220 is a board-level power supply and charger designed for stationary installation in security infrastructure cabinets, control panels, and industrial control enclosures. It accepts 220VAC mains input—standard in international deployments—and delivers regulated 12VDC output at up to 10A maximum current. The single consolidated output simplifies wiring and eliminates the need for multiple power conditioning devices in cramped panel spaces.
Key Features
- 220VAC Input Rated: Matches international standard mains power, eliminating the need for voltage conversion hardware in facilities outside North America. This is a genuine advantage if your installation spans multiple countries or operates in regions where 110VAC infrastructure is rare.
- 12VDC Regulated Output at 10A Maximum: Delivers 120W total capacity. For reference, this supports roughly 10–12 standard door strike locks, or a mid-sized access control panel with battery backup, or mixed loads of IP cameras, sensors, and logic devices. The regulated output protects downstream electronics from voltage sag and ripple.
- Integrated Battery Charging Capability: Built-in charging circuitry means you can pair the OLS200220 directly with a 12V backup battery (typically 7–17Ah lead-acid or UPS units) without adding a separate charger module. This is valuable in access control and alarm panels where loss of mains power cannot result in loss of door control or alarm sensing.
- Board-Level Form Factor: Mounts directly to DIN rail or as a plug-in module inside an enclosure. No external casing; no wasted space. This is critical in retrofit scenarios where panel real estate is already tight and cabinet depth is limited.
- Single Output Consolidation: One output connector reduces the wiring footprint and simplifies troubleshooting compared to multi-output supplies where load-balancing and output isolation become concerns.
- Lifetime Limited Warranty: Covers defects in materials and workmanship for the life of the product—meaningful reassurance for infrastructure that may run 10+ years without replacement. Limited warranty typically excludes damage from misuse, overvoltage, or environmental extremes, so read the terms carefully.
When to Consider This Supply
Choose the OLS200220 if your installation is 220VAC-fed (or requires international-standard mains conversion) and you need a compact, direct-mounting power source for access control panels, alarm panels, or security camera backbone power with integrated battery charging. If your facility runs on 110VAC North American mains, you will need a different model. If you require higher current capacity—say, 15A or 20A for a large panel with many loads—consider a higher-output variant in the Altronix power supply line.
Integration & Compatibility
The OLS200220 is supply-agnostic: it outputs standard regulated 12VDC and is compatible with any 12V load that draws ≤10A aggregate current. Common integration points include access control readers, strike mechanisms, status LEDs, solenoid locks, and IP camera PoE injectors that accept 12V input. Verify that your specific panels and accessory devices support 12VDC operation; some legacy systems expect 24VDC, which the OLS200220 does not provide.
Frequently Asked Questions
Q: Is the OLS200220 suitable for outdoor installation?
A: No. This is a board-form supply designed for stationary indoor installation inside cabinets, panels, or control enclosures. It has no environmental rating (IP rating) and is not sealed against moisture or UV exposure. Install it inside a weatherproof cabinet if the cabinet itself will be outdoors.
Q: Can I parallel multiple OLS200220 units to increase current capacity?
A: Paralleling unregulated or independently regulated supplies is not recommended without external load-sharing circuitry, as output voltage mismatch between units can cause one supply to source significantly more current than the other, leading to premature failure. Consult the manufacturer or upgrade to a single higher-capacity supply instead.
Q: What battery capacity should I use with the OLS200220 for backup power?
A: The integrated charger is designed for lead-acid or sealed lead-acid (SLA) batteries in the 7–17Ah range at 12V. The exact runtime depends on your total load current and battery Ah rating; a 10A load on a 7Ah battery provides roughly 42 minutes of runtime before voltage sag. Calculate your critical-load current and multiply by your target runtime (in hours) to size the battery.
Q: Does the OLS200220 have short-circuit protection?
A: Standard practice for Altronix supplies includes current limiting or foldback protection to prevent catastrophic failure in a short-circuit event, but consult the datasheet or technical documentation for specific protection topology. Do not assume unlimited short-circuit tolerance.
Q: What is the input voltage tolerance for 220VAC operation?
A: Typical industrial 12V power supplies accept input in the range 176–264VAC (±10% nominal 220V). Verify in the technical documentation whether the OLS200220 is rated for your local mains variation. Extreme brownout or overvoltage conditions outside this range may compromise output regulation or trigger protection circuits.

The Altronix OLS200220 is a straightforward, field-proven choice for stationary security and access control installations that run on 220VAC mains and require integrated battery charging in a compact footprint. The 10A capacity at 12VDC is sufficient for most mid-sized access control panels, alarm processors, and camera backbone power—a real advantage over trying to cobble together multiple smaller supplies or retrofitting external battery chargers into an already-crowded cabinet.
Technical Highlights:
- 220VAC Input, Regulated 12VDC @ 10A Output: Delivers 120W of usable power with voltage regulation that keeps downstream 12V devices happy even when mains sag slightly. Not enough? You'll need a higher-capacity supply; this one tops out at 10A, so load planning is non-negotiable.
- Integrated Battery Charging: The built-in charger circuit accepts 7–17Ah sealed lead-acid batteries without external charge controllers. This cuts down on panel clutter and reduces the risk of overcharging a backup battery left unattended for months.
- Board-Form Mounting: DIN rail or direct enclosure mount saves space compared to wall-mounted supplies with long cable runs. In retrofit work, this is often the difference between fitting inside the existing cabinet or requiring a larger enclosure.
Deployment Considerations:
- 220VAC mains only—if your facility is 110VAC North American standard, this is a non-starter and you need a different model from the Altronix catalog.
- No environmental protection—board-level supplies are designed for climate-controlled panel spaces. If moisture, dust, or temperature extremes are in play, the enclosure itself must provide protection, not the supply.
- Battery sizing is critical. Many installers underestimate backup runtime by choosing undersized batteries; calculate your actual critical-load current and multiply by your required runtime (typically 8–24 hours for access control). A 7Ah battery with a 10A total load gives you roughly 40 minutes—often insufficient for multiday power outages.
The OLS200220 shines in established international deployments or retrofit projects where 220VAC is already present and you need to consolidate power and backup charging into one compact module. Don't force it into a 110VAC facility, and don't skimp on battery capacity when lives or property security depend on door control staying live.
