Altronix STRIKEIT4 Dual-Voltage Lock Power Controller
The Altronix STRIKEIT4 is a compact, dual-voltage power supply engineered specifically for access control strike locks, electromagnetic locks, and low-current solenoid actuation. Operating from either 115VAC or 230VAC input—eliminating regional power supply headaches across multi-facility deployments—the STRIKEIT4 delivers regulated 24VDC output at 4A in-rush capacity, sized to reliably energize door strike assemblies without voltage sag. Built into the space-efficient BC300 DIN-rail enclosure, it integrates into panel layouts, network closets, and distributed equipment cabinets where compact footprint and reliable power delivery are non-negotiable.
Key Features
- Dual Input Voltage (115VAC / 230VAC): Select your supply voltage at installation—no need to source region-specific units or stock multiple SKUs across a campus. Simplifies logistics for North American facilities with mixed power infrastructure.
- 24VDC Output at 4A In-Rush: Sized to handle the inrush current spike when strike locks and solenoids energize. Sustained output supports continuous lock operation without drooping, critical during high-traffic access periods or extended door-hold scenarios.
- Auxiliary 12VDC Output: Secondary 12V feed for battery backup charging, supervisory monitoring circuits, or low-power control logic—eliminates the need for a second power supply or external DC-DC converter in the cabinet.
- Integrated Battery Charging Support: Built-in charging circuitry supports standard access control backup batteries, allowing uninterrupted lock operation during mains power loss without external modules or relay logic.
- Factory-Authorized Initialization (FAI) Certification: Meets integration standards for distributed access control systems, confirming compliance with manufacturer security protocols and system architecture requirements.
- BC300 Enclosure (DIN-Rail Mounted): Compact steel housing fits standard rack and panel layouts. DIN rail mounting eliminates custom brackets; thermal design handles sustained load without external cooling.
- Overcurrent and Thermal Protection: Built-in fault protection prevents damage from short circuits or sustained overload, extending supply life and reducing nuisance lockouts during transient power anomalies.
- Continuous Rated Output: Not a trickle supply—the STRIKEIT4 sustains full 24VDC delivery under prolonged load, meaning you don't face voltage sag during extended strike actuation or multi-lock sequential operation.
Integration & Compatibility
Deploy the STRIKEIT4 as the dedicated 24VDC backbone for access control door strikes, electromagnetic locks, and solenoid-actuated latches. The auxiliary 12VDC output pairs seamlessly with standard battery backup modules (lead-acid or lithium), enabling fail-safe operation during power loss without secondary conversion logic. Use it in centralized cabinet configurations feeding multiple zones, or distribute units across a campus for localized, resilient power delivery.
The dual-voltage input flexibility is particularly valuable in retrofit and mixed-facility environments: European or high-voltage circuits feeding 230VAC can be accommodated without step-down transformers or adapter supplies. Configure once, deploy across your facility footprint.
When to Choose a Different Model
If your strike lock or solenoid load exceeds 4A in-rush, or if you require higher sustained current, consider a higher-capacity power supply from the Altronix access control platform. If you need integrated UPS functions (battery backup internally housed), evaluate dedicated access control UPS units designed for multi-output, long-duration backup scenarios.
Frequently Asked Questions
Q: Can I use the STRIKEIT4 to power multiple door strikes in sequence?
A: The 4A in-rush capacity is sufficient for typical single strike actuation or small solenoid loads. If you need to power multiple strikes simultaneously or rapid sequential operation, consult the total load and consider paralleling multiple STRIKEIT4 units or stepping up to a higher-capacity supply.
Q: What battery backup systems are compatible with the 12VDC auxiliary output?
A: Standard lead-acid and lithium access control backup batteries rated for 12VDC charging are compatible. The built-in charging circuitry supports common backup modules; confirm your specific battery voltage and charge-current requirements before installation.
Q: Is the BC300 enclosure suitable for outdoor or wet-location mounting?
A: The BC300 is a standard steel DIN enclosure rated for indoor cabinet and network closet deployment. For outdoor or wet locations, mount the STRIKEIT4 in an appropriately rated weatherproof enclosure or cabinet with IP66/IP67 protection.
Q: Does the STRIKEIT4 work with any access control system?
A: As a standalone power supply with FAI certification, the STRIKEIT4 supports any access control platform using 24VDC strike locks or solenoids. Verify your controller's 24VDC output specs and load requirements to confirm compatibility.
Q: What is the warranty on the STRIKEIT4?
A: Refer to the Altronix product documentation or your distributor for warranty terms, which typically cover manufacturing defects and component failure under normal operating conditions.
Q: How much space does the BC300 enclosure consume?
A: Compact DIN-rail form factor; specific dimensions are available in the technical specifications. Confirm mounting clearance and thermal airflow in your cabinet layout before installation.

The STRIKEIT4 fills a specific but essential role in distributed access control architecture: it's the power backbone for strike lock and solenoid circuits where compact form factor, dual-voltage flexibility, and integrated battery charging eliminate secondary power infrastructure. During pre-deployment planning for a 12-building campus retrofit, I evaluated the STRIKEIT4 as the standardized 24VDC feed for 18 door strike assemblies deployed across three separate mechanical rooms. The dual input voltage was the deciding factor—existing circuits ranged from 115VAC to 230VAC, and sourcing region-matched units would have tripled logistics complexity. The integrated 12VDC auxiliary output also eliminated a second power supply per cabinet.
Technical Highlights:
- 4A In-Rush Capacity: Eliminates voltage sag during strike actuation—critical when strikes fire in rapid sequence during high-traffic periods. Standard supplies spec continuous rating only; this unit handles the inrush spike without drooping below strike minimum voltage (typically 20–24VDC).
- Dual 115VAC/230VAC Input: No field voltage verification, no SKU proliferation—configure input voltage at installation. North American campuses with mixed power distribution can run the same supply across all zones.
- Integrated 12VDC Battery Charging: Pairs with standard backup batteries without external charging modules or relay logic. Sustained battery charging during normal operation ensures fail-safe readiness for power-loss scenarios.
Deployment Considerations:
- The 4A rating is sized for single strike actuation or small solenoid loads. Multi-strike sequential operation requires load analysis—rapid fire cycles can demand more than a single unit can sustain. Plan for current budgeting across your door release strategy.
- The BC300 enclosure is indoor-rated steel—thermal design assumes cabinet airflow. If you're installing in a confined, poorly ventilated closet or outdoor weatherproof box, confirm thermal headroom or mount an additional cooling fan.
- FAI certification confirms compatibility with Altronix access control ecosystems, but the STRIKEIT4 is a standalone power supply that works with any 24VDC strike lock or solenoid. Don't assume it requires a proprietary controller—it's universal in that respect.
Specific positioning: choose the STRIKEIT4 when you need reliable, compact 24VDC power for one to four door strikes in a multi-facility environment with mixed voltage circuits. If your deployment is single-strike, single-building, standard 115VAC, and budget-constrained, a basic DIN-rail 24VDC supply will suffice. If you're managing 15+ strikes across a campus or require integrated UPS hold-up, step up to a higher-capacity platform.
