Power Supplies

Access control power supplies deliver regulated DC voltage and battery charging for electromagnetic locks, strikes, and keypads. Our collection includes Securitron, Security Door Controls, and DETEX models with field-selectable 12V/24VDC outputs from 1A to 10A.

Regulated DC Power Controllers for Magnetic Lock Applications

Your access control infrastructure depends on consistent voltage regulation and intelligent battery management. These aren't basic transformers—they're specialized units engineered for magnetic locks, electric strikes, and door control panels while maintaining fire alarm integration capabilities.

Output Configurations for Single and Multi-Door Installations

Power distribution varies dramatically based on installation scope. Our lineup addresses everything from individual door applications to comprehensive multi-zone networks:

  • 1A–2A boards: Handle single mag lock or strike applications with basic charging circuits
  • 3A–6A multi-output units: Support multiple doors through individually supervised channels
  • 6A–10A network-enabled models: Include monitoring capabilities and auxiliary relay contacts

These supplies are purpose-built for powering high-holding-force magnetic locks, ensuring the coils receive clean, regulated DC even during boost-charge cycles.

Fire Alarm Interface and Emergency Release Functions

Building codes mandate specific emergency egress requirements. DETEX fire-rated enclosures and Securitron AQL series incorporate dedicated fire alarm interface terminals that automatically disengage electromagnetic locks during alarm conditions. Lock-down timers and bypass circuits maintain code compliance across various jurisdictions.

For perimeter security, the same boards can drive motorized gate locks when paired with weather-rated enclosures and battery back-up.

Field-Selectable Voltage with Intelligent Battery Management

Installation flexibility starts with adaptable voltage options. These controllers feature field-selectable 12V/24VDC operation paired with automatic sealed lead-acid battery charging. AC fail monitoring, boost-charge cycles, and low-battery alerts protect your backup power investment while maintaining door security during outages.

If your project calls for specialty devices such as cabinet latches or delayed-egress bars, browse our lineup of miscellaneous electronic locks that tie into these PTC-fused outputs just as easily.

Compact Enclosures with Professional-Grade Components

Space efficiency doesn't compromise functionality in these steel housings. Distribution boards include PTC-fused outputs, LED status indicators per channel, and dry contact reporting for building management integration. UL 294 listings and CSA certifications validate performance standards across commercial applications.

From basic strike control to sophisticated networked installations with auxiliary functions, these power supply solutions provide the electrical foundation your security hardware requires.

Frequently Asked Questions

What amperage do I need for my magnetic lock installation?

Single mag locks typically require 1A–2A, while multi-door installations need 3A–6A. Calculate total lock draw plus 20% safety margin for proper sizing.

Can these power supplies work with both 12V and 24V devices?

Yes, most models feature field-selectable 12V/24VDC output. Simply adjust internal jumpers or switches based on your device voltage requirements.

Do access control power supplies include fire alarm integration?

Securitron AQL and DETEX models include dedicated fire alarm interface terminals that automatically release locks during emergency conditions per building codes.

What's the difference between linear and switching power supply types?

Linear supplies like Securitron BPSH offer cleaner DC output with less electrical noise, while switching types provide higher efficiency in compact enclosures.

How do I connect multiple doors to one power supply unit?

Multi-output models include individually fused channels with supervised outputs. Connect each door's lock to separate terminals for independent control and monitoring.
