Power Supplies for Door Hardware and Access Control

Every electric lock, magnetic hold-open and electrified exit device needs a reliable power source behind it. The rest of the system is only as dependable as the power supply running it.

Door Lock Power Supplies for Consistent Performance

Voltage fluctuations and insufficient amperage are two of the most common causes of electric lock failure. Our door lock power supplies are rated for the hardware they support and deliver stable output under real load conditions.

Commercial Door Power Supplies Built for Continuous Use

Residential power supplies are not rated for the duty cycle that commercial door hardware demands. Our commercial door power supplies run continuously without overheating and include battery backup inputs for power failure scenarios.

Choosing the Right Door Power Supply

Output voltage, amperage, number of outputs and enclosure type all factor into the right choice. A single electric strike has different requirements than a system with multiple locks, a rex device and a mag-hold all on the same circuit.

One Source for Door Hardware Power

We carry power supplies that work across the most common electric lock and access control brands so you can source everything for a project in one place.

Frequently Asked Questions

Electric locks, maglocks and electrified exit devices all have specific voltage and amperage requirements. A dedicated power supply ensures stable output and protects the hardware from fluctuations.

No. Door lock power supplies are purpose-built for continuous operation and consistent output. A generic adapter is not rated for the duty cycle that electric door hardware demands.

Depends on the lock configuration. This is why most commercial power supplies include a battery backup input to keep doors operating during an outage.

Add up the amperage draw of every device on the circuit, locks, request-to-exit sensors, door position switches. The power supply needs to handle the total load with some headroom.

Yes, commercial door power supplies typically have multiple outputs to run several devices from a single unit.

No. They are typically mounted in an electrical enclosure near the door or in a central equipment room, with wiring running to each device.
