Access Control Power Supplies & PSUs

Access control power supplies and PSUs for electric locking, door entry and security installations. Choose 12V and 24V power supplies including DIN rail modules, boxed battery-backup PSUs, monitored units and fused multi-output supplies.

Access Control Power Supply Units

A correctly sized PSU provides reliable power for maglocks, electric strikes, keypads, controllers, readers and other access control equipment. Select the required voltage first, then choose a current rating above the total connected load with suitable allowance for accessories and future expansion.

12V Access Control Power Supplies

Our 12V range includes 13.8V and adjustable 12–14V DC charging supplies as well as DIN rail and boxed units. Battery-backup and monitored options are available for installations requiring continued operation or PSU status monitoring.

24V Access Control Power Supplies

24V systems may use 24V, 24–28V or 27.6V DC supplies depending on the equipment and PSU design. Always check the voltage and current requirements of every connected device before selecting the power supply.

Choosing the Correct PSU

Use the collection filters to narrow the range by voltage and current. Check enclosure size, battery capacity, monitoring, output protection and the individual product specification before ordering.
