The MA lock can be specified in a 12 or 24V DC configuration (default is 12V). Additionally, an AC power source may be used as long as a rectifier is installed in the circuit (not provided). Here are the electrical requirements for both: Voltage: 12V DC +/- 10%
Magnetic locks are always DC devices and maybe be 12 or 24vDC. This specification allows for a single maglock which controls an entrance door. A separate push button will release the lock when pressed.
Amperage selection – our recommendation, particularly when using a device that is permanently powered (such as a failsafe maglock) is to use a power supply that provides double the amperage to the devices being powered. For example a ML600-D-M maglock has 2 maglocks each requiring 480mA of current, totalling 960mA.
Resolution: Do magnetic locks take AC voltage? No, maglocks only take 12 or 24 volts DC from a filtered and regulated power supply, generally at less than 1 amp @ 12vdc, and . 5 amp @ 24vdc. AC power will destroy the maglock and / or the maglock control module, and will void the maglock warranty.
That's the same as 3.48 Watts, or 0.00348 kW. For 24 hours of powering the new maglock, the equivalent cost is 2.42 pence.
Alongside the holding force, you also need to consider the power consumption of the door lock. This dual voltage wiring 12V/24V maglock has a 140mA current draw at 12V DC, so a low 70mA current draw at 24V DC.
Maglocks require constant power to stay locked, making them fail-safe. If the power goes out for any reason, the maglock's magnetic hold will release and the opening will no longer be secured. On the other hand, fail-secure locking functions require power to unlock a door.
Electrical requirements
The power for an electromagnet lock is DC (direct current), around 5–6 W. The current is around 0.5 A when the voltage supply is 12 VDC and 0.25 A when using 24 VDC (varies between manufacturers and if there are one or two coils in the block).
The maximum voltage supplied is as follows: 14.5 V DC for the 45 W units supplied with MacBook Air. 16.5 V DC for the 60 W units supplied with MacBook and 13" MacBook Pro. 18.5 V DC for the 85 W units supplied with 15" and 17" MacBook Pro.

For connecting an electric strike or a mag lock to the ACU, use 18 gauge 2 conductor cables. For exit and egress devices, use 22 gauge 4 conductors (or 6 conductors depending on the egress device) cables.
Facts: - - Most Maglocks DO NOT require a diode to be added by the installer.
If a magnetic lock is buzzing or noisy it could be the result of an AC component riding on the DC supply voltage. Using a meter, check for AC riding the DC level. If possible test the mag lock with 12 or 24 batteries.
An HES 9600 electric strike can draw power from either a 12-volt or a 24-volt power source. It draws current equal to 0.45 amps at 12-volt, but only 0.25 amps at 24-volt. These numbers indicate a requirement of about half an amp at 12-volt but just one-quarter of an amp at 24-volt.
The requirement of electric locks generally use 12 volts dc or 24 volts dc and 12volt ac and 24 volt ac. the power supplies step the power down from the mains to the required range of 12 or 24 volts The standard range is 1amp ,two amps , three amps of five amps.
Generally speaking, the cost to install a maglock on an average door is approximately $300. Nonetheless, installation costs will vary based on the complexity of the installation and the installer you use.
*The MagSafe Charger will also function with power adapters that provide a minimum 12W (5V/2.4A) of power, but this will result in slower charging.
The Arrival of iPhone 15: With the launch of iPhone 15, Apple transitioned from Lightning to USB Type-C, rendering the Lightning-based MagSafe products less compatible. This change likely signals an upcoming refresh of accessories to align with the new Type-C standard. 🔌
If you have an iPhone 16 or iPhone 16 Pro, you can get faster 25W charging using a MagSafe charger that's connected to a 30W or faster power adapter.
I have also seen ratings of 320ma to 640ma depending on brand, type (Double v/s single), and voltage (12vdc/24vdc). 24vdc mags locks have a lower current requirement. Most maglocks are multi voltage.
Magnetic locks require a constant source of power to keep the door locked. The current used by the electromagnetic lock is around 0.5A when the voltage supply is 12VDC. The current used by the electromagnetic lock is around 0.25A when the voltage supply is 24VDC.
Magnetic locks require a constant electric current to remain locked, but they are designed to use a low voltage, making them relatively energy-efficient. Modern mag locks are also being designed with energy-saving features to reduce electricity usage further.
One of the most common problems with maglocks is a power failure. This occurs when the lock doesn't release or engage due to a lack of power. Possible causes of power failure include a dead battery, a tripped circuit breaker, or a malfunctioning power supply.
The primary difference between electric strike locks (door strike) and magnetic locks (maglocks) is their power requirement. Maglocks are fail-safe, while electric strikes are generally fail-secure. In other words: Magnetic locks require power to lock the door, whereas electric locks require power to unlock the door.
A holding force of 650 lbs. (Figure 1) is typical for most magnetic locks fit for traffic control and they may be easily defeated. However, this is a benefit compared to the use of light duty electric strikes.
