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%
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.
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.
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.
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.
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.
The coil resistance, which usually ranges between 60 and 80 ohms, determines the exact current. To calculate the current, you can use Ohm's law: I=VRI = frac{V}{R}I=RV. For example, with a 12V relay and a coil resistance of 80 ohms, the current draw would be 150 mA.
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).
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.
A typical TASER device can operate with a peak voltage of 50 kilovolts (1200 Volts to the body), an electric current of 1.9 milliamps, at for example 19 100 microsecond pulses per second.
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.
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.
Any magnetic lock with a holding force less than 1200 lbs. should only be used for traffic control, as would a light or medium duty electric strike. A holding force of 650 lbs. (Figure 1) is typical for most magnetic locks fit for traffic control and they may be easily defeated.
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.
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.
Magnetic locks depend on constant power to remain secure. For this reason, they need a reliable power source. Most maglocks require a dedicated, individually fused, 12VDC or 24VAC power supply. The power supply needs to be hardwired into the buildings electrical system, typically 120VAC.
For commercial and institutional applications, mag locks are normally 12-24VDC powered electromagnets. The amperage draw ranges from approximately 125mA to more than 500mA at 24VDC, and 230mA to more than 600mA at 12VDC. The magnet size, holding force and construction determine the draw.
An automatic door and magnetic lock system also constantly consumes electricity, and even when closed, standby power is used. Magnetic locks use 0.142 kWh to operate for 24 hours, meaning it can cost up to £2.5 per day to power just one door in a building.
For the average door however, the cost is generally about $300.00 installed. Maglocks also come in a number of varieties depending on the strength required. For an average door look to spend approximately $300.00 as well.
Built to last and with virtually no maintenance requirements, they provide an effective form of access control that can be relied upon for years to come. maglocks are an incredibly reliable security measure for any commercial or residential building.
There are two basic styles of magnetic locks, surface mounted and morticed; commonly referred to as shear locks. Surface mounted magnetic locks are available in a range of sizes with different holding forces and can be either monitored or unmonitored, to suit a variety of applications both internal and external.
In review, an oil-filled ignition coil requires about 3-5 amperes of current at 12 volts to produce 20-30 kV, while a modern e-core or coil-on-plug configuration might require as much as 10 amperes of current at 12 volts to produce 30-60 kV of high-intensity spark.
Although acceptable levels of parasitic draw should be kept to a minimum, exceeding 50 milliamps (mA) could lead to battery issues. Generally speaking, an acceptable range for most vehicles falls below 50 milliamps (mA). Anything beyond that could potentially cause problems over time with your 12V batteries.
A 12 Volt Relay usually operates on considerably less than one amp. That's all that it takes to energize the electromagnetic coil to close the relay. A small spring causes the relay to open after the 12 volts going to the coil stops.
