DC electromagnetic locks combine the general advantages of electromagnetic locks with the specific characteristics of DC power supply, making them widely used in access control systems.
Automatic unlocking upon power failure, compliant with fire safety regulations: The magnetic force of a DC electromagnetic lock disappears immediately after a power outage, automatically unlocking the door and ensuring rapid evacuation in emergencies, meeting national fire escape safety requirements.
No mechanical wear, long lifespan, and low maintenance costs: Utilizing pure copper coils and alloy suction plates, eliminating traditional lock tongues and other mechanical structures, avoiding jamming and wear issues, resulting in approximately 60% lower maintenance costs compared to electric bolt locks.
Quiet operation, suitable for noise-sensitive environments: Producing only a slight sound of ≤40 decibels during engagement, far lower than the 60-70 decibels of electric bolt locks, suitable for offices, residential areas, hospitals, schools, and other locations.
Easy installation, compatible with various door types: No need to damage the door structure; can be installed on wooden doors, glass doors, metal doors, fire doors, etc., and supports... 12V/24V dual voltage adaptive, facilitating upgrades to older access control systems.
High security and resistance to force: Mainstream models boast a static suction force of up to 280kg (560kg for double-door models), effectively resisting impacts or prying by multiple people; some products feature anti-tamper and anti-pry designs, and integrate surge absorption and residual magnetism protection functions.
Low power consumption and high reliability: Operating current is typically ≤250mA (DC12V), with built-in protection circuitry ensuring stable operation and suitable for long-term continuous use.
