The Hikvision DS-K7M-AW50 is a high-capacity power supply box designed specifically for access control installations requiring reliable and continuous power delivery. It can supply power to one access control terminal and one door lock, making it suitable for single-door access control systems in offices, commercial buildings, factories, and restricted areas.
The unit accepts a wide 100–240 VAC input voltage range and provides a regulated 12 VDC output with 50 W power capacity, ensuring stable operation of access control terminals, electromagnetic locks, electric strikes, and related accessories.
For improved system reliability and safety, the DS-K7M-AW50 includes built-in short-circuit protection, excess-load protection, and over-voltage protection. It also supports a storage battery connection, allowing continued operation during temporary power failures when used with a suitable backup battery.
The enclosed power supply design provides neat cable management and secure installation. It is commonly used with Hikvision access control terminals and door locking devices in professional security deployments.
