The Satel APS-412 is a high-performance buffer power supply for the reliable power supply of 12-volt security devices. It was developed specifically for applications in alarm systems, access control systems, video surveillance, and other security-relevant installations and ensures a stable energy supply even during power outages.

The switched-mode power supply provides a stabilized output voltage of 12 V DC with a total current capacity of up to 4 A, making it ideal for operating alarm control panels, expansion modules, sensors, or communication devices. Thanks to the integrated buffer function, a 12 V lead-gel battery can be connected, which automatically takes over the power supply in the event of a mains failure, thus ensuring uninterrupted operation.

The APS-412 meets the requirements of standard EN50131-6 Grade 2, making it suitable for professional intrusion detection systems and security-critical applications. The efficient switched-mode power supply technology ensures a stable energy supply without an additional mains transformer and guarantees reliable continuous operation.

For additional operational safety, the power supply unit features several protection functions, including short-circuit, overload, and deep discharge protection for the connected battery. At the same time, status indicators and signal outputs allow for easy monitoring of mains power, battery, and system status.

Thanks to its flexible design, the Satel APS-412 can be mounted both in suitable SATEL enclosures and on a DIN rail. This allows it to be easily integrated into existing security installations and makes it suitable for professional applications in building security, alarm technology, and automation.
