The professional APS-412 buffer power supply is an advanced switching device designed to ensure power continuity in security systems such as alarm installations, access control systems, CCTV video monitoring, and intercoms. Thanks to its high 4A output current efficiency and stable 12V DC output voltage, this power supply is ideally suited for powering alarm control panels, sensors, cameras, and keypads. The device is adapted for mounting on a standard DIN rail (TS-35), which significantly facilitates installation in distribution boards and control cabinets.
A key advantage of the APS-412 power supply is its buffer function, which automatically switches the power source to a backup battery in the event of a 230V AC mains failure, ensuring uninterrupted operation of connected receivers. The product is characterized by high energy efficiency and a low level of generated noise, which is crucial for sensitive electronic systems. Additionally, the device is equipped with a dedicated connector that allows direct communication with Satel brand devices, enabling full integration and power status monitoring from the alarm system level.Operational safety is ensured by extensive protection mechanisms, including short-circuit, overload, and overvoltage protection. The power supply also features an intelligent battery charging circuit with selectable current (0.5A or 1A), allowing for optimal matching to the capacity of the battery used. Clear optical signaling and OC-type technical outputs inform about the status of the mains power, battery charge level, and any overloads, making this model one of the safest solutions on the installation market.Power supply type
Switching, buffered, designed for continuous operation in security systems.
Input voltage
230 V AC (alternating current), stable operation at standard power grid parameters.
Output voltage
12 V DC (direct current), perfectly matched to alarm electronics and CCTV cameras.
Current efficiency
4 A - total capacity for powered devices and battery charging.
Device power
48 W rated power ensuring high stability under load.
Battery charging
Charging current selectable via jumper: 0.5 A or 1 A; support for lead-acid batteries.
Protections
Short-circuit (electronic fuse), overload, overvoltage, reverse battery connection, and deep discharge protection.
Optical signaling
LED indicators for mains power presence, charging process, and output voltage status.
Technical outputs
WS (AC failure), WB (low battery), WP (output overload) - open collector (OC) type outputs.
Dedicated connector
Special Satel socket enabling communication with control panels and modules for power status monitoring.
Housing
Made of durable plastic, providing insulation and component protection.
Mounting
On standard 35 mm DIN rail (TS-35), takes up width consistent with cabinet modules.
Operating conditions
Indoor operation, standard operating temperature range for professional electronics.
Software and logic
The device has a built-in processor managing diagnostics and the charging process. The logic system monitors voltage and current parameters in real-time. If a mains power failure is detected, the algorithm immediately switches the source to the battery without interruption to the receivers. System logic protects the cell from permanent damage by disconnecting it when the voltage drops below a safe threshold (UVP function). An implemented test sequence allows for automatic reporting of system status to the alarm control panel via a dedicated bus or OC outputs.
