The MZB-312-17 floating-operation power supply is a reliable device designed to power low-current systems that require continuous operation and to provide backup power in the event of a power grid failure. The 13.8 V output voltage and maximum output current of 3 A ensure a stable power supply for devices used in alarm, access control, and monitoring systems. The unit is equipped with two independent, protected outputs, which allow for the safe powering of various system components from a single source. The security buffer power supply works with a battery with a capacity of up to 17 Ah, and the option to select a charging current of 0.5 A or 1 A allows for optimal adjustment of operating parameters to the battery in use. Built-in protections against short circuits, reverse battery connection, and over-discharge enhance operational safety and protect connected devices. The buffer power supply is manufactured in accordance with the requirements of the EN 50131-6 standard, Grade 2. Its compact housing, measuring 230 × 230 × 90 mm, facilitates installation in various types of low-current systems.
