The advantage of the power supply is its high energy efficiency reaching 87%, which minimizes energy losses and reduces component heating. The device offers intelligent battery charging management with selectable charging current (1A, 2A, or 4A), allowing for optimal compatibility with various cell capacities. In the event of a mains power failure, the power supply immediately switches to battery mode, ensuring continuity of facility protection.
The product is equipped with an advanced diagnostic system with OC-type technical outputs that signal the absence of AC power (EPS) and battery failure or absence (APS). A robust metal housing with space for two 12V/18Ah batteries provides mechanical protection and aesthetic installation. Additional features, such as a dynamic battery test and deep discharge protection, guarantee the longevity of the emergency power system. The power supply also features a built-in forced cooling fan, which is crucial when operating under high loads.
