Product Description

The PUS 2440-15 is a compact, uninterruptible DC UPS module. In addition, the connected batteries are charged at up to 15 A, monitored and kept ready for use. In the event of an input voltage failure (power cut, brief interruption, overload), the unit switches to UPS mode and continues to supply the loads without interruption. The high charging current allows the connection of high-capacity batteries, thereby ensuring long backup times in the event of a mains failure.
