TRACO Power's TIB 240-124BCMU module turns any existing AC/DC 24 VDC power source into a full-fledged uninterruptible power supply (UPS) system supporting up to 240 W of power, optimally charging and protecting connected lead-acid batteries. An integrated microprocessor ensures that the connected lead-acid battery is optimally charged with periodic impedance measurements performed to alert the user in the rare case of a battery failure or disconnection. During battery backup operation, the internal DC/DC power conversion stage keeps the output voltage constant while the battery terminals are protected with a user-serviceable 15 A blade-type fuse. The TIB 240-124BCMU has been qualified to UL/EN/IEC 61010-1 standards for measurement, laboratory, and control equipment, as well as EN 62040-1 for uninterruptible power supplies. It also comes with an internal Class B EMI filter for EN55011 and EN55032 compliance.
