The SPUC24720 is a DIN rail mounting UPS controller designed to establish an uninterruptible power supply for 24VDC systems. It operates with a nominal 24VDC input (22.5V to 28V range) and delivers up to 720W of power with a maximum output current of 30A. The controller features selectable charging currents for lead-acid batteries, built-in battery test functions, and polarity protection. Status is provided via LED indicators and three SPDT relay outputs for DC OK, battery fail, and backup mode signals. This device is ideal for applications requiring reliable DC power backup, ensuring continuous operation of critical loads during power failures.
