LI24 Series 24W, SINGLE OUTPUT DIN-RAIL POWER SUPPLIES LI24 is a series of DIN-Rail green power supplies with high efficiency and excellent price/performance ratio provided by MORNSUN. This series provide stability and high immunity against electrical disturbance for loads in industrial process controls, machine tools and other equipment exposed to a difficult industrial environment. Compact size, light weight, standard Din Rail installation(35mm) are other features of these power supplies, which saves a lot of space for your design. Build-in large capacitor provides for you enough hold-up time.

Two same Din Rail power supplies are in use of parallel connection application,Vin1 and Vin2 are both 85-264VAC or 120-370VDC; 2. Adj: Adjusting terminal of output voltage. Users can adjust any load freely within the range of output voltage according to your own need. 3. When AC-DC2’s output voltage is a little lower than AC-DC1’s, AC-DC2 is becoming a spare power supply for load, as Vin1 is off or AC-DC1 is in fault. 4. When Vin1 and Vin2 are supplying power to Din Rail power supply alternately, Din Rail power supply will work alternately and supply power to load sostenuto. For any design change and upgrade, we will not make any prior notification A/0-2007 Page 2 of 2
