Features: Ultra- low input/output differential pressure. Input voltage : 8-30V, 30-60V, Output voltage: 12-130V. 1mm double wire winding inductor, high quality filter capacitor, boost output power preferably. With voltage regulation, current regulation potentiometer, can adjust the output voltage & current at any for time. The input undervoltage for protection function is especially applicable to batteries and solar- panels to prevent battery overdischarge and solar panel voltage from being too low to start the module.
