Input voltage up to 75 volts, output voltage up to 50V (at input 75 volts) maximum current 25A. Wiring: For high power, the wiring should be as thick as possible. Continuously adjustable output voltage and current The module adopts step rectification scheme with high efficiency, the highest efficiency is up to 95%. Conversion efficiency: up to 95% (efficiency is related to input and output voltage, current and differential pressure); Short circuit protection: Yes (constant current protection); Input reverse connection protection: no; Output anti-refill: no (to charge the battery, the output connected to inductive loads, such as connecting the motor must be added anti-refill diode), Manufacturer: Littimoon
