These DC boost converters are excellent power transformers. They are characterized by wide input voltage, low power consumption, high efficiency and high reliability. They can work safely and reliably in the range of -40°C~80°C Synchronous Rectification Technology Synchronous rectifier circuit adopts MOSFET instead of rectifier diode, which greatly reduces the rectifier loss and improves the efficiency of the converter, the maximum efficiency is above 95%. Intelligent protection Intelligent chip assembly - with over-current, overload, short-circuit, over-electricity, overheating intelligent protection function of good heat dissipation. 100% waterproof module Compact aluminum shell silicone sealing design, with IP68 waterproof, shockproof, moisture-proof, dustproof, heat dissipation and other advantages, to adapt to a variety of harsh environments, to extend the service life. SMT technology F-4 multilayer wires, resistors, capacitors and switching MOS tubes are highly integrated, reliable and stable SMD components. Simple Installation - Positive and negative wires cannot be connected in reverse direction Specifications.
