These dc buck boost converters are excellent power transformers. They feature wide input voltage, low power consumption, high efficiency, great reliability. They can work safely and reliable in -40°C~80°C range. Widely used to golf cart, motor, speaker, GPS, LED car display screen, air-conditioner, electric fan, solar energy, photo-voltaic power, DVD, industrial equipment ect.
 Synchronous Rectification Technology
The synchronous rectifier circuit use MOSFET instead of rectifier diode to greatly reduce the loss of the rectifier and improve the converter efficiency, Maximum Efficiency:≥95%
 Intelligent Protection
Assembled with smart chip--has features of Over-current /Over-load /Low-load /Short-circuit /Over-heat intelligent protection
100% Waterproof Module
Compact aluminium shell with epoxy potting is IP68 waterproof, anti-shock, damp-proof , anti-dust protection  and better heat dissipation, adapt to a variety of harsh environment and extend service life
SMT Process
FR-4 multilayer lines, resistors, capacitors and switch MOS tube are SMD components with high integration, high reliability, high stability
Easy Installation---Positive and negative wires can’t be reversed connection
Notes: It's normal that the case is hot when converter inside temp is over 113℉, converter will protect itself when inside temp is over 185℉.
