DROK 12V to 9V 2A 18W DC/DC Buck Power Converter Voltage Step Dowm Power Supply Waterproof

The module is buck power converter, therefore, output voltage must less than input (minimum differential pressure:3V). Output voltage: DC 9V, the output voltage is fixed. With over-temperature, over-current protection. Adopt Synchronous rectification technology, conversion rate up to 90%, low heat and low power consumption. Adopt glue craft, waterproof, anti-shock, moistureproof and dust-proof.
