AC-DC power converter: input voltage is 10-28V AC, output voltage is 12V DC; maximum output current is 5A; no-load current is 10mA; operating temperature range is -40 degrees Celsius to 80 degrees Celsius. Waterproof design: IP68 rated for protection against dust and water; housing constructed with flame-retardant plastic and encapsulated with epoxy resin for enhanced durability, corrosion resistance, and water resistance; suitable for short-term underwater use. High efficiency: built-in switching regulator module delivers up to 96% conversion efficiency. Multiple protections: equipped with over-voltage, over-current, over-temperature, and short-circuit protection through integrated micro-processing chip for reliable operation. Wide application: compatible with car monitors, surveillance cameras, fans, water pumps, motors, routers, and other 12V DC powered devices.
