Characteristics: This voltage converter uses a high-quality industrial-grade chip with high conversion efficiency and stability. Supports 3 intelligent protections, including over-current protection, over-temperature protection, and output short-circuit protection. Copper wire provides excellent electrical conductivity, low operating temperature, low carbon content, and improved energy efficiency. Fireproof plastic housing and organic silicone sealing technology offer high thermal conductivity, IP67 rating, water resistance, and shock resistance. Suitable for use with car stereos, radios, monitoring systems, LED displays, electric fans, motors, and other electronic devices.
