12V 500W dc to dc Converter Stand-alone DC-DC power supply

This stand-alone power supply is ultra-small in size, has powerful functions, and offers superior performance. The output provides constant current and voltage, with stepless regulation of both voltage and current. It features multiple protections, such as automatic derating for over-temperature, overcurrent, and short circuit scenarios. Additionally, it has the capability to control and monitor input and output, as well as self-diagnose various parameters such as status.

This power supply is primarily used in electric buses, urban trolleybuses, trams, subways, and light rails as a DC power supply. This converter is a high-performance switching power supply that can provide power to 24Vdc power distribution devices and batteries. It can be widely used in pure electric vehicles and hybrid vehicles. High reliability, high efficiency, small size, and light weight are the characteristics of this converter.

The voltage input range is 80-120Vdc DC input, with a single 13.8Vdc output. It comes with a single-chip microcomputer that communicates with the monitoring unit. The internal parameters of the machine can be set or adjusted by the superior monitoring unit through the CAN interface.

Product main features include:

• Small size and light weight, greatly saving space for users
