The Dilong 4kW Open Frame DC DC Converter is a high-power, modular solution for demanding automotive and industrial applications. It efficiently steps down a high-voltage DC input of 560V to a stable 14V output, providing a robust 4000-watt power supply. This makes it an ideal core component for electric vehicle auxiliary systems, high-power charging setups, or custom energy conversion projects where reliable, high-current low-voltage power is essential. Built with a modular open-frame design, it offers flexibility for integration into larger systems or enclosures. The unit is engineered for stable performance, ensuring consistent power delivery for sensitive electronics and high-demand loads. For system integrators and engineers working on EV conversions, commercial vehicles, or specialized power distribution, this converter provides a solid, high-capacity foundation.
