Product Overview
Description
The DC-DC converter is optimized and designed for electir car ,air conditioning of electric car or battery , it uses natural cooling, can work at high temperatures without derating. It have ultra-small size (size: 252 * 188 * 90mm), over-temperature automatic derating, over-current, short circuit and other multiple protection, also have input and output status and other parameters of the monitoring and self-diagnostic function. input volt. range 200-500Vdc DC input, single Circuit 48Vdc output. With input undervoltage alarm and protection, output overcurrent alarm and protection, output overvoltage protection, output short circuit protection, over temperature alarm and protection, output reverse polarity protection
Strengthen the production process design, strict selection of devices, to ensure product reliability and the mechanical s
Small volume, light weight, save space for the user greatly
System environment to a wide temperature range -40 ℃ ~ + 65 ℃, intelligent temperature derating; overtemperature protection
Soft switching control technology, the system for maximum efficiency ≥ 95%.
Program online upgrade function, Convenient customer online debugging program and real-time updates, online self-diagnostic function, easy system maintenance.
