HHKT3000-27F Series DC-DC converter specification
The HHKT3000-27F power supply has two types of HHKT3000-27F power supply: H (high-level enable effective) and direct output after power-on.
The control method is optional.
The power supply has powerful functions and superior performance. The output has the functions of constant current, constant voltage and stepless voltage regulation; it has automatic derating of over-temperature, over-current, short-circuit, etc.
Heavy protection, with monitoring and self-diagnosis functions for various parameters such as input and output status.
The power supply is mainly used for electric passenger cars, urban trolleybuses, trams, subways and light rails, as a DC power supply. This converter is high performance
The switching power supply can supply power for car lights, wipers and horns, as well as car DC air conditioners. 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.
1.1 Product features
Input: 200~850VDC; output voltage range: 16~27.5VDC; rated output current 120A.
* The working environment temperature range of the system is wide to -40ºC~+75ºC (when the temperature is ≥55ºC, the power output will be reduced);
* Adopt novel soft switch control technology, the highest system efficiency ≥ 96%;
* Core technologies:
Boost Power technology, the instantaneous power of the module can reach more than 150% of the rated power, and the duration can reach 2 seconds;
Monitoring program based on module self-diagnosis and CAN communication, real-time understanding of the status of the module and recording of the historical operating data of the module;
Program online upgrade function, convenient for customers to debug online and update the program in real time;
* Enhanced process design and strict device selection ensure the reliability and mechanical strength of the product;
* Complete fault alarm and protection functions, including:
Input over-voltage and under-voltage protection, output over-voltage, under-voltage, over-current, short-circuit protection, etc.;
Input anti-reverse protection;
Intelligent temperature derating; over-temperature protection;
* High-speed CAN communication bus to realize the real-time detection and monitoring function of the power module;
* With online self-diagnosis function, convenient for system maintenance;
* Small size, light weight, greatly saving space
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
