Best Choice for 48V Automotive Power System Testing Brand New 100V DC Power Supply with Auto-Ranging Output 10kW~150kW
2017/10/17

As the trend for global energy conservation and carbon emission reduction leads the evolution of new energy vehicle electrical systems, the world’s major car manufacturers have proposed 48V power system and LV148 regulatory standards for testing new vehicles. Comparing to the previous 12V power system, 48V power system has higher conversion efficiency and increased stable start-stop performance. In addition, the server power supply structure is also moving from conventional 12V to 48V in order to optimize the overall system power conversion efficiency.

Chroma launches a new 100V DC power supply, Model 62150H-100P, with auto-ranging output feature to support 40V/50V/60V/…/100V voltage ranges and output up to 15kW full power. It is suitable for testing products with different specifications such as the 48V new energy vehicles from 0V to 60V and the 48V architecture for server power and telecom power. The DC power supply is able to output the power from 10kW up to 150kW when setup in parallel under master/slave structure. It has active current sharing and fast transient response functions with active PFC to put low energy consumption and high conversion efficiency into effect to save energy.

High Accuracy and High Stability
The voltage control accuracy on the front panel and through the communication interface is up to 0.05% allowing users to set the required output. The stability of constant voltage and current is 0.005% for 8 hours operating. The temperature coefficient of drift is 0.005%/°C that provides an accurate and stable power source steadily even after long hours of operation.

Voltage/Current Slew Rate Control
The DC power supply’s voltage slew rate control is from 0.001V/ms to 5V/ms and can integrate with an automatic programming mode to meet the diversified needs of specific applications such as automotive electronic systems. Chroma incorporates the ISO 16750-2, VW 80000 and GS 95024-2 international automotive electronics standards into the GUI, Softpanel, to help users speed up the development and testing task.
