Compared to the previous 12V power system, the 48V power system offers higher conversion efficiency and more stable start-up and shutdown performance. Furthermore, the server's power supply structure is also being upgraded from the conventional 12V to 48V to optimize the overall efficiency of the system's power conversion.

Chroma has launched a new 100V DC power supply, model 62150H-100P, featuring auto-ranging output to support voltage ranges of 40V/50V/60V/.../100V and a maximum power output of up to 15kW. It is suitable for testing products with various specifications, such as new 48V power vehicles (0V to 60V) and 48V architectures for server and telecom power. The DC power supply can generate power from 10kW to 150kW when configured in parallel under a master/slave structure. It features active current switching and fast transient response with active PFC for low power consumption and high conversion efficiency, resulting in energy savings.
High precision and high stability
The accuracy of the voltage control on the front panel and through the communication interface is up to 0.05%, allowing users to configure the required output. The stability of the constant voltage and current is 0.005% over 8 hours of operation. The temperature drift coefficient is 0.005%/°C, ensuring consistently accurate and stable power even after extended use.
