Calex BCE 750W Bi-Directional IP-Rated DC/DC Converters
Calex BCE 750W Bi-Directional IP-Rated DC/DC Converters provide a complete solution for in-vehicle power distribution with 12V/48V battery configurations. These Calex 750W non-isolated DC/DC converters are designed for a variety of applications, including micro and mild hybrid automotive systems. BCE Bi-Directional DC/DC Converters charge a low-side (12V) battery during normal operation (buck mode) and charge or assist the high voltage (48V) battery in emergency situations (boost mode). The 48S12.750BCE is packaged in a low-profile 4.84" x 6.97" x 1.75" (123mm x 177mm x 44.5mm) mechanically enclosed IP67-rated package weighing 3.04 pounds. The package makes the unit ideal for harsh shock and vibration requirements and easy integration with a battery pack.
