240-400W Wide input DC/DC Converter with 1/8-Brick Package - VCB48_EBO-xxWR3-N Series

Introduction

MORNSUN launched a new series of DC-DC converters to meet the growing demand for medium and high-power power supply in various fields, including telecommunication, electric power, and industrial control. The 1/8-brick VCB_EBO-xxWR3-N series, output power covers 100W, 240W, 300W, and 400W.  These products meet IEC/UL/EN standards and DOSA standards with a wide operating temperature range, high efficiency, and low ripple noise. Meanwhile, their comprehensive protections ensure that customers do not suffer unnecessary losses from abnormal operation of their system or equipment.

Advantages

1. High and stable efficiency curve

5G communication data traffic can be quite unbalanced, with significant variations in different periods. As a result, the actual load range of the power supply may vary greatly from light load to full load. To improve efficiency, it's not just about full load efficiency, but also the stability of efficiency at different load points.

MORNSUN has developed a technology that can effectively improve the conversion efficiency of power supply under various loads. This means that the average efficiency of power supply at the four load points of 10%, 25%, 50%, and 100% is over 90%, which is quite impressive.

2. Outstanding and comprehensive performance

VCB_EBO-xxWR3-N is designed to meet IEC/UL/EN62368 and DOSA. Its operation temperature range is -40℃ to +85℃ and it has a remarkable temperature derating curve. With an isolation voltage of 1500VDC, low ripple noise of 100mV (typ.), and output efficiency of up to 95%, it is clear that this series is designed to deliver optimal performance. It also has protection functions, such as input under-voltage protection, over-current, over-temperature, and short-circuit protection, to prevent abnormal system operation and unnecessary losses.

Applications

VCB_EBO-xxWR3-N can be widely used in various fields such as telecommunication, industrial control, electric power, and instrumentation. These products have many typical applications including servers, base stations, relay systems, etc.
