DC-DC Converter "RSDH Series" for Communication Base Stations
Achieves stable power supply even in high voltage DC environments. An isolated converter that supports signal amplification for communication equipment.
In communication base station signal amplification equipment, a stable power supply is essential for maintaining communication quality. Particularly in high-voltage environments, there is a risk that voltage fluctuations and noise can adversely affect the operation of signal amplifiers, necessitating the establishment of a reliable power supply environment. The RSDH Series supports an ultra-wide input range of DC250V to DC1,500V and, with its low ripple and low noise design, provides a stable DC power supply to control equipment even in high-voltage environments. 【Usage Scenarios】 - Power supply to signal amplifiers in communication base stations - Operation of communication control equipment in high-voltage DC environments - Long-term operation in outdoor and harsh environments where dust and dirt are concerns 【Benefits of Implementation】 - Supports stable operation of signal amplifiers through low ripple and low noise design - Internal coating makes it resistant to dust and dirt, enabling long-term operation - Flexible adaptation to various high-voltage DC environments due to wide input voltage compatibility
