Achieves stable power supply even in high voltage environments. An isolated DC-DC converter that demonstrates reliability under harsh conditions.
In defense-related fields and critical infrastructure facilities, high reliability is required to continuously supply stable power to control equipment under any environmental conditions. Especially in high-voltage DC environments, a power supply system that is less susceptible to voltage fluctuations and external environmental influences, and that operates stably over long periods, is essential. Inadequate power supply poses risks of equipment malfunction or shutdown, making products with robust design and high insulation performance crucial. The RSDH Series supports ultra-wide input from DC250V to DC1,500V and features environmental resistance due to internal coating, making it ideal for environments where stable power supply is required. 【Usage Scenarios】 - Stable power supply to control equipment in high-voltage DC environments - Harsh operational environments prone to dust and dirt - Power supply units for critical systems that are expected to operate long-term 【Benefits of Implementation】 - Ultra-wide input support maintains stable operation in diverse high-voltage environments - Internal coating enhances resistance to dust and dirt, improving reliability for long-term operation - Reinforced insulation design with AC4,000V between input and output ensures overall system safety
