18-75V Ultra-wide Input Voltage DC/DC Converter URF48xxQB-100WR3 Series

Along with the upgrading of traditional manufacturing and increasing input in industrial automation, traditional industries such as industrial control and communication industries increase their demand for medium-power DC/DC power supply. Following the trend, MORNSUN introduces a new 100W DC/DC converter—URF48xxQB-100WR3 series which are of 18-75V ultra-wide input voltage and can be widely used in industrial control, communication, electricity and railway; such as intermediate bus of Industrial control system, distributed power system, wireless network equipment system, medium and high power control system, and long-distance DC power supply system.

With efficiency up to 94%, URF48xxQB-100WR3 series seek for further “cost reduction and efficiency improvement”. In addition to quality guarantee, service assurance and technical support, this series also provide customers with better choice with its high reliability and excellent performance.

With continuation advantages of R3 DC/DC converters, the converters of wide input voltage keep extending profiles. URF48xxQB-100W/150WR3 and URF48xxQB-75WR3 will come soon.

Intelligent Inspection Robot for Power Substation
Intelligent Inspection Robot for Power SubstationIntelligent substation inspection robots all day and night inspect the power transmission equipment to monitor and ensure the safety of equipment, including data collection, video surveillance, temperature and humidity, pressure measurement. When accidents occur, the robot can even identify equipment failure replacing staff and protect the staff from safety risk.

The robot requires strong endurance and has a higher requirement for power module. The two 100W DC/DC converters offering 4:1 input voltage(18-75V ) and high efficiency in the application form a dual drive, simplifying circuit design and reducing power consumption.
