DC/DC Converter

Description

The RSK-RUW series is a state-of-the-art isolated DC/DC converter that boasts an ultra-wide 8:1

input voltage range of 4.5-36 VDC. The RSK-RUW also includes ON/OFF control for added convenience

and precision. The device delivers high accuracy and tight line and load regulation, ensuring stable

performance even in challenging conditions. The RSK-RUW also includes continuous short circuit

protection and undervoltage lockout (UVLO) for added safety and security. This product is certified

according to IEC/EN/UL 62368-1, making it suitable for use in a variety of industrial applications. With

a maximum output power of 2W and the ability to operate at 0% minimum load, the RSK-RUW is very

versitile. The device also offers high efficiency, with a typical value of 88.5%. Finally, the RSK-RUW

offers basic grade isolation of 3kVDC/1min and an industrial operating temperature range of -40°C to

85°C without derating, making it ideal for use in demanding industrial environments.
