Traco Power Non-Isolated DC-DC Converter, 5V DC Output Voltage Rating, 83% Efficiency - TSR 1WI Series - TSR 1-4850WI

Rev up your low-voltage applications with this non-isolated DC-DC converter from Traco Power. It's a POL device that steps down incoming voltages to a safe 5V DC to ensure effective performance. A robust SIP-3 package insulates live components, protecting them from damage and you from electric shock. Thanks to the wide input voltage range between 9 and 72V DC, this versatile unit is compatible with commonly used power supplies. With its 83% efficiency, it significantly reduces electrical losses and keeps the heat down, providing you with a low-waste power solution.

• Wide operating temperature range between -40°C and +80°C for use in harsh conditions
• Integrated short-circuit protection helps to prevent damage and service interruptions

Applications

• Portable gaming consoles
• Digital cameras
• Medical devices
• Measuring and testing instruments

The Tracopower TSR 1WI is a non-isolated POL converter series with an ultra wide 8:1 input voltage range which comes in a standard SIP-3 package. Covering the majority of standard bus- and battery voltages this POL converter is a versatile solution for many applications in distributed power systems where different input voltages have to be handled. With 0.6A max. output current and standard features such as low standby current, precise regulation and protection against short circuit, overvoltage and overload the TSR 1WI is suitable for many battery and distributed power applications.
