The TRACOPOWER TMR 4WI is a regulated 4 Watt DC/DC converter series with 4:1 input voltage range. It comes in a compact SIP-8 package featuring single and dual output models, I/O isolation voltage of 1600 VDC and protection against short-circuit and over load. Being a 4 Watt converter this series acts as an excellent gap closer between the more common 3 & 6 Watt converters. It offers a cost-efficient alternative to 5 and 6 Watt converters in applications where a 3 Watt converter would operate at the absolute technical limits (e.g. output power).

Compact SIP-8 package
Wide 4:1 input voltage range
Temperature range –40° to +70°C without derating
High efficiency up to 83%
I/O isolation 1600 VDC
Protection against short-circuit and over load
