The TMR 4 and TMR 4WI are a set of regulated 4 Watt DC/DC converters with either 2:1 (TMR 4) or 4:1 (TMR 4WI) input voltage range. They come 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 4 Watt converters these series act as excellent gap closers between the more common 3 & 6 Watt converters. They offer 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).



The intelligent design provides efficiencies up to 87% and a temperature range of -40°C to +70°C without derating which enables an unrestricted use of these converter series in applications with demanding temperature requirements. Additionally, the integrated remote On/Off function offers a convenient way to control your application. Certified according to the latest IEC/EN/UL 62368-1 industrial standard the TMR 4 and TMR 4WI are designed to deliver a high quality, cost efficient and compact solution for many applications.
