TMR 4 Series DC/DC converter for industrial applications

23rd November 2020

The TMR 4 and TMR 4WI are a set of regulated four 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 four watt converters these series act as excellent gap closers between the more common three and six watt converters. They offer a cost-efficient alternative to five and six watt converters in applications where a three 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 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.
