The TMR 4 is a regulated 4 Watt DC/DC converter series with 2:1 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-effi-
cient alternative to 5 and 6 Watt converters in applications where a 3 Watt con-
verter would operate at the absolute technical limits (e.g. output power). The in-
telligent design provides efficiencies up to 87% and a temperature range of
-40°C to +70°C without derating which enables an unrestricted use of this
converter series in applications with demanding temperature requirements. Ad-
ditionally, 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 is designed to deliver a high quality, cost efficient
and compact solution for many applications.
