DC/DC Converter TMDC 40 Series, 40 Watt Fully encapsulated low profile plastic case Ultra wide 4:1 input voltage range Operating temperature range 40C to +85C I/O isolation 2500 VDC Excellent efficiency up to 92 % Input filter to meet EN 55022, class A Optional DIN-Rail mount adapter No minimum load required Power good LED indicator and remote on/off function UL 62368-1 IEC 62368-1 3-year product warranty The TMDC 40 Series is a range of encapsulated high performance DC/DC con- verter modules. With a very high efficiency of up to 92% and the use of highest reliable components these 40 W converters are avialable as a chassis-mount with screw terminlas or PCB versions. The 8 models have a wide 4:1 input volt- age range and a tight output voltage regulation. They do not need a minimum load and offer a high efficiency also at low load conditions. They feature a re- mote control input and a green power good LED which indicates the presence of the output voltage. Protection against overload and short circuit are standard features of these converters. EMC characteristics and safety certifications are aligned for the operation in industrial environment.
