International Safety Standard Approvals
IEC950 Reg. File Number CO24241 (TMH)
TM and TMH SERIES
Single and dual output
[ 2 YEAR WARRANTY ]
2.0 x 2.0 x 0.4 inch package
TMH version certified to IEC950
18-36VDC and 36–72VDC input
Typical efficiency 75%
Isolated outputs
No derating to 70°C
The TM and TMH Series of 5 to 15 watt DC/DC converters from Computer
Products are packaged in the industry standard 2 x 2 inch case. The TMH
version is certified to IEC950 and has an isolation voltage of 3750V. This series
combines three high performance features - wide input voltage range, high
efficiency, and high power density. In addition to this, all outputs are regulated
and isolated from the input. This advance in DC/DC converters is made possible
by implementing a 150kHz switching design in surface-mount technology. With
input voltage ranges of 18-36V, 36-72V and 75% typical efficiency these devices
are ideally suited for on board logic or analog circuits supplied by telecom
distributed power voltages, cellular and telecommunications systems.
SPECIFICATION All specifications are typical at nominal input, full load at 25°C unless otherwise stated
