The TEN 50 Series is a range of isolated high
�������������������������������������
performance dc-dc converter mod�
ules. Due to the very high efficiency of up to 92% and the use of highest reli�
able components these 50 W converters come with a footprint of only 1.0” x
2.0”. The 12 models have a wide 2:1 input voltage range and a tight output volt�
age regulation. They do not need a minimum load and a offer a high efficiency
also at low load conditions. The output voltage is adjustable by external resistor.
Remote On/Off and protection against overload and short circuit are standard
features of these converters.
Typical applications are in mobile equipment, instrumentation, distributed power
architectures in communication and industrial electronics and everywhere where
space on the PCB is critical.

Note:
Before attaching the heatsink, the product
label on converter has to be removed for
optimal performance.
For volume orders we can supply the
