Description
The KSTW004A2B series power modules are isolated DOSA compliant 1/16 th brick dc-dc converters that operate over an ultra-
wide input voltage range of 36 V
dc
-75V
dc
and provide a single precisely regulated output voltage at 12V
dc
. The output is fully
isolated from the input, allowing versatile polarity configurations and grounding connections. The modules exhibit high efficiency
of 90% typical at full load. Built-in filtering for both input and output minimizes the need for external filtering. The module is fully
self-protected with output over-current and over-voltage, over-temperature and input under voltage shutdown control. Optional
features include negative or positive on/off logic and SMT connections.
