Description
The KSTW002A5B series power modules are isolated DOSA compliant 1/16th brick dc-dc converters that operate over a wide
input voltage range of 36 Vdc -75Vdc and provide a single precisely regulated output voltage at 12Vdc. 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
