Heatsink (HS) option
Output Current Derating
Thermal resistance
The PKM2000E series DC/DC converters can be
ordered with a heatsink (HS) option . The heatsink
option have approximately 5 °C improved derating
compared with the PKM2000E without heatsink .
The HS option is intended to be mounted on a cold
wall to transfer heat away from the converter .
