THE KR SERIES FROM WALL INDUSTRIES
The KR Series of DC/DC converters combines the attrac-
tive features of wide input voltage range, compact case
size, regulated and isolated, single or dual outputs. Triple
output protection of overload, overvoltage, and current limit-
ing makes the KR Series the ideal choice for a variety of
commercial PCB mount applications. Ultra-wide input volt-
age range available on some models.
SPECIFICATIONS: KR SERIES
All specifications apply @ +25 C ambient unless otherwise noted.
