KSPD SERIES
Solid State Timer
Description
The KSPD Series is a factory programmed module available
with 1 of 12 standard dual functions. The time delays can be
factory fixed, externally or onboard adjustable, or a combination
of fixed and adjustable. The 1A steady, 10A inrush rated
solid-state output provides 100 million operations, typical. Its
microcontroller timing circuit provides excellent repeat accuracy
and stability. Encapsulation protects against shock, vibration,
and humidity. The KSPD Series is a cost effective approach for
OEM applications that require small size and long life.
