KSPUA8C - KSPUA Counter Series

Littelfuse Counters
The KSPU Series is a factory programmed module available in any 1 of 14 standard functions. The KSPU offers a single adjustable counter function. Switch adjustment allows accurate selection of the number of counts the first time and every time. 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 KSPU Series is a cost effective approach for OEM applications that require small size, solid state reliability, and accurate switch adjustment.
