The Littelfuse SSAC KSDS1110SP is a solid-state single shot timer module for 12 V DC, with a 1 A solid-state output (10 A inrush). Its delay is fixed at 10 seconds, set at the factory.
Input voltage must be applied before and during timing. A momentary or maintained closure of the initiate switch (leading-edge triggered) energizes the output for the set time; opening or reclosing the switch during timing has no effect. The output will not energize if the switch is closed when input voltage is applied. It resets when the delay is complete and the switch is open; loss of input voltage resets the delay and the output. For dispensing, exposure timing and pulse shaping.
Output: 1A SPST-NO, positive switching. Voltage drop about 1.7 V at full load. Repeat accuracy: ±0.5%. Setting accuracy: Factory calibration ±10%; ±10% over temperature and voltage. Reset time: 150 ms. Supply tolerance: ±20% of nominal; 50/60 Hz.
It is surface mounted and has 0.250 in (6.3 mm) male quick-connect terminals. It operates from -40 to +60 °C and stores from -40 to +85 °C.
