The Littelfuse SSAC THC4160A is a solid-state single shot timer module for 120 V AC, with a 6 A solid-state output (60 A inrush). Its delay is fixed at 60 seconds, set at the factory.
A single shot built for fast-acting coin vending switches: a momentary closure of the initiate switch switches the load on for the set time; opening or reclosing the switch during timing has no effect. Drives motors, heaters and lamps directly.
Output: 1A SPST-NO, coin vending. Off-state leakage about 5 mA and voltage drop about 2.5 V at full load. Repeat accuracy: ±2% or 20 ms, whichever is greater. Setting accuracy: Factory calibration ±5%; ±10% over temperature and voltage. Reset time: 150 ms. Supply tolerance: ±15% of nominal; 50/60 Hz. Power: 2 VA.
It is surface mounted and has 0.250 in (6.3 mm) male quick-connect terminals. It operates from -20 to +60 °C and stores from -40 to +85 °C.
