The Littelfuse SSAC FS127-100 is a solid-state flasher for 120 V AC, with a 2 A halfwave rectified AC output (10 A inrush). It flashes at a fixed 100 flashes per minute (±20%), a custom rate set at the factory. It flashes incandescent and resistive loads.
Upon application of input voltage the OFF time begins; at the end of it the load energizes for the ON time, then de-energizes, and the cycle repeats until input voltage is removed. Removing input voltage resets the output and the sequence to the OFF time.
Sequence: OFF first, ≈ 50% on. Supply tolerance: ±15% of nominal; 50/60 Hz. Other fixed rates: 45 to 150 FPM ±20%, to order.
It is surface mounted on a removable bracket with one #8 (M4) screw and has 18 AWG wire leads, 6" (15.2 cm). Dimensions: 1.5" H x 0.94" W (38.1 x 23.9 mm). It operates from -20 to +60 °C and stores from -40 to +85 °C.
