The Littelfuse SSAC HRDS12A3 is a single shot timer for 12 V DC, with non-isolated SPDT relay contacts rated 30 A (NO) / 15 A (NC) resistive at 125/240 V AC. Its delay is adjustable from 0.1 to 10 minutes with its onboard knob.
Input voltage must be applied before and during timing. A momentary or maintained closure of the initiate switch energizes the output relay for the set time; opening or reclosing the switch during timing has no effect.
Output: 1C SPDT relay, 30 A (NO) / 15 A (NC) resistive at 125/240 V AC; 20 A / 10 A at 28 V DC; NO 1 hp at 125 V AC, 2 hp at 240 V AC (non-isolated contacts), tolerance ±1%. Repeat accuracy: ±0.5% or 20 ms, whichever is greater. Setting accuracy: Factory calibration ±1%; ±2% over temperature and voltage. Reset time: 150 ms. Supply tolerance: -15% / +20% of nominal. Power: 2 W. Life: 1,000,000 operations mechanical, 100,000 electrical.
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.
