PS12 Series High Performance Solid State Relays AC solid state relay for loads up to 10A @ 250Vrms Product Facts I Approved to DSCC drawing 86031. I Optically coupled all solid state relay. I TTL compatible input. I Zero voltage turn-on for low EMI. I Custom power package with screw terminals. The PS12 series solid state relay is designed for AC power switching up to 10 amps at 250Vrms. The circuit employs back-to-back SCRs with zero voltage turn-on for reliable switch- ing of resistive or reactive loads. TTL compatible input circuitry is optically isolated to 1,500Vrms from the AC load circuit. The relay is offered in two versions: the PS12-1Y with “Y” level screening per Mil-R28750C, and the PS12-1W screened per Tyco Electronics specifications for CII relays, equivalent to former “W” level of Mil-R28750.

Operation at elevated load currents up to 10 amps is dependent on the use of suitable heatsink to limit junction temperature. 2. Heating of output chips during and after a surge may cause loss of output blocking capability until junction temperature falls below maximum rating. 3. Internal snubber network is provided across output chips. 2 Figure 2 - Load Current vs. Temperature 1°C/W HEAT SINK 1000 Load Current (Amps rms) Peak Surge Current, Non-Repetitive (% of Rated Current) Figure 1 - Peak Surge Current vs. Surge Current Duration 800 600 400 200 0 10 10 8 6 NO HEAT SINK 4 2 0 100 1000 Surge Current Duration (mSec) 10,000 20 30 40 50 60 70 80 90 100 110 120 Ambient Temperature (°C) PS12-TBD–PDF–KRG–10-09 . www.tycoelectronics.com Dimensions are in inches and millimeters unless otherwise specified.
