Single Phase AC-AC SSR

Single Phase AC-AC SSR

  • Direct control by integrated circuits.
  • Normal open type.
  • Optically isolated.
  • Zero Voltage Turn-On, Zero Current Turn-off.
  • Random voltage turn-on for inductive load.
  • Built-in snubber.
  • High Dielectric Strength.
  • No noise feedback from output to input circuits.
  • No noise due to load current switching at nearzero.
  • Faster switching response.
  • Requires minimum actuation power.
  • Chassis mount.
(J: Zero voltage turn-on; K: Random turn-on)
