The 8-pin plug type Power OFF Delay timers AT8PSN/AT8PMN Series are analog timers with simple configuration and direct recognition of time setting range. The analog timers are used to preserve circuits and restart during temporary power failures.

Main Features

  • Time setting range (AT8PSN : 0.05 to 10sec., AT8PMN : 0.05 to 10min.)
  • Simple time setup and direct read of time range
  • Power supply
    : 100-120VAC 50/60Hz, 200-240VAC 50/60Hz 100/110VDC, 24VAC 50/60Hz / 24VDC universal
  • Application : Protect circuit when momentary power failure and start it again
