DSP-SDTR-P:Socket-Pin Type Digital Shut Down Turn-over Relay
Digital Shut Down Turn-over Relay
Main Feature
  •  DSP-SDTR :Shut Down Turn-over Relay
  • Socket-Pin Insatallation Type
  • Compact size, Complete Digital Type based on MCU    
  •  Just restart execution under instant power-off and voltage drop(Sag) 
  •  3 Wire Easy Connection : not concerend with ON-OFF  Switch Position     
    •  Possible to prest numerical operation time :3 Digit Window     
    • Shut down delay time/S-t
    • Delay on make time/d-t 
  • Applied benift
    • Just one model charges its job wothout concerning with ON-OFF switch position
    • Correct response for voltage drop, Zero Voltage
    • Neccessary minimum voltage duration time : 25ms or more
  • Critical Note
    • The contact of "ON" switch state must be self-holding by auxiliary output of the contactor
    • This relay needs to wait for 3 minitue at least under no-voltage state to change sequence control voltage
    • In case the sequence control power is on , then at first “v***”(version) is shown and nextly “actual voltage” is appeared. This means this relay has completed to remember a system voltage as a reference voltage, consequently this relay works after 1 min from an appearance of actual voltage
    • Once this relay remembers a reference voltage to be basis for an instant power-off state,then this reference voltage is indicated in motor stop state
    • Self-diagnostic test : press “CLR” key foe 3 sec or more in motor running state,then “tESt” is flickerd 3 times and and execute restarting once ” as showing “RUN” after “dt → “rUn”means that the restart is done
    • In order to reestablish a reference voltage, press both “UP” and “DN” key,then release them when “oPSEt” is shown
    • The minimum sustained time of the system voltage signal in order for this relay to do its job shall be 25mS or more
