DSP-SDTR

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
