Motor protection relay, DSP, VIP, Solid State Relay, SSR, WKS, SCR Unit
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
◆ Specific Advantage
►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 : 17ms or more
▸ Shut down delay time(SDDT):0(Instant)~10 sec
▸ Delay on make time(DOMT):1~30/60 sec
▸ trip output :1a,3A/Resistive
▸ Application environment/temperature
*operation/-20°C~60°C
*Storage/ -30°C~80 °C
*Humidity/30~85%,Relative/Non-condensing
▸ Time torrerence:±10%
▸ Insulation/case-Circuit: 10MOhm or more,/500VDC
▸ High voltage insulation:Case-Circuit/ 2KV,50/60Hz,1 min
▸ Contact-Contact:1KV,50/60Hz, 1 min
▸ Control power: 85~260VAC,50/60Hz(120~370VDC)
▸ Consuming power : 2VA/max
▸ Installation: 35mm DIN Rail,Panel Mounting
○ Critical Note:"ON" switch contact must be self-holding by auxiliary output of the contactor, This relay works when the time of 1 min has elapsed from the control power-ON("STP" is displayed to show normal operation is ready )
Specialized Point
*One Model Solution : Possible to connect with a contactor not limited by the positioned point of ON-OFF button
*When a commercial power is on again within 0(instant)~10 sec from power-off, this relay makes a motor to restart in the ordered schedule (1sec~60 sec)so that a power source transformer may not have an electrical starting shock
*If both preset for [SDDT:0] and [DODT:1sec] is done, this function is disable (One of both preset makes this function able)/This preset must be done under the control power is ON(LED:green),but not under operation state(LED:red)/The control power must be ON after OFF in order to preset this condition under the operation state
