Digital Motor Protection Relay

Installation: Panel Mounting Type

Model: DSP-SS1

​

 

Protection

 

• Over/Under current

• Locked Rotor

​

Auxiliary

• Self-diagnostics

​

Main Features

• MCU based digital control : optimized protection

• Compact size,Practical simple application

  • Protection : Over current/Under current, Phase Loss ,Locked rotor

    • Protection for Phase loss and Locked rotor is executed based on over current

  • Possible to check actual current and trip state based on LED indication

• 3 phase load protection through 2 CT

• To cover wide and precise current range for the protection

  • 10 Type

    • Definite T-I: 0.3A∼12A(0.3~6A for external CT)

    • Matched with external CT :1~600A, secondary rating of external CT is 5A

  • 60 Type

    • Definite T-I: 2A∼60A

• Trip cause indication by LED

  • Control power is loaded : Green

  • Normal operation : Red

  • Trip is happened : Yellow

• Convenient functional selection by DIP SW

  • N type : trip output(95-96,97-98) is energized in case control power is loaded

  • R type : trip output(95-96,97-98) is not energized in case control power is loaded

    • trip output is not responsed for selection of DIP SW in case normal operation is processed

  • RP ON : able state to protect reverse phase protection

  • RP OFF : disable state to protect reverse phase protection

• Reset after tripped

  • Manual : press “RESET” SW

  • Electrical : control power(A1-A2) off → possible to make remote control by power switch with remote distance

• Self-diagnostic function : “TEST” SW
