DSP-POL/PTL(P=√3*V*I*CosΘ)
Panel Mounting Type/Voltage-Current based digital motor protection relay
* MCU based digital protection : possible for precised operation
*To have a gurantee for authorized operator : Password
* To replace easily existing model which is not apply for Logic Input : Main trip/1c(95-96- 98), Aux/1c(05-06-08)
*Compact size, Multi-function/ : Over/Under Load[Current],Over/Under voltage, Phase loss, Reverse phase,Locked rotor,Shock(stall),Ground fault
*Indication : Voltage, Load[KW]/Curr. , KWH, Earth current, AWT[Accumulated Working Time],Power Factor,Load Factor
*To show a trip cause and an information of the operation in character and/or number : 5 Digit Window
* To cover a wide current range for the protection
*10 Type:0.5∼10A/0.37[KW] ∼7.5[KW](3P 480V ),0.1[KW]∼2.2[KW](1P 220V)
*70 Type:5A ∼ 70A/3.7[KW] ∼ 52[KW](3P 480V),1[kw]∼15[KW](1P 220V)
*Rotated indication for operating factor in every 3 sec during working :V,KW/Curr, KWH, Ec,AWT,Pf,Lf
*High sensitive level and wide zero phase current range for ground fault protection : 30mA ∼ 2A
*Basic type : External ZCT/200mA/1.5mA,Optional type : Embeded ZCT
*Various way for the reset : Manual or Automatic/to response for wide application in installed sequence system
*To keep a stable operation under frequency variation from Inverter : 20Hz ∼ 400Hz
*Self-diagonostic test by one touch for "SET" key
*Alarm befor making trip by over load/current
*To memorize latest 8 trip among trip events
