Product Description

DSP-POM/PTM(P=√3*V*I*CosΘ)

Panel Flush 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
