Definite time trip delays Triple relay operation gives moreflexibility Fast response analogue kVAr-signal output <50mS (F version) Wide range setting of high overload contact hysteresis Spcifications Auxiliary Voltage: Optional DC Auxiliary Voltage: 100-120,200-240,380-415 or 440-460VAC, 40-70Hz Nom. 12,24,48or110VDC Current Input: 1 or5AC.T.<0,1VA Contact rating: AC: 100VA-250V/2Amax. DC:50W-100V/1Amax. Adjustments Overload level 2: Overload level 1 : Trip level 0-100% of FSD 0-100%ofO/L2 Delay 0-30secs 0-30secs Hysteresis Overload level 2: Overload level 1 : 2-50% of FSD Fix 2% of FSD Analogue Output: *F version Up to 20mA, max 500R or Upto10V, min100kohm (other on request) Temperature: -20to+70°C Weight: 0.6kgs Front protection: | IP54 (IP65 optional) Application The digitally controlled KPVA19x range provides pr驩cision (1.0%) 2-step reactive power overload protection and monitoring of three phase generatorsormotors. The unit measures the voltage and current true r.m.s. value, and accuracy is independent of any wave form distortion. The auxiliary voltage issupplied from the unit voltage input. ADC auxiliary voltage input is optionallyavailable. A green LED indicates POWER on. Start of monitoring function is delayed when power is switched on (default 2 secs delay). In this way false tripping during power up is avoided. The DIN96 instrument reads the power level directly in kVAr. The kVAr-meter and the triple-zone status LEDsgives the clearsafety message: NORMAL/LEVEL1/LEVEL2ataglance. Relay Outputs The unit has relay outputs for overload level 1 (R1), Overload level 2 (R2) and R3 activates if either R1 or R2 is active. Overload 2 relay (R2) is fail to safety configured. A trip LED flashes when the trip level is passed, the relay trips when the delay has elapsed. The timer resets if the fault is removed during countdown. Hysteresis, Trip levels and delays are settable on unit rear. The unit meets IEC60092-504 and the relevant environmental and EMC tests specified in IEC60068/60092 and IEC61000/60533 respectively, to comply with the requirements of the major Classification Societies. Related information: The KPVA19x-range is also available for rail mounting as KCVA19x. Description KPVA191E For use in three phase 3 -wire configuration Both overload relays can be used for non-essential load release or as an alarm indication. A wide range overload contact hysteresis can be set to enable R2 to be used for a non-essential load to be reconnected or as a standby generator stop signal. Relay R3 is an additional relay that can be used for local indication, as an input to an alarm system etc. KPVA191F Similar to KPVA191E but also includes an analogue output proportional to the generator kVAr-load. KPVA194E For use in three phase 4-wire configuration Both overload relays can be used for non-essential load release or as an alarm indication. A wide range overload contact hysteresis can be set to enable R2 to be used for a non-essential load to be reconnected or as a standby generator stop signal. Relay R3 is an additional relay that can be used for local indication, as an input to an alarm system etc. KPVA194F Similar to KPVA194E but also includes an analogue output proportional to the generator kVAr-load. mCQQCOn Norway - UK
