KCW17x 3-PHASE GENERATOR REVERSE POWER AND OVERLOAD GUARD • Precision Generator kW Load Protection, not affected by heavily distorted waveforms • Total processing time less than 50mS • 3 or 4-wire systems. Definite time trip delays • 2-level overload protection (F version) • Optional fast analogue kW-signal output, <50mS • Wide range setting of overload contact hysteresis • Optional DIN96 Slave Indicator with status LEDs Application Specifications Monitored Voltage: Optional Separate Auxiliary Voltage DC: 100-120V, 200-240V, 380-415V, 440-460 or 480VAC 40-70Hz (Fuse 0,5A) 24, 48 or 110VDC (Fuse 2A) (Add nr 2 for models with separate aux. supply. ex: KCW171C2) Current Input: Contact rating: 1 or 5A C.T. <0,1VA AC: 100VA - 250V/2A max. DC: 50W - 100V/1A max. Adjustments available: Depending of selected model (see page 3 and 4) Analogue outputs: Up to 20mA, max 500ohm Up to 10VDC, min 100kohm (other outputs available on request) Temperature: -20 to +70ºC Weight: 0.6kgs Front protection: IP21 The digital controlled KCW17x range provides precision (1.0%) reverse power and overload protection and monitoring of three phase generators. Available for 3-phase 3-wire (2W3) and 4-wire (3W4) systems. The unit measures the voltage and current true r.m.s. value, and accuracy is independent of any wave form distortion. As standard the auxiliary voltage is taken from the unit monitored voltage input. A separate DC auxiliary voltage is optionally available. 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 DIN-rail mounted instrument reads the power level directly in kW. The optional slave watt-meter and the triple-zone status LEDs at a glance gives the clear safety message: - OVERLOAD - NORMAL - REVERSE POWER 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. RELAY OUTPUTS Relay operation depends on the selected model. Other combinations are available on request. OUTPUTS If output is used for remote meter reading, we recommend 0-1mAfor the slave indicator. Related information: The KCW17x-range is also available for rail mounting as KPW17x.
