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 AC or DC auxiliary voltage is optionally available.
A green LED indicates POWER on. Start of monitoring function is delayed when power is switched on
-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
