The OEM offices, workshop and warehouse will be closed for the Christmas period. See our full closing times and last order details.
CROUZET CONTROL
Control relay for phase monitoring with regeneration of voltage and asymmetry. Adjustable switch at the front for adjustment of correct voltage in 3-phase networks. Voltage switch's position is not registered until the operating voltage is switched on. If the switch position is changed during operation, all LEDs (LED indication) begin to flash but the unit will continue to function normally with the voltage that was set at the most recent power connection. The LEDs return to normal function when the correct voltage is restored. The relay monitors the correct phase sequence between the three phases or if any phase is lacking (measured U<0.7xUn), 70 % of the returned voltage. The asymmetry setting is made at the front between 5 and 15 % (the rated voltage between the phases Un x degree of asymmetry, %). In the event of an asymmetry fault, the relay triggers an alarm (drops out) after the time delay Tt that is set at the front by the user. Green LED (Un) indicates supply voltage OK. Yellow LED (R) indicates active relay output.
