CZF-BT-TRMS phase sequence and phase loss sensor /T2UK

Parameters:

• CN: 85364900
• PKWiU: 27/12/24.0
• Voltage measurement range [V] up to: 400
• Width [mm]: 35
• Maximum allowed time delay in the event of a power failure [s]: 5
• Minimum adjustable time delay at power failure [s]: 0.5000
• Phase unbalance control: Yes
• Phase loss control: Yes
• Phase sequence control: No

With adjustable response time. 1NO/NC contact. The CKF-BT-TrueRMS phase sequence and loss sensor is designed to protect electric motors powered from a three-phase network. The phase sequence and loss sensor will operate in the event of voltage loss in at least one phase or when there is voltage asymmetry between the phases. That is, when there is a risk of engine destruction. CKF-BT-TrueRMS also controls the sequence of power phases, preventing the motor from spinning in the wrong direction. Operation Voltage loss in at least one phase or voltage asymmetry between phases above the activation threshold will turn off the engine. The shutdown will occur with a set delay, which prevents accidental disconnection of the motor during a momentary voltage drop. It will be switched on again automatically when the voltage increases by 5 V above the activation voltage (i.e. by the voltage hysteresis value). With the above anomalies, it is impossible to start the engine. If the sequence of phases in front of the sensor is changed, causing an undesirable change in the direction of rotation of the motor, the sensor will not allow the motor to start. Reconnection is possible after the correct phase sequence is restored. By measuring the true effective voltage value (TrueRMS), the sensor guarantees correct operation even when operating in a heavily disturbed power supply network.

(Price for 1 Pcs)
