Description

TVR2000-4 for three-phase 415v AC power among the features: over voltage protection / phase protection / Stagger Protection / voltage unbalance protection Selection and Ordering data 1, TVR2000 Department of standard products, high sensitivity for a better environment; TVR2000Z heavy-duty product line, slightly lower sensitivity for In heavy machinery. (Slightly lower sensitivity refers to the over-voltage, voltage imbalances is slightly lower)

Fives. Typical applications     1, according to a wiring diagram, press ON when the power supply is normal to start, stop pressing OFF; when the power failure will automatically cut off to protect the motor.     2, according to the wiring diagram 2, when the power supply is normal to start, when the power failure will automatically cut off to protect the motor contactor normally open contact NC contact PLC digital input       With the controller chain protection.         3. Exhibit 3 wiring, when the power supply fault relay output off signal to the PLC, controlled by the controller protection.
