BENDER LINETRAXX ® VMD420 Three phase Voltage Frequency Monitor

Backup/Emergency Power Supply System Monitoring: Monitor the output voltage and frequency of backup power supply systems such as UPS power supply and diesel generators to ensure stable and reliable power supply after the backup power supply is started, ensuring the continuous operation of critical loads such as emergency lighting, fire equipment, and data centers.

Three phase motor protection: For equipment such as three-phase asynchronous motors, monitor the phase sequence, phase loss, and voltage asymmetry to prevent motor reversal due to phase sequence errors, or motor overheating or burnout due to phase loss or three-phase imbalance, thereby extending the service life of the motor.

Transformer protection: By monitoring the asymmetry of the secondary voltage of the transformer, identifying the asymmetric load state of the transformer, avoiding local overheating and increased losses caused by load imbalance, and ensuring the safe and stable operation of the transformer.

Portable load power supply monitoring: used for power supply circuits of portable loads such as mobile devices and temporary construction equipment, to monitor the stability of power supply voltage, timely detect power supply faults, and prevent equipment damage due to power supply problems in outdoor or temporary scenarios.
