Data Sheets

Portable, 3-phase industrial vacuums that are supplied with power through a plug may not start when the phase sequence is incorrect or a phase has failed.
If a phase fails during operation, the vacuum should switch off.

Solution description

The voltage monitor detects the phase sequence and phase failure, while monitoring the asymmetry detects the failure of a phase.
Even when reverse voltage is generated when the motor continues to run on two phases.

Benefit/added value

– The compact size with a width of only 17.5 mm saves space for mobile applications
