VLCU-3D-SPAU Vacuum Level Control Unit for Three-Phase Vacuum Pumps

The VLCU-3D-SPAU vacuum level control unit with automatic Start / Stop function is designed to control the operation of vacuum pumps equipped with three-phase motors 3Ph 400 V, 50 Hz. Depending on the version, the unit supports an output current from 2.5 A to 10 A.

The control unit is equipped with integrated motor protection and is suitable for vacuum systems where automatic vacuum maintenance is required. It switches the vacuum pump on and off according to the preset vacuum level, helping to reduce pump running time, improve energy efficiency and maintain stable vacuum conditions during operation.

Vacuum control is based on a Festo SPAU series V1R pressure sensor. The sensor features a backlit digital display, which makes setup and monitoring easy. The current vacuum level is shown directly on the display, and the required vacuum value is maintained automatically.
