DOLD multifunctional motor controllers are modern devices designed for comprehensive management of three-phase motors in industrial applications. They combine the functions of reversing contactors, soft start systems and safety systems, ensuring full control over the direction of rotation, load and operating parameters of the drive.
The range includes models with active power control, temperature monitoring and a two-state trigger function. Thanks to their compact design and DIN rail mounting option, these controllers are ideal for switchboards and control cabinets.
The BH 9253, BH 9255, BI 9254 and UG 9256 series devices are used, among others, in machine automation systems, fans, pumps and wherever precise control and protection of drive systems is required.
