ABB DPT250-CB011 R250 4P Automatic transfer switches dual power automatic

ABB DPT250-CB011 R250 4P transfer switch controller is a dual power conversion device with superior performance. In addition to the related content mentioned above, here is more information about it:

Working mode: It can realize automatic transfer and automatic recovery, automatic transfer without automatic recovery and other working modes. In the automatic transfer and automatic recovery mode, the normal power supply is used when the normal power supply is normal, and the normal power supply is switched to the backup power supply when the normal power supply fails. After the normal power supply returns to normal, it returns to the normal power supply; in the automatic transfer without automatic recovery mode, after the normal power supply returns to normal, the switch does not return to the normal power supply.

Protection function: It has electromechanical interlocking protection to ensure that the switch works reliably and does not interfere with each other. For the power grid-to-power generation switch, the generator "over/underfrequency" protection function can also be added, which has a wider range of use.

Operation mode: It can automatically switch with load, and can also be manually switched by handle in an emergency. And there is an interlock between manual and automatic operation modes to ensure that manual operation is not allowed in automatic conditions, which improves safety.

Technical standards: Comply with IEC60947-6-1:1998 (version 1.2) low-voltage switchgear and control equipment Part VI automatic transfer switchgear and GB14048.11-2002 low-voltage switchgear and control equipment automatic transfer switchgear and other standards.

Protection level and application category: The protection level is IP20, which can prevent the entry of solid foreign objects larger than 12mm and can meet the requirements of general indoor environment use. The application category is AC-33B, which is suitable for controlling related circuits such as motor loads.

Time setting function: There are three time settings in the controller settings, namely the normal power return time (Tn), the backup power return time (Tr), and the normal or backup switch to the double split position time (Ts). Users can set according to actual needs to accurately control the timing of power switching.
