ABB DPT250-CB011 R100 3P Automatic transfer switches dual power automatic

ABB DPT250-CB011 R100 3P transfer switch controller is a device for dual power switching. The following is its related introduction:

Basic parameters: "250" means the frame current is 250A, "R100" means the rated current is 100A, and "3P" represents three poles, which can be used to control three-phase live wires.

Control core and function: With a single-chip microcomputer as the control core, the hardware is simple and reliable. It has short circuit and overload protection functions, and can also realize overvoltage, undervoltage, and phase loss automatic conversion and intelligent alarm functions, which can effectively ensure the safety of circuits and loads.

Working mode and position: Supports automatic resetting and automatic resetting working modes. There are usually three stable working positions, namely, normal power on, backup power off; normal power off, backup power on; normal power off, backup power off.

Operation mode: It can automatically switch with load, and can also be manually switched by the handle in an emergency. And there is an interlock between the manual and automatic operation modes, and manual operation is not possible in the automatic state, which improves the safety of use.

Protection level and application environment: The protection level is generally IP20, which can prevent solid foreign objects larger than 12mm from entering, and is suitable for general indoor environments. The installation site is usually not more than 2000m above sea level, the ambient air temperature is generally -25℃ to 55℃, the relative humidity is less than 95%, and the pollution level is III.

Application category: The application category is AC-33B, which is suitable for controlling related circuits such as motor loads.

Time setting function: The normal power return time (Tn), the backup power return time (Tr), and the normal or backup switching to the double split position time (Ts) can be set. Users can accurately set the power switching time according to actual needs.

Compliance with standards: Comply with relevant standards such as IEC60947-6-1:1998 (version 1.2) and GB14048.11-2002 to ensure that product quality and performance meet industry specifications.
