ABB DPT160-CB011 R80 4P Automatic transfer switches dual power automatic

ABB DPT160-CB011 R80 4P transfer switch controller is a device for dual power switching. Its rated current and other parameters are different from those of the DPT250 model, but other functional features are similar. It has multiple protection functions and flexible control methods. The following is a detailed introduction:

Rated current: "160" in the model means that the frame current is 160A, and "R80" may mean that the overload protection current is 80A, which can meet the power supply requirements of the corresponding power load.

Number of poles: "4P" means that the transfer switch controller is four-pole, which can control three-phase live wires and one neutral wire at the same time, and is suitable for three-phase four-wire circuits.

Functional features: With a single-chip microcomputer as the control core, the hardware is simple and the reliability is high. It has short circuit and overload protection functions, as well as overvoltage, undervoltage, and phase loss automatic conversion functions and intelligent alarm functions.

Working mode: It can realize automatic transfer and automatic recovery, automatic transfer without automatic recovery and other working modes. That is, when the common power supply is normal, it is powered by the common power supply. When the common power supply fails, it is switched to the backup power supply. After the common power supply returns to normal, it can be determined whether to return to the common power supply according to the settings.

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

Protection level and application category: The protection level is IP20, which can prevent solid foreign objects larger than 12mm from entering, 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: The controller can set the common power return time (Tn), the backup power return time (Tr), and the common or backup switch to the double split position time (Ts). Users can set it according to actual needs to accurately control the timing of power switching.
