ABB Single Phase 24VDC Power Supply 0776 169 D H&B Contronic

Basic Information

The ABB Single Phase 24VDC Power Supply 0776 169 D H&B Contronic is a single-phase 24V DC power supply from ABB in conjunction with Hartmann&Braun. The part number 0776 169 D helps to identify it accurately in catalogues and system configurations.

Functional characteristics

Output characteristics:

It is capable of delivering a stable 24V DC output to provide reliable power to connected equipment. Stability of the output voltage is critical to ensure proper operation of the equipment, especially for electronic equipment that is sensitive to voltage fluctuations.

The power supply may have some overload protection and short circuit protection. In the event of an overload condition (e.g., when the power of the connected equipment exceeds the rated power of the power supply) or a short-circuit fault, it is capable of automatically taking protective measures, such as cutting off the output or limiting the current, in order to prevent damage to the power supply itself and to the connected equipment.

Input characteristics:

As a single-phase power supply, it can be connected to a single-phase AC power input. Its input voltage range may be flexible and able to adapt to a certain degree of grid voltage fluctuation, which allows it to work normally in different power environments.

Efficiency and Heat Dissipation:

Has a high power conversion efficiency, which means there is less energy loss in converting the incoming AC power to 24V DC. Meanwhile, in order to ensure stable operation for a long period of time, it may be equipped with an effective heat dissipation device, such as a heat sink or a small fan, in order to dissipate the heat generated during the working process.

Areas of application

Industrial Automation:

In industrial automation control systems, stable 24V DC power supplies are provided to various sensors, input/output modules of PLCs (programmable logic controllers), small relays, and other devices. These devices often require a precise and stable power supply to ensure the normal operation of their signal processing and control functions.

Communications equipment:

It can provide power support for some modules in communication equipment, such as small base station equipment, some control modules in communication cabinets, etc., to ensure stable transmission of communication signals and normal communication functions of the equipment.

Instrumentation:

It is used to provide 24V DC power supply for the electronic circuits in various instruments and meters, such as electronic oscilloscope, signal generator, etc., to ensure the accurate measurement and normal display function of the instruments and meters.

The AC 800F is available in two versions:  

• 4 MB static RAM, 4 MB EPROM  

• 16 MB synchronous dynamic RAM,   8 MB EPROM

The AC 800F optionally provides several levels  of redundancy: 

• device redundancy with 2 AC 800F  

• power supply redundancy (24 V DC)  

• Ethernet communication redundancy   (standard)  

• Cable redundancy for Profibus DP,   requires external equipment (RLM01)

AC 800F Controller Redundancy

Controller redundancy can be achieved by installing two  AC 800F. To ensure quick and smooth takeover by the secondary AC 800F in case the primary AC 800F fails, a dedicated  redundancy communications link through the second Ethernet  module makes sure that both AC 800F are always synchronized. All inputs and outputs are designed to support redundant  operation.
