ABB UNS0881B-PV2 3BHE050077R0102 Power module

ABB UNS0881B-PV2 3BHE050077R0102 Power module

Feature
Provide stable DC power for each component of the UNITROL 1020 excitation system to ensure the normal operation of the system. It converts the input alternating current into direct current suitable for system use, and has voltage regulation and stabilization functions to meet the power needs under different load conditions.
With over current, over voltage, overheating and other protective functions, can automatically cut off the power supply or take appropriate protective measures in the event of abnormal conditions to prevent damage to the system, improve the reliability and stability of the entire excitation system.

Technical parameter
Input voltage: A variety of input voltage ranges are supported to adapt to different application scenarios and power grid conditions, such as AC 220V or AC 380V, depending on the actual configuration.
Output voltage: provides a stable DC output voltage for the excitation system, generally DC 24V or other specific DC voltage values, to meet the working voltage requirements of each module and equipment in the system.
Output current: It can provide a certain rated output current to meet the current requirements of the excitation system during normal operation and peak load. For example, the rated output current may range from several amps to tens of amps, depending on the specifications of the module.

Structural design
Compact modular design for easy installation and maintenance. The structural design takes into account the heat dissipation performance to ensure effective heat dissipation and maintain the normal operating temperature of the module during long operation. At the same time, the shell of the module usually has good electromagnetic compatibility, which can reduce the impact of electromagnetic interference on other equipment, and improve its own anti-interference ability.
