The QINT-781 3AXD5000019758 is an Inverter Board from ABB, designed to manage and control the operation
of industrial inverters in various automation and power control systems. This board is integral to systems that require
conversion between different types of electrical currents, such as alternating current (AC) and direct current (DC),
ensuring that power is supplied in the correct form and at optimal levels for connected equipment.
The QINT-781 is typically used in variable frequency drives (VFDs), motor control systems, and other power electronics
applications that require precise control over the power conversion and distribution process. It is specifically engineered
to handle the demanding conditions found in industrial environments, offering both reliability and high performance.
Power Conversion and Control: The QINT-781 inverter board efficiently converts and controls electrical power between AC and DC systems,
ensuring optimal energy supply for connected devices, such as motors and other power-intensive equipment.
Precise Inverter Control: Provides accurate control over the inverter’s operation, allowing for fine-tuned regulation of motor speeds, power flow,
and other critical parameters in motor-driven systems.
Efficient Performance: The board ensures high efficiency in power conversion, reducing energy loss and contributing to the overall energy
efficiency of the system.
Diagnostic and Protection Features: Built-in diagnostics for fault detection and protection, such as overcurrent, overvoltage, and short-circuit
protection, which safeguard the system from damage and ensure reliable operation.
Compact Design: The QINT-781 board is designed with a compact form factor, allowing for easy integration into existing inverter systems or
control panels without taking up excessive space.
Durable Construction: Constructed to withstand demanding industrial conditions, the board features a robust design capable of operating in
environments with high temperatures, vibrations, and electromagnetic disturbances.
