The ABB NRED-61E is an industrial-grade inverter drive engineered for high-precision speed control, energy efficiency optimization, and reliable operation of AC induction motors—specifically optimized for applications requiring flexible motor 调速 (speed regulation), load adaptation, and seamless integration with industrial automation systems (e.g., fans, pumps, conveyors, and machine tools in manufacturing, water & wastewater, HVAC, and process industries). It functions as a "motor energy management hub," converting fixed AC input voltage/frequency to variable output to match motor speed with load demand, significantly reducing energy consumption (up to 40% for variable-load applications like pumps/fans) while protecting motors from overcurrent, overload, and voltage fluctuations. Designed to withstand harsh industrial conditions and comply with global efficiency standards (e.g., IE4), it balances performance, durability, and ease of use for mission-critical motor control systems. Below is its detailed specification:
