The product can be connected to an external controller to achieve speed regulation via 05V or 010V analog input, or 020 mA current signal input. Provides immediate shortcircuit protection when a fault occurs (shortcircuit protection). Maximum output frequency of the converter: 0400 Hz. Frequency converter with multifunction relay output, additional functional options, and a constantpressure water supply function. Fast response and a wide range for and low speeds. Internal protection features include under, over, overcurrent, and overheat protections, among others. Applications and use scenarios Conveyor and production line speed control: integrate with an external controller to adjust motor speed using 05V/010V analog or 020 mA input for precise belt or driven equipment speed on automated lines. Water supply systems requiring constant pressure: drive pumps to maintain stable pressure in building services, irrigation, or other closedloop water systems using the constantpressure water supply function. Ventilation and cooling applications: control fans or blowers in HVAC or industrial cooling setups with quick response to process changes and rapid speed adjustments.
