1. Frequency converter with multi-function relay transmission, function, pressure watersupply function. 2. Short-circuit protection: when a short circuit occurs, the unit stops immediately. Maximum output frequency: 0-400 Hz. 3. Quick-stop response and wide speed range (high and low speeds). Internal protection functions include under-, over-, over-current, over-heat, and other protections. 4. External controller compatibility: can be connected to an external controller to realize speed regulation control via 0-5V/0-10V analog input and 0-20 mA current signal input. Benefits and key capabilities - Reliable short-circuit protection that stops the motor promptly, reducing equipment damage and downtime. - Broad speed range up to 0-400 Hz supports precise control for various applications. - Fast response with quick-stop capability and versatile speed options from high to low speeds. - Robust internal protections (under-, over-, over-current, over-heat, etc.) enhance safety and reliability in demanding environments. - Flexible control options: supports external control through standard 0-5V/0-10V analog inputs and 0-20 mA current input for easy integration with existing controllers. Attributes at a glance - Function: multi-function relay transmission with pressure watersupply function. - Compatibility: external controller capable via 0-5V/0-10V analog input and 0-20 mA current input. - Maximum output frequency: 0-400 Hz. - Protections: under-, over-, over-current, over-heat, and additional internal protections. - Performance: quick-stop response with high and low speed operation. Use scenarios - Conveyor systems in manufacturing: connect to an external controller to adjust belt speed precisely through 0-5V/0-10V or 0-20 mA signals, with fast stop on fault. - Water pumping and pressure-controlled installations: use the external control inputs to regulate pump speed for stable water pressure while benefiting from immediate short-circuit protection. - Packaging, textile, or processing equipment: leverage wide frequency range and rapid stop to achieve accurate motor control and safe shutdown during emergency conditions.
