Feature: 1. Low noise: The carrier frequency is continuously adjustable from 1.0KHz to 16.0KHz, which minimizes motor noise. 2. Automatic voltage regulation: according to the needs of dynamic voltage regulation, static voltage regulation, no voltage regulation three ways 3. Low frequency and high torsion: the starting torsion hits twice the rated torsion within 50Hz constant torsion output 4. 16-segment programmable multi-speed control multiple operating modes are optional 5. Can set up to 16 speeds automatically run each section of the running time can be set 6. A variety of communication protocols can be selected with linkage synchronization control 7. Wide range, low frequency mode, 0-300Hz; high frequency mode: 0-3000Hz 8. Widely used in constant pressure water supply, wind pressure constant pressure control and other occasion Specification: Item Type: Vector Frequency Converter Model: SKI600-045G/055P-4 Adapted Motor Power: 45KW Input: AC 3PH 380V±15% 90A 47-63Hz Output: AC 3PH 0-380V 90A 0Hz-3000Hz Filter: Built-In Filter Output Voltage Regulation Mode: PWM Control Control Method: Current Vector Application Range: Universal Size: Approx. 565 x 320 x 275mm / 22.2 x 12.6 x 10.8in Panel Opening Size: Approx. 90 x 130mm / 3.5 x 5.1in Installation Size: Approx. 240 x 537mm / 9.4 x 21.1in Three Major Performances: 1.
