Feature: 1. Simple Setting: With built in industry professional macro application, supports external keyboard and one key industry parameter setting. 2. Safe Protection: Enabling 3 phase current detection as well as short to ground detection, this VFD can offer secure protection for motor. 3. Flexible Usage: Widely applied woodworking machinery, CNC machine tool, textile machinery, ceramic machinery, stone machinery and so on. 4. Easy to Install: The mobile phone screen structure has largely reduced the volume, which needs smaller space for much easier installation. 5. Reliable Using: Premium PCB with coating ensures stable working, and the DC fan also promises efficient heat dissipation for durability. Specification: Item Type: Variable Frequency Drive Product Material: ABS Circuit Board Material: PCB Product Model: CM800-4T1R5B Input Voltage: AC 380-440V (3 phase voltage) Output Voltage: 0-440V Power: 1.5KW Current: 3.8A Control Mode: Open loop vector control. Speed Stabilization Accuracy: ±0.2% Environment Temperature: -10~50℃ Speed Adjustment Range: 1:200 Application Scenarios: Used in woodworking machinery, CNC machine tool, textile machinery, ceramic machinery, stone machinery and other industries. . Package List: 1 x Variable Frequency Drive Note: 1. Ambient temperature ‑5℃～40℃, avoid high temperature and humidity, humidity is less than 90% (no condensation). 2. Prevent electromagnetic interference and stay away from the source of interference. 3. Prevent the intrusion of water droplets, steam, dust, cotton wool, and fine metal powder, and prevent the intrusion of oil, salt, and corrosive gases. 4. It is forbidden to install in the environment containing flammable and explosive gas, liquid and solid. 5. Do not install air switch, contact and related capacitors or varistor on the output side, otherwise it will cause the inverter to malfunction, trip protection or damage components.6. The inverter must use an independent power supply, and avoid sharing the same power supply with electric welders, otherwise it will cause protection or damage to the inverter.7. In order to facilitate cooling and maintenance, the inverter must be installed vertically with enough space around to ensure smooth air circulation.8. The installation wall should be made of incombustible materials such as iron plates, and vibrations must be avoided so as not to cause damage to the inverter.9. When multiple inverters are installed in the same cabinet, and when they are installed up and down, pay attention to the spacing and add a diversion baffle in the middle.
