Feature: 1. This is a simple vector inverter that can automatically increase the torsion moment 2. The product support PID automatic adjustment function, more convenient to use 3. Built-in protection functions, such as acceleration overvoltage, deceleration overvoltage, constant speed overvoltage, running undervoltage, acceleration overcurrent, deceleration overcurrent, uniform overcurrent, inverter overload, motor overload, CPU failure, etc. 4. Vector frequency converter come with simple operation and wiring, quick response to start and stop 5. Made of good-quality electronic components, stable and possess reliable performance Specification: Item Type: Vector Frequency Converter Material: ABS Control Method: V/F, vector Model AC input voltage Power Drive capacity(KVA) Output current(A) Applicable motor(KW) (KW) (heavy load/light load) (heavy load/light load) 100-3.7S2-1B 1‑Phase 220V 3.7 6.8 17/25 3.7/5.5 100-3.7T4-1B 3‑Phase 380V 3.7 6.8 8.5/12.5 3.7/5.5 100-5.5T4-1B 3‑Phase 380V 5.5 10 12.5/17.5 5.5/7.5 100-7.5T4-1B 3‑Phase 380V 7.5 14 17.5/24 7.5/11 . Package List: 1 x Vector Frequency Converter1 x Wire 1 x User Manual Note: 1. The ambient temperature is ‑5℃～40℃, avoid high temperature and humidity, and the 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 an environment containing flammable and explosive gases, liquids and solids.5. Do not install MCBs, contactors and related capacitors or varistors 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 source, and avoid sharing the same power source 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 non‑combustible materials such as iron plates to avoid damage to the inverter caused by vibration.9. When multiple inverters are installed in the same cabinet, when they are installed up and down, pay attention to the spacing and add a baffle in the middle.
