AFE adopts Infineon as the core inverter and adopts full digital control. It has high control precision, fast response speed, high precision, high reliability, programmable features and automatic two-way operation function.
The function of the energy feedback unit is to feed back the regenerative energy generated in the process of motor speed regulation to the power grid, so as to avoid the energy loss caused by the resistance heating of the conventional energy consumption braking unit, so as to achieve considerable energy saving effect. The product is mainly for motor testing, access to the DC bus in the test platform, power to the inverter, and has two-way energy conversion function.
The altitude shall not exceed 2000m (more than 2000m, derating is required). No medium with explosion risk, no gas or conductive medium that corrodes metal and damages insulation, no water vapor and serious mold are allowed
