Hi everybody,

The SE2 series is a range of AC Drives, which are factory automation products used to control the speed of AC motors. The SE2 series features high performance sensorless vector control with auto-tuning function. This means the drive can adjust its control parameters automatically to achieve optimal motor performance.

The SE2 series has a high starting torque of 150%/1Hz and 200%/3Hz, and can output frequencies from 0.2Hz to 1000Hz. It also has high-precision static motor parameter auto-tuning function, excellent overload current rating of 200%/1s, and hardware protection design, including ground short circuit protection, output short circuit protection, and more.

The SE2 series has a built-in RS-485 communication interface and supports MODBUS-ASCII, MODBUS-RTU, and Shihlin communication protocol. It also has a built-in brake resistor, EMC input filter, and energy-saving function to realize power-saving control. Additionally, the SE2 series supports various expansion cards, such as I/O card, RS-485/422 card, 4-20mA power card, Profibus communication card, and DeviceNet communication card.

SE2 series has three different models: SE2021 for 1-phase 220V, SE2023 for 3-phase 220V, and SE2043 for 3-phase 440V.
