SMART Series Small Size Variable Frequency Drive
To satisfy requirements from industrial automation industries, our company has launched the next-generation variable frequency drive, namely the SMART series VFD. The state of the art VFD houses inside optimized hardware and software while offering 2 control modes: the scalar V/F control and vector control. Excellent drive performance comes from high reliability, adjustability, and integrated controls. Typical applications for this small-sized variable frequency drive are in the food packaging, textile, and machinery industries.
We at Easydrive Electric understand that different industries may require varied power control functionalities. That is why we have offer OEM and ODM services which allow your desired variable frequency drive customized here. Simply tell us your VFD specifications, and we can provide an integrated solution just for you.
Features of Variable Frequency Drive
1. Power input terminals
With the input lead on top and the output lead on bottom, the wiring of this VFD is pretty simple. Flame-retardant, reinforced ABS is selected to make the VFD body.
2. Powerful Functions
Built PID, simplified PLC system, and 8 preset speeds. Integrated Modbus485 serial bus, double control modes (vector control and scalar V/F control), and built-in braking circuit.
3. Remote Control Port
The remote control port supports standard RS-485 communications. It comes with an extend cable which allows the keyboard to be connected to the port at a distance. 8-pin network cable provides easy access to the internet.
4. Unique Structure
The air flue is separated from the drive control module. The capacitor is mounted onto the air channel but is insulated from it. The IPM, or intelligent power module for short, provides an easy way to cool the VFD components.
5. Multifunction Keypad
Turn the knob of the keypad clockwise to increase the inverter drive's frequency. The keypad comes with an LED display, and supports remote network control. Frequency control accuracy: 0.01Hz
6. Overall Reliability
The variable frequency drive is certified by the EMC testing lab. It has been also approved in the electrical inspection conducted by China National Center for Quality Supervision and Test of Electrical Control and Distribution Equipment.
