Performance characteristics:

1. EMC performance improvement

• EMC has a built-in safety capacitor, and can be equipped with an external capacitor group and a simple filter. The optional Schaffner filter can reach the C2 international standard.
• The special grounding pile design is used to facilitate grounding and weaken electromagnetic interference. It is more suitable for high-interference occasions.

2. Meet multiple certification standards

• The product complies with the directive requirements of the EU "New Method for Technical Coordination and Standardization". EMC directive 2004/108/EC Electromagnetic Compatibility Directive and LVD Directive 2006/95/EC Low Voltage Directive IEC61000-2-2:2002, IEC61000-4-2:2008, IEC61000-4-3:2008, EN61800-5-1:2007, etc.
• "Meets the RoHS directive"

3. Excellent air duct design

• The entire series has independent air duct design, and the heat dissipation duct is separated from the electrical and electronic circuits to reduce the failure rate of the electronic circuit part
• The fan adopts an easy-to-disassemble design for easy installation and maintenance

4. Leading motor drive technology

No PG vector control, PG vector control, and V control meet the process requirements of different loads. Advanced vector control algorithms can achieve high-performance current vector control of induction asynchronous motors and permanent magnet synchronous motors.

5. Perfect communication function design and performance improvement
Built-in isolated RS485 communication design, external expansion of CANopen, PROFIBUS-DP (up to PP05), profinet, etc., to meet the needs of different communication occasions

6. Instantaneous stop restart function
When the power grid drops or loses power instantly, the inverter can run without stopping by feeding back energy within the effective time, which is especially suitable for occasions with high requirements for equipment operation continuity

7. Multiple keyboard human-computerinteraction

• LED single display, LED dual display, potentiometer,film button, silicone button, LCD display and smartbacklight (optional)
• Film button (suitable for high protection requirements)
