INVT GD27 frequency converter: an industrial drive product with safety as its core
Safety is the lifeline of industrial production, and any safety accident may cause huge losses to enterprises. INVT always puts safety first in product design. The INVT GD27 flexible frequency converter integrates multiple advanced safety technologies, building a comprehensive safety protection system from hardware to software, providing solid safety guarantees for industrial production.

1. Built in STO function reaches SIL2 safety level
Safe Torque Stop (STO) is one of the most important safety functions in the industrial drive field, which can immediately cut off the torque output of the motor in emergency situations to prevent accidental movement of the equipment. The INVT GD27 EU model comes standard with STO function and meets the SIL2 level requirements of EN/IEC 61800-5-2. It adopts a redundant input design for higher reliability. When the safety switch is triggered, the STO function can take effect in a very short time, ensuring the safety of equipment and operators.

2. Comprehensive fault protection system to prevent various risks
INVT GD27 has comprehensive fault protection function, which can monitor the operation status of the frequency converter in real time, detect and handle various abnormal situations in a timely manner. The product provides various protections such as overcurrent, overvoltage, undervoltage, overtemperature, overload, phase loss, short circuit, etc. When a fault occurs, the frequency converter will immediately stop and display a fault code, making it convenient for operators to quickly troubleshoot and solve the problem. A comprehensive fault protection system can effectively prevent equipment damage and extend the service life of equipment.

3. Independent air duct design enhances operational reliability
Heat dissipation is one of the key factors affecting the reliability of frequency converters, and good heat dissipation design can ensure long-term stable operation of frequency converters. INVT GD27 adopts an independent air duct design, which separates the power devices and control circuits for heat dissipation, effectively avoiding the impact of heat on the control circuit. At the same time, the independent air duct design can prevent dust and debris from entering the interior of the frequency converter, maintain internal cleanliness, and improve the reliability of the product in harsh environments.

4. Strengthen the coating of the circuit board to resist harsh environments
The industrial production environment usually contains harmful substances such as dust, moisture, and corrosive gases, which can corrode the circuit board of the frequency converter and cause equipment failure. INVT GD27 adopts a reinforced circuit board coating design, covering a special protective coating on the surface of the circuit board, which can effectively isolate dust, moisture, and corrosive gases, protect the circuit board from corrosion, and greatly improve the product's adaptability and service life in harsh environments.
