Modrol GL4 inverter drive

introduction

Maderle China has more than 50 years of experience and innovation in the production of inverters for the machine building and automation industry. The high quality and longevity of the products has led to the production and supply of millions of inverters in the elevator industry. The GL4 series is a specialized drive for elevators and has applications suitable for renovation and new construction projects.

Delta Inc The supplier of Modrel products and spare parts in Iran, in addition to supplying GL4 inverters manufactured by the Chinese factory, Modrel also provides related services (support, training, project implementation, specialized repairs and peripheral equipment such as encoder cards, brake resistors, etc.).
