SHG-PCH Variable Frequency Drive

Product Description

The explosion-proof variable frequency drive ШГ-ПЧ is designed for operation in hazardous areas to control pumping systems, ventilation units, drives for lifting mechanisms and conveyors.
The ШГ-ПЧ asynchronous electric motor variable frequency drive provides a smooth start, regulates speed, prevents inrush current surges, and protects against short circuits and overheating. The ШГ-ПЧ increases overall system efficiency, ensures long and reliable motor operation, minimizes maintenance and repair costs, and reduces energy consumption. The variable frequency drive type is selected based on the actual load power. If the device operates under a high load, a variable frequency drive with a higher power rating is required.

Advantages

  • Power up to 75 kW.
  • Vector control.
  • Complete set of encoder boards.
  • Wide choice of transmission protocols.
  • Quick torque setting when load changes.
  • High starting torque at low engine speeds.
  • Efficient heat dissipation system.
