PBR-21 Non-Contact Reversing Starter is an electronic device designed for contactless control of actuators with single-phase electric motors equipped with an electromechanical brake. It is widely used in industrial automation systems, particularly in the energy, metallurgy, and chemical industries.

⚙️ Functional Features:

  • Contactless control: Ensures high reliability and long service life without mechanical contact wear.
  • Reversible operation: Allows changing the direction of motor rotation without additional mechanical components.
  • Built-in power supply: Simplifies connection and reduces the need for external power supply units.
  • Compact design and easy installation: Convenient for integration into existing systems.
  • Switching capacity: 220 V, 4 A (continuous operation duration no more than 100 seconds).
  • Power supply: Equipped with an internal power source for remote control of transistor switches.
