Benefits from the Use

1. stable operation at increased rates of THU network non-linearity up to 40%
2. use of tubular electric heaters
3. reduction of equipment downtime during maintenance
4. a possibility of remote control via Modbus RTU Protocol
5. unification when replacing obsolete models PNTT (thyristor voltage rectifier) and PNTTE (thyristor voltage rectifier with natural cooling)

Advantages

• • forced air-cooling of power assemblies
  • quick replacement of thyristor modules (up to 12 minutes)
  • operation at the ambient temperatures up to +60°C
  • easy access to major units and components
  • control system with adjustable user settings
  • functions of self-testing and monitoring of operation load (short circuits, open circuits, excess of operating current, etc.)
  • work with diagrams of power supply: “star without N”, “star with N”, triangle, 1, 2 or 3 phase loads
