ABOUT DRP 7.0

Drp 7.0

FRIEM Industrial Design

The DRP 7.0 is designed for industrial applications and especially to satisfy the operation and protection requirements for the chemical and mining electrolysis industries beyond all applications requiring high direct current.

Dedicated to

Customers looking for a state-of-the-art technology for rectifiers regulation. Suitable for brand new rectifiers and retrofit of old units.

Innovative and intuitive

The DRP 7.0 has been designed by FRIEM’s R&D engineers to improve the overall functionalities of the rectifier.

Continuous improvement

The numbering 7.0 stands for the seventh FRIEM’s digital regulator and for the 70 years of the company activity.

IMPROVEMENTS

bullet2 Specific for rectifiers

A single control board manages bridge or double star converter topologies with thyristor or diode with saturable reactors.

 

bullet2 User-friendly interface

Simple to be used and easy to set up,  with a dedicated HMI  graphic 4.3”  touch screen.

 

bullet2 Suitable for revamping

Thanks to a retrofit kit designed for a fast and simple replacement of the old regulator.

 

bullet2 Bespoke management software

A dedicated SW tool (MS Windows platform) allows remote support, assistance and firmware upgrade.

bullet2 IoT connectivity

All the measures can be easily shared over Ethernet/Internet, and stored for data visualization/analysis.

 

bullet2 Advanced control loop management

Cascade structure (Voltage/Current/Angle Loop) with reference/limitation signals always accessible and adjustable at runtime.

 

bullet2 Innovative grid synchronization

PLL algorithm for precise grid angle detection also in presence of voltage harmonics.

 

bullet2 Smart feedback fault management

with instantaneous switch to a secondary feedback signal or trip with controlled angle ramp down.

New features to improve the performances of your rectifiers

bullet1 To operate

with latest generation of electrolysers in Chlor-Alkali and Hydrogen plants:

  • High stability and accuracy 0.1% full scale
  • High speed for polarization rectifiers

 

bullet1 To revamp

and upgrade high current rectifiers equipped with obsolete digital regulators:

  • DRP 7.0 is fully interchangeable with the previous digital regulators DRP-6T
  • DRP 7.0 is fully compatible with all other Brands of rectifiers

 

 

 

bullet1 To satisfy

the operation and protection requirements in metal refining and electrowinning plants

  • Fast reaction and response time 1/6 of the period
  • Different customizable functions and safety features

 

bullet1 To comply

with heavy industrial conditions typical of high current plants such as aluminium smelters, graphitization furnaces and DC arc furnaces:

  • Highest immunity against electromagnetic fields
  • Coating and finishing to protect the board from the surrounding corrosive and dusty environment

The excellence of DRP 7.0

Astonishing technical performances thanks to a continuous improvement concept

Flexible

The new DRP 7.0 has a very flexible architecture in all its functions. It can be customized to fit the most demanding processes in terms of speed and stability of DC current and voltage, and fine-tuned during the lifecycle of the plants.

Easy to upgrade

The DRP 7.0 is equipped with spare hardware and software inputs and outputs, beyond a customizable firmware structure, thus it can be upgraded with new functions without changing the hardware.
