DRP 7.0 digital current and voltage regulator for rectifiers
Country: Italy · Model: DRP 7.0
DRP 7.0 is a fully digital current and voltage regulator for rectifier systems in the chemical, mining and electrolysis industries. It works with a bridge or "double star" configuration on thyristors or on diodes with saturable reactors. The operator sees everything on a 4.3″ touchscreen HMI.
- Purpose

Description
The regulator was developed and made by the rectifier manufacturer itself. If the feedback or setpoint signal is lost, it instantly switches to a backup channel or smoothly reduces the current, so the process line does not get a sharp surge. The algorithm is built on cascaded voltage/current/angle loops, and PLL synchronization keeps it locked to the mains phase. For remote access there is Ethernet/Internet (IoT) and Windows software, through which support is provided remotely and firmware is updated. Old regulators on existing installations are replaced using the retrofit kit.
How to choose
The regulator is chosen by the rectifier topology, bridge or "double star", and by the type of valves, thyristors or diodes with saturable reactors. If an old regulator is installed, consider the retrofit kit, which makes it possible to keep the power section. For a new rectifier supplied together with regulation, look at the Rectifier Systems series. Separately, decide whether remote service is needed, since Ethernet/Internet (IoT) and the Windows program open up remote support and firmware updates.
