Voltage and Current constant rectifier is a compact and robust switch mode power supply (SMPS), forced cooled, specifically designed for Cathodic protection. Standard SCADA RS485 MODBUS fieldbus.
The rectifier can be parameterized by the AM software RS485 or USB-B, and optionally parameterized using three push buttons by menu structure. The parameters can be protected by a PIN code to prevent unauthorized personnel to change settings.
Features
- Supply: 190V…230V.
- Modbus over RS485.
