Cathodic Protection Products - Concrete

ICCP Amstel 1 N Concrete

Range 2V  1 to 10A <100W


The Amstel 1 Type C is a compact and robust switch mode power supply, forced cooled, specifically designed for cathodic protection in concrete structures. Standard SCADA RS485 MODBUS fieldbus.


The Amstel Rectifier is Voltage and Current constant. 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.







  • Supply: 190V...230V.
