The AutoPC AD100 is a device used to handle the output parameters of a transformer rectifier according to its operating environment. It includes the following features:

• Simplified, intuitive man-machine interface using plain language.
• Constant U, I and constant potential basic functions.
• On/Off detection function with interruption and automatic latching of servo control.
• One 5 V 500 µA "On/Off" input accommodating any type of "On/Off" control equipment with live insertion safety.

The CHI 200 hour counter is used for recording the total correct operating time of a transformer rectifier and for the remote transmission of a mains fault and/or an "impressed current flow fault" alarm via two potential-free relays with normally closed contacts.

The CHE 200 hour counter is used for recording the total correct operating time of a cathodic protection system and for the remote transmission of a mains fault and/or an "impressed current flow fault" alarm via two potential-free relays with normally closed contacts.
