Microprocessor-based control modules

Precision electronic control and the parameters monitoring together with the computing operations speed combined in the МХ150 and МХ250 microprocessor modules provide the ATS operation reliability and safety of the service personnel. All the ATS parameters' settings (time delays, switches' operation thresholds, etc.) are carried out without the ATS de-energizing and without opening the rack door. The microprocessor modules have the password protection against the unauthorized access to set-up menu.
