DOLD speed and phase control modules, available from ELTRON, are specialised devices designed to monitor the operating parameters of electric motors in industrial automation systems. Their task is to detect irregularities such as phase failure, phase sequence error, overspeed or unauthorised speed drop.
This category includes, among others:
These devices guarantee greater reliability of drive systems, protect against machine damage and enable full integration with the control system. The available versions differ in module width (from 53 to 168 mm), control type and power range.
Application: transport systems, HVAC, fans, pumps, production machines and other installations requiring motor condition monitoring.
