Recommended regular maintenance
The thyristor power controller requires very little maintenance if installed in an appropriate environment.
Regular inspection according to the maintenance schedule is strongly recommended. Preventive maintenance
prevents unexpected production stop and production loss. It also increases availability of the thyristor power
controller.
The environmental and operating conditions of the thyristor power controller are also to be considered.
A harsh environment, such as high ambient temperature, humidity, dust and cyclic heavy load, not only
shortens the components lifetime but also the preventive maintenance and replacement intervals.
