Soft starter current ratings provide information on the soft starter's performance under defined operating conditions. If the operating conditions change, the soft starter's current rating must be recalculated. The software provides a fast and reliable interface for recalculating the soft starter rating to reflect the specific conditions of your application.
When selecting the soft starter model, it is vital to ensure the starter will not overheat during operation. When the soft starter SCRs are conducting current, they dissipate power and therefore generate heat. The soft starter must be able to dissipate all the heat generated, in order to operate safely. Larger model units have larger heatsinks and the SCRs are capable of conducting more current; this means that a larger unit can operate under more taxing conditions. Detailed information on the SCR and heatsink characteristics is built into the software.
To ensure safe and successful operation, the soft starter should be selected for the most severe operating conditions it will face.
