Enclosure Considerations for Soft Starter Panels
The choice of enclosure for soft starter panels depends heavily on the specific application. Key factors influencing the enclosure type include space availability, heat management, switching noise, electromagnetic interference (EMI), panel pressurization, and housing for digital components.
Soft starter and motor control panels typically generate more heat than others, necessitating efficient heat dissipation solutions. They also produce higher levels of EMI, which must be carefully managed, especially in environments where sensitive electronic equipment, like PLC panels, is used. In contrast, PLC panels emit less EMI and require less heat management. Selecting the proper enclosure ensures optimal equipment performance, safety, and longevity.
Purged Panels for Hazardous Environments
Purged panels are designed for use in hazardous areas with flammable gases or dust. To prevent contaminants from entering the enclosure, these panels are pressurized with air or an inert gas, maintaining a higher pressure inside the panel compared to the external environment. This positive pressure ensures that hazardous materials cannot infiltrate the enclosure.
Purged panels come equipped with built-in pressurization components. We rigorously test each panel for air leaks or pressure loss to guarantee reliable operation. Unlike other panels, purged panels do not typically include an air intake section. The amount of purging air or gas required is calculated based on the heat dissipation needs, ensuring the panel runs efficiently in your application.
EMI Reduction with Galvanized Mounting Plates
Our panels are constructed using galvanized mounting plates to minimize EMI-induced noise. The plates are expertly grounded to ensure superior electrical shielding and noise reduction.
Motor Control and Soft Starter Panels
Motor control and soft starter panels are standard ventilated enclosures where heat primarily originates from the load current and the switching components, such as thyristors and contactors. The thyristors manage voltage control, reducing inrush current during motor startup. Once the motor reaches full speed, bypass contactors engage, deactivating the thyristors. No additional filters are needed for CE-certified starters, whereas non-CE-certified starters may require extra filtering. Soft starter panels provide high efficiency, with minimal voltage drop across the thyristors, ensuring smooth and reliable operation.
