Weidmuller PROtop High-End Power Supplies
Weidmuller PROtop High-End Power Supplies are designed for any environment and are fit for digitalization. These PROtop power supplies combine high efficiency with a compact, durable design and direct parallel connection, eliminating the need for diode modules. This results in reduced cabinet space, lower system costs, and provides a streamlined solution for demanding industrial applications and preventive maintenance. An optional communication module enables seamless integration into higher-level control systems, delivering real-time condition monitoring, remote diagnostics, and control capabilities. This provides early insight into performance deviations, helping to optimize system uptime and prevent unplanned downtime.
With continuous access to process data and status information, PROtop becomes a fully networked component, empowering faster troubleshooting, predictive maintenance, and more efficient system management across operations. Integrated ORing MOSFETs increase power density while eliminating the need for additional assembly and wiring, thereby minimizing installation effort. In parallel operation, efficient current sharing and long-term stability are ensured.
Dynamic current limiting (DCL) technology delivers high pulse reserves for demanding loads, enabling reliable circuit breaker tripping and smooth motor starts. Weidmuller PROtop High-End Power Supplies provide up to 300% power for 100ms and 150% for up to 5s when needed. With their robust construction and advanced energy-reserve capabilities, PROtop power supplies deliver consistent, dependable power, even in the most challenging industrial environments.
