Using dynamic current limiting (DCL) technology, the ProTop power supply triggers circuit breakers and powerful motors and can address the needs of high-end power supply systems. It can be used in applications with extreme vibration and temperature conditions or in applications in which space saving for redundant power supply systems is required. This industrial power supply has redundancy O-rings already integrated, providing the capability to work in redundancy with other powers supplies without need of redundancy modules. It reduces potential failure points, saves space and increases installation performance.
