The SITOP power supply and its expansion modules are designed to provide stable and reliable power. Expansion modules like redundancy modules, buffer modules, and inrush current limiters enhance system availability and protection against various risks. Redundancy modules ensure continuous power even if one supply unit fails. Buffer modules provide short-term power during brief failures. Inrush current limiters reduce current surges during startup. These modules are designed for easy installation on standard mounting rails and feature simple commissioning.
