SITOP Smart Power Supply Unit The 1 and 3 phase SITOP smart is the universal and powerful standard power supply for machinery and plant engineering. Despite their compact design, they offer an excellent overload response. Thanks to a power boost of 150%, loads with high power consumption can be connected without any problems. The permanent overload capability of 120% offers power reserves in-case of expansions. The high degree of efficiency results in low energy consumption and minimal heat generation inside the control cabinet. To increase the 24 V availability, the SITOP smart power supply can be combined with buffer, DC UPS, redundancy and selectivity modules. Features and Benefits • Compact design • Extra power with 1.5 times the rated current for brief functional overload • Permanent overload capability with 1.2 times the rated current up to 45°C (24 V versions) • High degree of efficiency up to 91.5% • Adjustable output voltage for compensating voltage drops • Signalling contact for easy integration in the plant monitoring system • Wide temperature range from -25°C or -10°C to 70°C Approvals cULus cCSAus ATEX IECEx GL
