SITOP Modular Power Supply The one, two and 3 phase SITOP modular units are the technology power supplies for demanding solutions. They offer maximum functionality for use in complex plants and machines. The wide-range input allows a connection to almost any electrical power system worldwide. The input ensures a high degree of safety even if there are large voltage fluctuations. They offer outstanding overload characteristics: Power boost delivers up to three-times the rated current for short periods of time. With extra power of 150%, loads with high power consumption can be connected without any problems. And if there is an overload, you can choose between constant current or automatic restart. The high efficiency keeps energy consumption and heat buildup in the control cabinet low, and the compact metal enclosure also saves space. To increase the 24 V availability, the SITOP smart power supplies can be combined with buffer, DC UPS, redundancy and selectivity modules.
