SITOP modular plus 20 A Regulated power supply Input: 3 AC 400-500 V Output: DC 24 V/20 A Version with protective coating The 3-phase SITOP modular are technology power supplies for sophisticated solutions and offer maximum functionality for use in complex systems and machines. The input range enables connection to many networks around the world and ensures high levels of safety even with large voltage fluctuations. The power boost briefly supplies up to three times the rated current. In the event of an overload, you can choose between constant current or latching shutdown. The high efficiency keeps energy consumption and heat development in the control cabinet low and the compact metal housing also saves space. The version with the protective coating has improved resistance to extreme air pollution such as condensation, dust and ESD pollution, etc. To further increase the 24 V availability, the SITOP modular power supplies can be combined with buffer, DC UPS, redundancy and selectivity modules. No matter what industry, no matter what requirement - Siemens offers reliable and efficient power supplies for every system.
