SITOP PSU100C 24 V/4 A stabilized power supply input: 120-230 V AC (110-300 V DC) output: 24 V DC/4 A *Ex approval no longer available* The SITOP compact single-phase power supplies are slim, space-saving power supplies for the low-end performance range. They are used for distributed applications in switchboxes or in small control cabinets. They are characterized by their low power loss over the entire load range. Losses are extremely low even in no-load operation, which is why these units are well-suited for efficient supply of machines and plants that are often in stand-by mode, for example. The switch-mode power supplies have a wide-range input for AC and DC power networks, with plug-in terminals that facilitate easy electrical connection. The wide temperature range and extensive certifications offer universal application possibilities. To further increase 24 V availability, the SITOP compact power supplies can be combined with redundancy modules and DC UPS Regardless of the industry or requirements, Siemens offers reliable and efficient power supplies for every plant.
