The Siemens 3RX9513-0AA00 is a robust power supply unit designed to facilitate the smooth operation of AS-Interface systems. This unit is particularly adept at providing a stabilized direct voltage of 30 V DC, ensuring safety extra-low voltage (PELV/SELV) with high constancy and minimal residual ripple. The output voltage is floating and boasts resistance to short-circuits and no-load operation, which significantly enhances its reliability in various industrial settings.
Crafted for durability, the power supply unit comes with an IP20 degree of protection and is classified as safety class I. It is a primary switched-mode power supply that can be connected to a single-phase AC system with a rated voltage of 120/230 V AC at 50/60 Hz, making it versatile for global industrial applications.
The unit's automatic restart feature after a short-circuit or overload is a testament to its self-reliant operational capability. It is designed for snap-on mounting on a horizontal standard mounting rail, ensuring ease of installation and maintenance. With a compact footprint, the device measures 70 mm in width, 125 mm in height, and 125 mm in depth, allowing for efficient use of space within control cabinets.
The Siemens 3RX9513-0AA00 is also equipped with a signalling contact that indicates the presence of an output voltage greater than 26.5 V DC, providing users with immediate visual feedback on the operational status of the unit. This power supply is an essential component for those seeking a reliable and efficient power source for their AS-Interface system requirements.
