ABB 1KGT031500R0001 - 520PSD01 Power Supply Unit

The ABB 1KGT031500R0001 is the order code for the 520PSD01 power supply unit (PSU) designed for the ABB RTU520 remote terminal unit line. Distributor catalogs consistently pair the two identifiers, and listings describe protective functions including overheat protection with thermal cut-off, overload, short-circuit and overvoltage protection, as expected for a PSU serving substation-grade RTU equipment. The 520PSD01 supplies the backplane power needed by RTU520 CPU and I/O modules, making it a critical spare for utility and industrial remote terminal installations. Input voltage range, output rails and power budget should be confirmed against your RTU520 configuration before ordering.
