ABB SD823 3BSC610039R1 Power supply unit
Description:
SD823 is ABB 800xA control system power supply unit. ABB recommends the use of these robust and reliable power supply units (PSUs) ,SD823, for providing power to the AC 800M Controller when connected to an industrial mains network of installation category III. All three PSUs can be used for both nonredundant and redundant applications. 
SD823 is designed as switch mode power converters, converting AC mains supply voltage to a regulated 24V DC output. Rated output capacity:  SD823 = 24 Volts DC regulated @ 10 A.
The mains input voltage is set to either 115 or 230 V by means of a switch mounted on the face of the unit. The factory default position for this switch is 230 V.
The output voltage of all three PSUs is a regulated, low noise, 24 V DC. A green LED on the PSU front panel indicates that the output circuit is providing the correct output voltage level. The double connectors provided on the 24 V DC output terminals allow for connecting more than one piece of equipment.
