Power Supply Units Types SD821/822/823 – Description
ABB recommends the use of these robust and reliable power supply units (PSUs)
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.
The three PSUs were 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
• SD822 = 24 Volts DC regulated @ 5 A
• SD821 = 24 Volts DC regulated @ 2.5 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.
A surge current limiter within the PSU circuit provides a soft-start feature.
Consequently the controlled power-on of a PSU will not trip fuses or ground-fault
circuit breakers. In addition, the normal disturbances that occur within an industrial
main network will not result in transient fault conditions or tripping.
This results in the surge current limiter effectively reducing the peak inrush current
caused by a power disruption, to a level the PSU can tolerate.
This soft-start, surge current limiter facility simplifies designing the system power
distribution circuits.
Insulation of Power Supply Units (PSU)
Basic with protective conductor; primary circuit separated from all other live
circuits by reinforced insulation.
Rated insulation voltage, Primary to Secondary 300 V AC.
