Power Supply Units Types SD831 / 832 / 833 / 834- Description

ABB recommend the use of robust and reliable power supply units, (PSUs), for

providing power to the AC800 and S800I/O system, when connected to an industrial

mains network of installation category III. PSUs can be used for both non-redundant

and redundant applications.

The four PSUs are designed as switch mode power converters. They converting a.c.

or d.c. mains supply voltage to a regulated d.c. 24 V output. The four PSUs have

data as follows:

– SD831 = Input a.c. 100-240 V or d.c. 110-300 V.

Output d.c. 24 Volts regulated @ 3 A.

– SD832 = Input a.c. 100-120 or 200-240 V.

Output d.c. 24 Volts regulated @ 5 A

– SD833 = Input a.c. 100-120 or 200-240 V.

Output d.c. 24 Volts regulated @ 10 A

– SD834 = Input a.c. 100-240 V or d.c. 110-300 V.

Output d.c. 24 Volts regulated @ 20 A

The output voltage of the four PSUs is, as stated, a regulated, low noise, d.c. 24 V. A

LED, mounted on the PSU front panel indicates that the output voltage is within

range.

The PCS´s provide a soft start feature. The controlled power-on of a PSU therefore,

will not trip fuses or earth-fault circuit breakers. In addition, the normal

disturbances that occur within an industrial main network will not cause any

transient fault conditions or trips to occur.
