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.

DC-OK relay contact (SD834 only)
This feature monitors the output voltage, which is produced by the power supply
itself. It is independent of a backfed voltage from a unit that is connected in parallel
to the power supply output.
Short dips will be extended to a signal length of 250ms. Dips shorter than 1ms will
be ignored.
Contact closes: for output voltage > 90% of the adjusted output voltage.
Contact opens: for output voltage dips > 10% below the adjusted output voltage.
Contact ratings: max 60Vdc 0.3A, 30Vdc 1A, 30Vac 0.5A resistive load
Min. >1mA, >5 V over open contact.
Isolation voltage:Field test: a.c. 2000 V to input. a.c. 500 V to output.

Fuses and Protective Devices
Recommended primary external fuse:
Table 114. SD834 Schematic and Instructions for parallel use.
Schematic for parallel operation Instructions for parallel use
a) Only SD834 can be used in parallel connection.
b) Adjust the output voltages of all power supplies to
approximately the same value (±500mV). Otherwise,
the DC-OK signal might not work properly.
c) A fuse (or diode) on the output is only required if
more than three units are connected in parallel.
d) Do not continuously load the terminals with more
than 25A. Keep an installation clearance of 15mm
(left/right) between two power supplies and avoid
installing the power supplies on top of each other.
