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.
Dielectric strength Basic with protective conductor. The primary circuit is separated from all other live circuits by reinforced insulation
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.
