Hardware Specifications

ABB Backplane Bus Infrastructure & Power Density

The SA610 3BHT300019R1 module feeds regulated 24 VDC current directly into the AC110/160 system backplane bus, driving subrack card slots and internal logic processors. The power unit incorporates internal high-frequency switching architecture operating at greater than 90% efficiency, suppressing thermal dissipation while maintaining deterministic voltage regulation under full 10 A load steps. Backplane voltage stability is buffered against supply transients, preventing voltage drops across I/O module communication logic and controller sub-buses.

Field Installation Guidelines

• Subrack Placement: Align the SA610 module with the dedicated power supply slot of the AC110/160 subrack. Slide the unit along the chassis guide rails until the rear high-current connector locks into the backplane motherboard.
• AC/DC Input Cabling: Wire line, neutral, and protective earth conductors using stranded copper wire rated for 300 V / 105 deg C (minimum AWG 14). Torque terminal retention screws to 0.6 N m.
• Grounding Requirements: Secure a direct low-impedance bond between the subrack chassis earth terminal and the main ground bus, ensuring a earth bond resistance below 0.1 Ohm.
• Thermal Clearances: Ensure unimpeded vertical forced-air airflow across the top and bottom ventilation grilles of the subrack assembly to maintain operation across the -25 to +70 deg C thermal envelope.

Frequently Asked Questions

• Does the SA610 power supply permit hot-swapping during active backplane operation?

  No. Main AC/DC primary supply lines must be isolated before inserting or removing the SA610 module to prevent backplane connector arcing and bus transients.

• What input supply sources are supported by the primary terminals?

  The unit accepts wide-range AC inputs from 85 to 264 VAC (47 to 63 Hz) and DC inputs from 100 to 370 VDC without physical jumper configuration.

• How is output voltage regulation maintained across varying current loads?

  Internal feedback circuits hold the output at 24 VDC within a +/-1% typical tolerance band across the entire 0 to 10 A continuous output current range.

• What output ripple voltage is present on the 24 VDC system rail?

  Output voltage ripple and switching noise are filtered to under 1% peak-to-peak relative to the 24 VDC nominal output rail.

• What protection mechanisms trigger during an overcurrent event on the output?

  The internal power circuit implements current limiting to restrict output power to its 240 W max ceiling, automatically recovering upon fault removal.

• What is the recommended grounding conductor size for the power supply rack?

  Use a copper grounding conductor of at least 2.5 mm2 (AWG 12) connected directly to the subrack functional protective earth terminal.

• What storage environment limits apply to spare SA610 power modules?

  Modules must be stored in unpowered packaging within an ambient temperature range of -40 to +85 deg C and relative humidity under 95% non-condensing.

• Does the power supply require forced-air fan cooling inside the panel cabinet?

  Natural convection cooling is supported up to full rated output provided a 100 mm clear vertical space is maintained above and below the card cage.
