Description
ABB BDPS-11C (3AXD50000042965)
- Technical Specifications:
- Input: 85–264 V AC (47–63 Hz) or 120–370 V DC (depending on exact variant)
- Output: 24 V DC (typical 5 A–10 A depending on load rating) and/or 5 V DC for backplane
- Ripple & Noise: <50 mV peak-to-peak
- Efficiency: Typically >85%
- Overload Protection: Auto-reset on overload removal
- Operating Temp.: 0 °C to +60 °C
- Mounting: Plug-in to dedicated PSU slot in Advant rack or DIN rail adapter
- Indicators: Power-OK LED
- Functional Features:
- Short-circuit and overload protection with auto-recovery
- Redundant operation possible with parallel-capable units (diode-OR)
- Wide input voltage tolerance for global site compatibility
- Application Scenarios:
- Powers Advant OCS CPU, communication processors, and I/O modules
- Backup or primary supply in process DCS cabinets
- Retrofit/replacement in existing ABB rack installations
- Material & Structure:
- Metal chassis with vent slots for convection cooling
- Connectors: Screw terminals or blade contacts engaging rack backplane
- Working Principle:
AC input is rectified and filtered, then switched through a high-frequency PWM converter. The secondary-side is transformer-isolated and regulated by a feedback loop maintaining constant DC output voltage despite load or input variations.
- Installation Requirements:
- Verify input voltage selector/jumper matches site mains before connection
- Ensure proper earth grounding of rack chassis
- Leave adequate clearance above/below for convection airflow
- Precautions:
- Never connect AC and DC input simultaneously
- Confirm total rack current draw does not exceed PSU rated output
- Disconnect mains before removing or inserting the module
