  Module Compatibility	- Supported Modules: ABB P-HA-RPS-12050 (12V/50A), P-HA-RPS-2425 (24V/25A), P-HA-RPS-4812 (48V/12A) - Module Interface: Hot-swap compatible (no power interruption during replacement) - Parallel Operation: Supports up to 3 modules in parallel (for current sharing)	Wide module compatibility covers common DC voltages (12V/24V/48V) for diverse loads (e.g., 24V for PLCs, 48V for industrial Ethernet switches); parallel operation increases total output current

• Electrical & Protection Specifications:

  Parameter	Details	Performance Metrics
  Input/Output Ratings	- Input Voltage: 100V~240V AC (single-phase, 50/60Hz) - Total Output Current: Up to 75A (3×25A modules); up to 50A (1×50A + 2×0A redundant) - Output Voltage Range: Dependent on installed modules (12V/24V/48V DC, ±2% regulation) - Current Sharing Accuracy: ±5% (for parallel modules)	Wide input voltage range suits global electrical systems; high total output current (75A) supports high-density automation racks (e.g., 20+ PLCs + 10 HMs)
  Protection Features	- Module-Level: Overcurrent (120% rated current, latching), overvoltage (115% rated voltage, shutdown), short-circuit (instantaneous, self-recovery) - Chassis-Level: Over-temperature (fan failure/ambient >55℃, alarm), input under-voltage (≤85V AC, alarm), reverse polarity (input, fuse protection) - Fault Indicators: LED per module (normal/fault), chassis LED (power/overtemp/fan fault)	Multi-layer protection prevents damage to modules and connected loads; self-recovery short-circuit protection reduces manual intervention

• Environmental & Monitoring Specifications:

  Parameter	Details	Performance Metrics
  Environmental Ratings	- Operating Temperature Range: 0℃~+55℃ (32℉~131℉); +55℃~+60℃ with 10% derating - Storage Temperature Range: -20℃~+70℃ (-4℉~158℉) - Humidity Tolerance: 5%~95% RH (non-condensing, 40℃) - Vibration Resistance: 10~500Hz, 0.5g acceleration (IEC 60068-2-6) - Shock Resistance: 20g (11ms half-sine, IEC 60068-2-27) - EMC Compliance: EN 61000-6-2 (immunity: Level 3); EN 61000-6-3 (emission: Class B)	Wide temperature range suits unconditioned industrial spaces; Level 3 EMC immunity resists interference from VFDs, motors, and power transients
  Monitoring & Signals	- Status Outputs: 2 dry contact relays (global fault, module redundancy loss) - Monitoring Interface: Optional RS485 (Modbus RTU) via expansion card (for remote current/voltage/temperature monitoring) - Local Indicators: 3 module LEDs (green=normal, red=fault), 3 chassis LEDs (power/overtemp/fan fault)	Dry contact relays integrate with PLC/SCADA for fault alerts; optional Modbus support enables remote power management (e.g., data center BMS)

• Compliance Standards: CE, UL 60950-1, IEC 61558-2-1, RoHS, ISO 9001 |

2. Core Features

• Modular & Scalable Design: 3 hot-swap module slots—supports flexible power scaling (e.g., adding a 24V module for new PLCs) and N+1 redundancy (e.g., 2 active modules + 1 standby) to maximize system availability, critical for uptime-dependent applications (e.g., data centers).
• 19-Inch Rack-Mount Compatibility: 3U height fits standard 19-inch industrial racks—enables centralized power distribution alongside other rack-mounted equipment (e.g., servers, switches, control units), simplifying cabinet layout and cable management.
• Redundant Cooling: Dual front-to-back airflow fans—ensures consistent cooling of modules even if one fan fails; front intake/back exhaust design aligns with industrial rack thermal management best practices, preventing hot air recirculation.
• Comprehensive Protection: Multi-level protection (overcurrent, overvoltage, overtemp) at both module and chassis levels—safeguards against electrical faults (e.g., short-circuited load, input voltage spikes) and environmental stress (e.g., fan failure), reducing downtime.
• Hot-Swap Capability: Modules can be replaced without powering down the chassis—enables maintenance or module upgrades (e.g., replacing a 12V module with a 24V module) without interrupting power to critical loads (e.g., process control systems).
• Global Input Compatibility: 100V~240V AC input—adapts to diverse electrical systems (e.g., 110V AC in North America, 230V AC in Europe), eliminating the need for voltage transformers and simplifying global deployment.
• Status Monitoring: Local LEDs and dry contact relays—provide real-time visibility of power system health (e.g., module fault, fan failure); dry contacts integrate with PLC/SCADA to trigger remote alarms, enabling proactive maintenance.

3. Application Fields

• Industrial Automation Racks: Control System Power Distribution:
  • Process Automation Racks: Powers 24V DC PLCs, HMIs, and sensors in oil/gas or chemical process racks—N+1 redundancy ensures no power interruption during module failure; hot-swap enables maintenance without stopping production.
  • Automotive Assembly Line Controls: Distributes 12V/24V power to robotic controllers and vision systems—high total output current (75A) supports dense component layouts; EMC immunity resists interference from welding robots.
• Data Centers & IT Infrastructure: Server & Network Power:
  • Edge Data Centers: Powers 48V DC servers and 24V network switches—19-inch rack mount fits IT cabinets; redundant cooling ensures stable operation in high-density server environments.
  • Industrial Data Loggers: Supplies 24V power to data acquisition systems (DAS)—wide temperature range (0℃~+55℃) suits unconditioned server rooms; Modbus monitoring (optional) tracks power consumption for energy optimization.
• Critical Infrastructure: Reliable Power for Essential Systems:
  • Water Treatment Plants: Powers 24V DC pump controllers and SCADA systems—redundant configuration prevents power loss during module maintenance; short-circuit protection safeguards against wiring faults in wet environments.
  • Transportation Control Systems: Supplies 12V/24V power to railway signaling or traffic management systems—shock/vibration resistance withstands infrastructure vibrations; overtemp protection ensures operation in outdoor enclosures.
• Medical & Laboratory Equipment: Stable Power for Precision Devices:
  • Laboratory Automation Racks: Powers 24V DC analytical instruments and sample handlers—±2% output voltage regulation ensures measurement accuracy; redundant power minimizes data loss from unexpected shutdowns.
  • Medical Imaging Auxiliaries: Supplies 48V power to MRI/CT scanner cooling systems—UL 60950-1 compliance meets medical safety standards; hot-swap enables maintenance without disrupting patient care.
