Drager 5703141 DC power_supply Draeger 5703141 Carina AC-DC power supply board

The Dräger 5703141 Power Supply Board is a precision-engineered printed circuit board assembly designed specifically for the Dräger Carina sub-acute care ventilator, serving as the central power management and distribution component within the device's electronic assembly. This OEM-specification board performs critical AC-to-DC power conversion, transforming universal mains input (100–240 V, 50/60 Hz) into the regulated low-voltage DC supplies required by the Carina's turbine drive, control electronics, display module, and monitoring subsystems. The board incorporates sophisticated power management circuitry supporting the Carina's multi-source power architecture—including mains power supply, internal battery operation, and optional external battery (12–24 V DC) connection—with seamless automatic switransfer between power sources to ensure uninterrupted ventilation. Built to Dräger's stringent medical electronics standards, the 5703141 features comprehensive protection circuitry against over-voltage, over-current, and thermal overload conditions, while managing the internal battery charging system that delivers up to 60 minutes of standalone operation. This field-replaceable PCB enables biomedical engineering teams to restore Carina ventilators experiencing power-related failures to full operational capability.

Description of ventilator parts:

This power supply board is extensively deployed across Sub-Acute Care Wards, Intermediate Care Units, Home Ventilation Programs, Long-Term Care Facilities, Emergency Departments, and Intrahospital Transport scenarios where Dräger Carina ventilators provide turbine-driven non-invasive and invasive ventilation for adult and pediatric patients. It serves as a critical field-replaceable spare part for biomedical engineering teams, enabling rapid repair of Carina devices experiencing power failures, battery charging malfunctions, complete device shutdown, or electrical faults during preventive maintenance. The board's multi-source power architecture is particularly valuable in home care and transport environments where reliable battery operation and flexible power input are essential for continuous patient ventilation. Its universal mains input compatibility (100–240 V) supports deployment across diverse global healthcare facilities and home settings with varying electrical infrastructure standards.

Advantage:

The 5703141 power supply board distinguishes itself through its multi-source power management architecture, seamlessly coordinating mains power, internal battery, and optional external battery (12–24 V DC) operation with automatic source switching that guarantees uninterrupted ventilation during power transitions. Its universal mains input range (100–240 V, 50/60 Hz) enables global deployment without voltage-specific configuration, while the efficient power conversion design maintains low typical power consumption (35 W), minimizing heat generation and maximizing internal battery runtime. The board's integrated battery charging management continuously maintains the internal battery at optimal charge levels, delivering up to 60 minutes of standalone operation for transport and emergency scenarios. Additionally, its comprehensive protection circuitry safeguards both the board itself and connected subsystems against over-voltage, over-current, and thermal overload conditions, protecting the turbine drive and control electronics from electrical faults. The OEM-standardized design ensures precise electrical and mechanical compatibility with the Carina's electronic assembly, facilitating straightforward field replacement during service interventions
