GE CARESCAPE B650 Patient Monitor AC Power Supply PN MINT1180A1575K02 With 90days Warranty

The GE CARESCAPE B650 patient monitor features a sophisticated power management subsystem engineered for maximum reliability and patient safety. The system comprises an internal AC/DC power supply unit, a DC/DC board for power distribution, and an optional backup battery.

The core component of the AC power system is an internal, medical-grade switched-mode power supply with the following specifications:

For uninterrupted monitoring during patient transport or power outages, the B650 supports an optional rechargeable lithium-ion battery:

• Voltage: 11.1V lithium-ion battery
• Capacity: 6.21 Ah typical capacity
• Runtime: Approximately 1-2 hours when fully charged (varies by configuration)
• Charging Time: 2-3 hours to reach full charge

The DC/DC board manages power from both the AC/DC supply and battery, providing several critical functions:

• Voltage Conversion: Converts incoming power to required voltages (+3.3V for CPU board, +5V for interface boards, +12V for display backlight and optional recorder)
• Power Path Management: Intelligently selects between AC power and battery power for seamless switching during power loss
• Battery Management: Handles all battery charging and communication through a Power Management Controller (PMC) to optimize charging and monitor battery status

The entire power system is designed for high efficiency and uses convection cooling, with the power supply unit's heat sink mounted to the aluminum rear case for effective heat dissipation without requiring a fan.
