Power Supply for Dash2000

GE Dash2000 Patient Monitor Power Supply Module 850-954M-D - OEM Replacement Part

► Brief Description

The GE Dash2000, a high-quality device suitable for use in emergency rooms, intensive care units, and general wards, employs a dual power supply solution of "AC adapter power + intelligent battery system" to ensure continuity of clinical use and ease of transport. This internal power module is a crucial component of the power supply system, converting externally input unregulated DC power into multiple precision DC outputs and providing overvoltage, overcurrent protection, and undervoltage monitoring to ensure stable system operation.

► More Details

The core functions of the power supply board of the GE Dash2000 monitor are AC-DC conversion, voltage isolation, and providing voltage regulation and protection. The main output voltages are as follows:

1. +5V: Powers the device's main microprocessor, digital logic circuits, memory, and other core digital components. This is the system's "heart" power supply.

2. ±5V (or ±8V): Powers the analog front-end circuits (such as amplifiers and filters for ECG, respiration, and body temperature modules), requiring low noise and high stability.

3. ±12V (or ±15V): Powers some operational amplifiers, sensors, or backlight inverters for the display screen, and other components requiring higher voltages.

4. +3.3V: Powers some low-power chips.

5. +24V: Used to drive high-power peripheral components such as printer motors or air pumps.
