GE Dash1800 Patient Monitor GEHC-IT UI LEFT BOARD ( Power Switch
Board) 2037646-001 2037729-001
■ Product Describe
GE Dash1800 Patient Monitor GEHC-IT UI LEFT BOARD (Power Switch
Board) 2037646-001 2037729-001 is the original power switch control
board of GE Dash1800 patient monitor and one of the core components
of the monitor power supply system.
It has many important functions, mainly for the management of the
monitor power on and off control, feedback of power supply status
and overcurrent protection of the battery.
The service life of the power switch board is designed to be 5-10
years, and its key components are designed according to this
service life; the mechanical life of the relay can reach more than
100,000 on-off operations. If the machine is turned on and off once
a day, it can be used for about 270 years (actually affected by the
load current, the relay life in medical equipment is usually
estimated to be 5-8 years).
■ Product Advantages
1. Modular design
The multi-layer PCB board welded by surface mount technology (SMT)
integrates key components such as power management chip (PMIC),
relays, fuses, status indicators, etc., and is suitable for
embedded installation on the left operation panel of Dash1800.
2. Anti-accidental touch
The external insulation protection cover prevents medical staff
from accidentally touching the high-voltage circuit; the buttons
are made of medical-grade silicone material, which is resistant to
disinfection and corrosion and can withstand more than 100,000
press tests
3. Low-cost maintenance
Modular replacement: No need to disassemble the entire monitor,
only 4 cross screws need to be removed to replace the power switch
board, and the average maintenance time is ≤15 minutes.
Preventive maintenance: Support online firmware upgrades, and the
PMIC control program can be updated through GE engineer-specific
tools to optimize power efficiency.
4. Environmental adaptability
Anti-electromagnetic interference: The PCB board is wrapped with a
copper foil shielding layer, which can resist ±15kV electrostatic
discharge (ESD) and 10V/m radio frequency interference, ensuring
stable operation in strong interference environments such as MRI
rooms.
Dust and moisture proof: IPX5 protection level, can withstand 30°
angle water spray test, and adapt to complex environments such as
operating rooms and ICUs.

■ FAQ
Q: How to determine whether the power switch board is faulty?
A: If the monitor screen displays "power module abnormality" or the
power indicator light is off, you can use a multimeter to check
whether the output voltage is normal.
Q: Can a third-party power switch board be used as a substitute?
A: It is not recommended to use a third-party power switch control
board as a substitute. Compatibility is not guaranteed and the lack
of medical safety certification may cause equipment failure or data
loss.
Q: How long is the warranty period for the power switch board?
A: This is a used original accessory. We give the accessory a
90-day warranty.
