Used-good ECG parts Comen CM1200B ECG power management board CM1200B_POWER_B CEP3CCB 00377

■ Product Describe

The Comen CM1200B ECG Power Management Board is a genuine accessory for the CM1200B ECG, a key component tailored to the complex power requirements of the device. It precisely converts, regulates, and distributes power from an external power source or internal battery, ensuring a stable and optimal power supply to each functional module, ensuring reliable operation and accurate ECG monitoring.

This accessory is only compatible with the Comen CM1200B ECG, a multi-lead, simultaneous ECG device widely used in medical institutions at all levels. It can be used in outpatient clinics, emergency rooms, and wards to quickly and accurately monitor cardiac function. It supports 12-lead simultaneous ECG signal acquisition and features automatic analysis, quickly identifying common arrhythmias and annotating the results on the printed ECG report, assisting doctors in diagnosis and improving efficiency.

■ Product features

1. Multiple Power Input Adapter

The accessory supports two power input options: an external AC 220V power source and a built-in rechargeable lithium battery. When connected to an external power source, the power management board automatically switches the power supply to the mains and intelligently manages the charging of the internal battery. Conversely, when the external power source is disconnected, it automatically switches to the internal battery, ensuring continuous operation and data monitoring.

2. Precise Voltage Conversion

The power management board features voltage conversion circuitry that converts AC 220V mains power into different DC voltage levels to meet the power requirements of different modules in the device.

3. Power Distribution and Load Balancing

Power is rationally distributed to each functional module of the ECG machine, dynamically adjusting the power supply based on each module's real-time power requirements.

4. Circuit Protection

Multiple built-in protection circuits monitor power input and output in real time.​

■ FAQ​

Q1: If the ECG machine suddenly fails to power on, is it related to the power management board?

A1: First, check whether the external power connection is normal. If everything is normal, the device's inability to power on may be due to a problem with the power management board. Contact a professional repair technician for repair.

Q2: During use, the ECG machine experiences abnormal electromagnetic interference. Is this related to the power management board?

A2: There is a certain correlation. A fault in the power management board, such as a failure in the filter circuit, may prevent the effective removal of clutter interference from the mains, thereby affecting ECG signal acquisition and generating abnormal electromagnetic interference.

Q3: How do I determine if the power management board needs to be replaced?

A3: If the device frequently shuts down automatically, fails to power on despite normal external power, detects abnormal power output voltage (deviations exceeding ±0.5% from the standard value), or experiences severe electromagnetic interference that is determined to be caused by the power supply, the power management board is likely faulty. Replacing the power management board is recommended.
