Hospital Medical Parts Mindray PM9000 PM8000 PM7000 MEC1000 MEC2000 patient monitor power supply
► Brief Introduction
Power supply is an important part of the system, consisting of power board, backlight board, battery and fan.
The main power board converts the AC mains input into 5V and 12V DC to energize other parts of the system. Similarly LCD display requires particular supply, for which case a backlight board is supplied. The battery could maintain the formal function of the system for a short period when AC mains is disconnected. A small fan requiring DC input is used to realize superior ventilation.

► Schematic Diagram
► Introduction to Principle
This module converts 220V AC mains or battery power into 5V and 12V DC supplies to power other boards. If AC mains and battery coexist, the former take the priority to power the system and charge the latter at the same time.
1. AC/DC
Convert high-voltage AC supply into low-voltage DC supplies to power subsequent circuits and charge the battery.
2. Battery Control Circuit
If AC mains and battery coexist, this circuit controls the output from AC/DC part to charge the battery. If AC mains is disconnected, this circuit controls the battery to power the subsequent circuits.
3. 5V DC/DC
Convert the DC supply from the previous circuit into stable 5V DC supply to power other boards.
4. 12V DC/DC
Convert the DC supply from the previous circuit into stable 12V DC supply to power other boards.
5. Power Switch Circuit
Control the working status of 5V DC/DC and 12V DC/DC in order to control ON/OFF action of the patient monitor.
6. Voltage Detect Circuit
Detect the output voltages of various parts of the circuits; convert the analog signals into digital signals and send them into main board for further processing.
