GE MAC1200 ECG EKG Machine Main Board Mother Board PCB Control CS_CI

GE MAC1200 ECG EKG Machine Main Board Mother Board PCB Control CS_CI in good working condition

►Brief Introduction

The PCB Control CS_CI is the mainboard of the MAC 1200, which has not all memory circuit mounted. The mainboard accommodates the control functions of the device, except the line power supply and the NC battery-charging controller.

► Generation of internal power supplies

• Logic power supply + 5V and + 3.3V

The processor core and the memory is a fully + 3.3V design.

The interface functions to display, to RS-232, to the printing unit and to the ECG acquisition unit are supplied with + 5V.

Both the + 3.3V and the + 5V are generated separately by a clock-rated voltage controller. By using the „adjustable version“ of the voltage controller, both supplies are based on the same voltage controller. The output voltage is determined by appropriate dimensioning of the voltage divider at the feedback input of the voltage controller.

• Standby supply + 5VSTB and + 3.3VSTB

The standby supply + 5VSTB supplies the ON/OFF Control, the + 3.3VSTB buffers the patient ECG memory when the device is turned off.

Both supplies are generated together from one low-power linear regulator with low quiescent supply current.

• Analog supply + 12V

+ 12V is used for the heating control and temperature monitoring of the printing unit, which requires only a current of a few milliamperes.

This supply is generated by a linear regulator with feedback input.
