Mindray T8 Patient Monitor Power Switch Board 6800-20-50089
Mindray T8 Patient Monitor Power Switch Board Brief Introduction
The power board is a functional circuit used in electronic equipment to convert the input power voltage (such as industrial frequency 220V) into various levels of working voltage (such as 12V-, 15V-) required by the electronic circuit. Putting these on one board can It's called a power strip. However, the power switch is a type of power conversion circuit. The difference lies in the linear power supply. The switching power supply has high efficiency, small size, and light weight. It relies on the on-off time of the switch tube to adjust the average output voltage. This kind of power board is called a switching power board.
Feature
Switching power supply circuit boards convert and filter alternating current to obtain stable direct current, so they are widely used in various electronic equipment. Its principle is to rely on the process of switching the DC power supply at high frequency through the transformer, filter capacitor and other components to process the output voltage and current during the transient switching process of the switch tube.
The switching power supply board is composed of transformer, rectifier circuit, filter capacitor, switching tube, control circuit, output circuit and other parts. The transformer is the core part of converting alternating current. The rectifier diode on the rectifier circuit can convert alternating current into direct current. The filter capacitor can make the output voltage and current smoother. The switch control circuit is an important part of turning on and off the entire circuit.
The working mode of the switching power supply board is to switch the power supply and circuit by controlling the switching state of the switching tube. When the switch tube is in the on state, the power circuit can charge the capacitor; when the switch tube is in the off state, the capacitor can be discharged by the current of the load. The control circuit in the circuit can achieve precise control of the circuit through a feedback mechanism, thereby achieving stable and reliable output.
The switching power supply board is an important part of the monitor equipment and provides safe and reliable power supply for the monitor.
Common Faults And Repair Methods
| Common faults and repair methods | Check whether the filter capacitor or voltage stabilizer is damaged. |
| Overload protection | It is possible that the load current is too large or the internal fuse is disconnected. Check the abnormal load. |
| Short circuit protection | Check whether the switch tube is damaged and replace it. |
The difference between a switching power supply board and a power supply board: a power supply board is a board that implements a single power supply function. A power supply board can convert the input power voltage into various levels of working voltages in the device. Putting these on one board forms a circuit board. The switching power supply board is composed of two forms: parallel connection and series connection. It is a power supply system that realizes voltage conversion by switching. The switching power supply board is small in size, light in weight and high in efficiency. These are its biggest features. The difference between the two is Linear power supply, switching power supply is a power supply turned into a circuit. The power supply board is the power supply that supplies the load. The switching power supply board is a power supply system that outputs constant voltage and constant current and realizes voltage conversion by switching. It is a very efficient power supply. However, the output power of the switching power supply is very large.
