Ambulance power inverter or medical use power inverter for oxygen machine

The power inverter with spec such as dc 12v to 110v is also widely used in medical circumstances, such as ambulance power inverter and power inverter for oxygen machine, let’s have a detail look as below.

What is difference between Ambulance power inverter and normal inverter?

Many people are familiar with inverters. But when it comes to ambulance power inverter, some friends may feel strange. This inverter was first popular abroad. With the increase of domestic ambulances in China, people gradually realized the function and convenience of the ambulance inverter.

Ambulance power inverters have many functions. This article will help you understand the functions of ambulance inverters. But before doing so, you need to know about the role of the inverter

The inverter is simply the ambulance power supply equipment. It is different from ordinary car charger in that the output voltage of car charger is DC12-24V. The output voltage of the inverter in China or European country is AC220V.While in USA or Japan or Canada etc, the output voltage is AC110V, you need choose power inverter for dc 12v to 110v. The inverter is used to convert direct current (battery, battery) into current (usually 220V, 50Hz sine wave). It consists of boost circuit, inverter bridge, control logic and filter circuit.

Characteristics of inverter

1. High conversion efficiency and fast startup;

2. Good safety performance: the product has five protection functions: short circuit, overload, over/under voltage and over temperature;

3. Good physical performance: the product adopts an all aluminum shell, with good heat dissipation performance, hard oxidation treatment on the surface, good friction resistance, and resistance to certain external force extrusion or impact.

4. Strong load adaptability and stability;

Selection of ambulance inverter

Because of the particularity of ambulances, the on-board electrical appliances are all medical equipment. Because the medical equipment detects the weak bioelectrical signals of the human body, the requirements for electrical energy are very high. If there are too many interference signals in the electrical energy, the detection effect will be affected, and false diagnosis will occur. In order to avoid signal interference, the power frequency inverter with isolation system is generally used.

The power frequency inverter has a simple structure, and various protection functions can be realized under low voltage. There is a power frequency transformer between the inverter power supply and the load, so the inverter operates stably, reliably, has strong overload capacity and impact resistance, and can suppress the high-order harmonic components in the waveform.

What is difference between power inverter for oxygen machine and normal ones?

The power inverter for oxygen machine should choose the one with UPS function, then it can support the oxygen continually.
