Power Inverter for ambulance application

Ambulance power inverter has 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 is AC220V. 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.

Inverters are widely used in mobile phones, laptops, digital cameras, cameras, lighting lamps, electric razors, CD players, game consoles, handheld computers, electric tools, car refrigerators, and various tourism, camping, medical emergency appliances.

Features 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;

Precautions:

When enjoying the convenience brought by the on-board inverter, the safety problem cannot be ignored. The on-board inverter can output a voltage as high as 220 V, which is very dangerous in the relatively closed space inside the vehicle. Therefore, when using the vehicle power supply, it must be kept away from children to prevent electric shock.

In summer, the sun is fierce, but many people do not have the habit of placing sun visors, which makes the on-board inverter explode when the temperature is too high after being exposed to the sun. Therefore, the inverter should always be careful not to work in a high temperature environment. In addition, do not place objects on the inverter in working state, which may lead to poor heat dissipation performance.

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.

Carspa ambulance power inverter is produced with below features:

1. dual eletrical inductor to ensure perfect wave filtering.
2. Big capacitor and enough quantity to ensure good THD.
3. Enlarged rear stage MOSFET ensures powerful surge power for medical equipments.
