1300920180

The 1300920180 is an accessory commonly used in many circuit designs. Its most common use is as current-limiting and short-circuit protection. In addition, it can also be used in DC power supply and control circuit, small motor driver circuit and solenoid, etc. To operate.

The 1300920180 consists of two main parts: an SCR (Silicon Controllable Rectifier) and a MOV (Metal Oxide Varistor). The SCR is controlled by a gate supply voltage connected from a control circuit. The MOV is usually attached to the anode of the SCR. Also, the MOV will provide a very low impedance between the anode of the SCR and ground. This type of coupling uses a MOT (Magnetorheological) for power series protection.

The 1300920180 works in two ways. First, when the supply voltage is normal, the SCR stays in its normal off state with its anode floating. This is because there is no gate voltage that enables the SCR to turn on. Secondly, when an over-voltage or over-current condition occurs, a current will flow through the MOV and gate circuit which causes the SCR to turn on. The SCR then begins to conduct current, thus limiting the over-current or over-voltage and protecting the device.

The 1300920180 is generally used in power circuit designs, especially as current-limiting and short-circuit protection. It is widely used in many electronic and electrical products, ranging from home appliances to industrial equipments. It is used to protect circuits against over-voltage or over-current conditions, thus ensuring a safe and reliable direct current power supply for different applications.

When it comes to installation, the 1300920180 should be installed in series with the power supply line. The rated value of the MOV should be chosen according to the specific application design requirements. In addition, the SCR should be installed properly according to the current flow direction. Installing the 1300920180 upside down is not recommended, as it may cause an unexpected conduction of current.

In conclusion, the 1300920180 is a commonly used accessory for current-limiting and short-circuit protection. Its working principle is quite simple: when an over-voltage or over-current situation occurs, the SCR will turn on and conduct current, thus limiting the current or voltage and protecting the device. Installing it correctly is important for correct operation and to ensure a safe and reliable power supply in any application.
