Introduction

The EK09W is a rectifier, specifically; a single-phase, snap-action, glass encapsulated thyristor for sensitive switching and power applications. It is a device constructed from silicon compounds and semiconductor ceramic materials, allowing for several different operation methods. The EK09W has a wide range of applications in industrial electronics, including motor control, DC to AC power conversion, heating power control, and more. It is capable of controlling high-voltage and high-power flow, being able to withstand peak voltages up to 1250 volts.

Types

There are two main types of EK09W application fields: AC and DC. The AC application field is primarily used for AC motor speed control, AC household appliance control, AC motor overload protection, and switching AC power supplies. In the DC application field, it is mostly used for controlling high-power DC motors, such as DC-motor power controllers, as well as DC servo motors, operating on DC voltage values from 2V to 1250V.

Applications

The main applications of EK09W rectifiers are AC and DC motor speed control, AC and DC household appliance control, AC and DC motor overload protection, switching AC power supplies, DC to AC power conversion, and high-power flow control. Due to its robust design, it can be used to control high-voltage and high-power applications. It is ideal for use in any application where reliable switching and power performance is required.

Working Principle

The EK09W rectifier works on the principle of thyristorized control. This means it works in two modes: forward breakover and reverse breakover. During the forward breakover mode, electric current flows from anode to cathode, creating a voltage drop that initiates a switching action. During the reverse breakover mode, electric current is blocked from passing from anode to cathode until the voltage across this component has reached a certain threshold, triggering a switching action.

In order for the EK09W rectifier to switch between the two states, a certain gate voltage is required. This voltage is supplied by an external gate circuit. Once the gate voltage is supplied, the component triggers a reverse-breakover, latching in an on state and sending an electric current through the component. This current can then be used to either control a motor or to turn on a power device.

Advantages

The EK09W rectifier is an ideal device for controlling and switching power. Its main advantages include its ability to withstand peak voltages up to 1250 volts and its easy-to-use snap-action system, which does not require complex external circuits. The EK09W also has a very high switching rate, making it suitable for high-speed applications. Additionally, it is highly reliable and offers long-term performance, which is important for industrial use.

Conclusion

The EK09W rectifier is an ideal device for controlling and switching power, providing numerous advantages including its ability to withstand peak voltages up to 1250 volts, its reliable snap action system, and its high switching rate. The EK09W is suitable for a wide range of applications and is capable of controlling both AC and DC voltage up to 1250V. As such, it is an excellent choice for use in a variety of industrial electronics.
