VHF15-12IO5 thyristor modules are part of a family of silicon controlled rectifier (SCR) based components that are used in a variety of applications. They are used to control low power and/or light current applications such as resistive heating, light dimming, temperature control and motor speed control. They provide current reduction, protection, control and switching capabilities.

The VHF15-12IO5 module contains two thyristor components. It has an insulated-gate bipolar transistor (IGBT) and a gate driver IGBT. The two IGBTs are structurally and electrically similar and their purpose is to provide an insulated source and sink of current. The gate driver IGBT is used to turn on and off the gate of the IGBT, which controls the triggering of the thyristor. The module also has a reference voltage circuit, a high voltage cable assembly and a connector.

The VHF15-12IO5 module has a number of application fields. They are used in light dimming, phase control and motor speed control in motor drives and industrial automation applications. The SCR can also be used to control resistive loads such as heaters and ovens. Additionally, the module can be used in DC-AC inverters and UPS systems.

The working principle of the VHF15-12IO5 is quite simple. When the gate voltage reaches the module’s reference voltage, the IGBT is turned on and allows current to flow through the load. When the current reaches the load’s peak value, the SCR turns off and the current is reduced. This process continues until the power supply is switched off. The reference voltage is adjustable for different types of loads.

The VHF15-12IO5 module is a reliable and effective way of controlling and switching low power and light current applications such as light dimming, phase control and resistive heating. The module is easy to install, and the adjustable reference voltage makes it suitable for a wide range of applications. This versatile, cost effective module offers an efficient way to control and switch AC loads.
