Thyristors - SCRs are semiconductor devices consisting of four layers of alternating P-type and N-type materials.It is a kind of bi-directional semiconductor device, which is made up of a PNPN structure when triggered, it can allow current to flow in one direction and block in the other.The VS-ST180S12M1L is a 3-phase thyristor module with a maximum current rating of 400 Amps. This module consists of six SCRs with a voltage blocking capability of up to 180 Volts. The module features 600 VAC fired via an RC network and has a typical turn-off time of 30mS.

Thyristors are often used in switches and circuit protection applications. They are used as switching elements in power circuits, as they can control high power at load levels way beyond their own ratings. The VS-ST180S12M1L is often used in various applications including motor starters, power converters, power supplies, and Robot controllers. This thyristor module can be used for rectification, chopper circuits, AC switching, and a variety of other devices.

The working principle of the VS-ST180S12M1L is based on the operation of forward-blocking and reverse blocking. When enough current is applied to the anode and cathode, a forward bias is created that ionizes the PNPN structure, causing current to flow in a forward direction and blocking any current in the opposite direction. This creates a rectifying action and the thyristor will remain in its ‘on’ position until the current is removed or reduced below a certain value.

To turn off the thyristor, the reverse bias must be increased to the point that the thyristor breaks down and current is interrupted; this is called reverse-blocking. The VS-ST180S12M1L features a 600V Fired AC circuit which provides reliable control with high accuracy. This is due to the AC being modulated at the desired frequency, thus providing fast and reliable switching capabilities.

The VS-ST180S12M1L is an excellent option for a variety of high-powered applications. The combination of its high conduction current, adjustable firing angle, high voltage rating, and fast turn-off time make it a great choice for demanding applications. This thyristor module is also suitable for use in circuits requiring high power due to its maximum current rating of 400 Amps. The VS-ST180S12M1L is an ideal choice for applications requiring reliable control, fast turn-off, adjustable firing angle and high voltage rating.
