VS-P132

Vishay VS-P132 is an advanced, heavy duty thyristor module designed to provide reliable solutions in demanding industrial, utility and transport applications. It has the ability to perform in highly-demanding conditions, and is ideal for applications requiring greater power operation that require robust, reliable and efficient performance.

Application Field

The VS-P132 is a heavy-duty thyristor module, suitable for many industrial and utility applications. It can be used for motor control, heater control, phase angle control, and overvoltage suppression. It is especially suitable for applications needing greater power operation, such as electric drives, AC current measurement and phase control, and adjustable speed drives for conveyors, pumps and fans.

Working Principle

The VS-P132 employs a standard thyristor with a high blocking voltage and low average forward voltage drop Mounted in a robust TO-3 power package, the module features a very low on-state resistance and a high gate threshold. A gate control circuit is built into the module and provides the ability to control the thyristor with respect to current and voltage limits. This ensures a safe and efficient operation in the application.

When the device is energized, the gate voltage across the base-emitter junction of the thyristor switches the device on. The current flowing through the device continues until the SCR is turned off by the gate signal supplied to it. The SCR can be turned on again, provided a suitable signal or power is applied to it.

The VS-P132 is designed to operate with a high-voltage direct current (HVdc) source and a control panel that allows the user to control the device\'s functions and parameters. This includes setting voltage and current limiters for the thyristor, setting the time delay for the start of the SCR action, selecting the operating voltage range and selecting the required operating mode.

Conclusion

The VS-P132 is a reliable and robust thyristor module, suitable for many demanding industrial and utility applications. Thanks to its high blocking voltage, low on-state resistance and high gate threshold, it provides an efficient and long-lasting operation. With its control panel, the user can quickly and easily set the required parameters and make sure that the device operates safely and efficiently.
