Attenuators

Attenuators are electrical components used to reduce power, voltage, or current levels. The PXV1220S-2DBN1-T02 is a type of attenuator known as a pulse-width modulation (PWM) variable resistor. It offers excellent control of the DC voltage level connected to a load. The device draws a minimum of current and dissipates a maximum of 0.4 watts of power.

PXV1220S-2DBN1-T02 Application Field

The PXV1220S-2DBN1-T02 is primarily used in applications where precise control is needed for controlling the DC voltage connected to a load. This could include control of DC motors for motor-driven systems, manual control of DC LED brightness, and for adjusting the voltage level of power supplies in audio systems. The device is also ideal for any other circuit application that requires accurate voltage control.

PXV1220S-2DBN1-T02 Working Principle

The PXV1220S-2DBN1-T02 is a PWM variable resistor with adjustable current limiting. It has an input voltage of 8 to 35 volts and a single output with a maximum rating of 30 volts. The output voltage is adjustable by adjusting the dial of the knob on the device.This attenuator works on the principle of pulse width modulation. The output voltage is determined by the width of the pulses applied to the load. The duty cycle of the output pulses is adjustable with the knob. A longer duty cycle will produce a higher voltage level at the output while a shorter duty cycle will produce a lower voltage level at the output.The device features two separate circuits, one for the input and another for the output. The input circuit is a series combination of resistors and capacitors while the output circuit is a bridge circuit. A pulse width comparator is used to determine the width of the pulses applied to the load. The pulse width comparator is adjusted by the knob on the device and includes a resistor for current limiting.

Conclusion

The PXV1220S-2DBN1-T02 is an excellent choice for controlling DC voltage levels for a wide variety of applications. It offers a simple yet effective way to adjust voltage levels with precision and accuracy. The device is highly reliable and can be used in a variety of settings. It is an ideal choice for anyone looking to save money and time while still getting reliable and precise voltage control.
