PS2521-1-A

Introduction

PS2521-1-A is a photovoltaic output optoisolator which consists of an infrared LED and a photodetector mounted face to face in the same package. It is used to electrically isolate an output signal from the control signal. The device is ideal for applications with either AC or DC signals.

Application Field

The PS2521-1-A optoisolator is widely used in applications such as power supplies, motor drive circuits, motor control, interface circuits, and other industrial control circuits. It is particularly useful for applications which require a high voltage isolation between the input signal and the output control signal.

Features

The PS2521-1-A optoisolator offers these features:

• Very high direct input-to-output isolation of up to 2500Vrms
• High input-to-output isolation voltage of up to 300Vdc
• Low drive current of no more than 7mA
• Low input capacitance of only 0.5pF
• Low power consumption

Working Principle

The PS2521-1-A optoisolator operates on the principle of electron exchange. The LED emits light when a control voltage is applied across its terminals. This light is then detected by the photodetector, which in turn generates a corresponding electrical signal. This electrical signal is then used to control the output signal.

The primary benefit of the PS2521-1-A optoisolator is its high isolation voltage, which is necessary for applications involving high voltages. This isolation voltage separates the input control signal from the output signal, preventing any interference or short circuiting. Thus, it ensures optimal performance from the output signal.

Conclusion

PS2521-1-A is a photovoltaic output optoisolator which is specifically designed for applications which require a high voltage isolation between the input signal and the output control signal. It offers high input-to-output isolation voltage of up to 300Vdc, low power consumption and low drive current of no more than 7mA. The device is widely used in applications such as power supplies, motor drive circuits, motor control, interface circuits, and other industrial control circuits.
