The FS1H004NF is an advanced silicon-activated rectifier. It’s designed for applications including VoIP, switching power supplies, DC/DC converter, inverters, balancers, and many other applications. It’s an ideal replacement for mercury-relay based SSRs that are no longer widely available. Its products have a number of advantages over mercury-relay SSRs.

Application Field

The FS1H004NF silicon-activated rectifier is suitable for various industrial applications. As it is low-voltage and lightweight, it is especially used in signal-control applications such as VoIP, switching power supplies, DC/DC converters, and most inverters. When it is used to replace mercury-relay based SSRs, it is very energy-efficient as the FS1H004NF itself consumes literately no power. It also provides a higher switching frequency and can mainly operate at 30KHz, which meets the needs of many industrial applications.

Working Principle

The FS1H004NF silicon-activated rectifier is made up of two parts: the gate circuit and the main circuit. The gate circuit is responsible for the input signal control, while the main circuit is responsible for the power output. It works by switching on and off the main circuit based on the input signal voltage. When the input signal is 0, the power output is 0, and when it is above a certain threshold, the main circuit is switched on and supplies power to the load. The FS1H004NF can then supply more power than a mercury-relay SSR of the same size and can operate at higher currents with fewer heat problems. It is also of a much smaller size, making it easily incorporated into designs.

The FS1H004NF can provide precise power control, which cannot be achieved with mercury SSRs. This precision means that it can be used to control the small amounts of power used in signal-control applications and can also be used to precisely control power supply for low-signal applications such as DC/DC converters. It also has a very low leakage current, so it can be used in applications where no power is generated when the power is off.

In conclusion, the FS1H004NF is an advanced silicon-activated rectifier that provides power control and accurate energy management. It can be used in many industrial applications, including VoIP, switching power supplies, DC/DC converters, and most inverters. It is also of a much smaller size, making it easy to incorporate into designs. Furthermore, it features a low leakage current and its precision makes it ideal for signal-control applications.
