Solid State Relays (SSRs) are a type of electronic switching device which controls electrical power or a circuit with the help of a low power electronic signal. SSRs are available in various types of form factors, including printed circuit boards (PCB), module-based packages, and light emitting diode (LED) lamps, among others. HA4890-10 is a particular type of SSR that is used for switching electrical loads from low input voltage and power. In this article, we will discuss the application field and working principle of HA4890-10 SSRs.

HA4890-10 SSRs are designed to be used in motor control applications, such as those found on electric bikes, pumps, and conveyors, as well as other operations which require control of larger electrical loads. This SSR is an efficient alternative to mechanical relays, as they provide high switching performance and fast response times. The HA4890-10 SSRs also provide a high level of electrical isolation, which helps to protect sensitive devices and circuits from accidental damage.

The HA4890-10 SSRs consist of a semiconductor based chip, which is connected to the power source and the load. When a current is applied to the input terminals, the chip is activated and the SSR will then switch the power supply between the two terminals. The switching process is done without the application of mechanical force and can be done at high speed. This makes the HA4890-10 SSRs ideal for applications which require fast response times and high switching performance.

The HA4890-10 SSRs have a wide operating temperature range from -40°C to +85°C, and a switching current range of 0.2A to 10A. This makes them suitable for a variety of applications. The HA4890-10 SSRs also feature a low on-state resistance of 0.1Ω, which helps reduce power losses and improves the efficiency of the circuits.

In addition to these features, the HA4890-10 SSRs have an integrated current sense and a built-in thermal protection circuit for extra safety. The current sense will detect any over-current situation and immediately de-energize the SSR, preventing any dangerous electrical conditions. The thermal protection circuit helps protect the SSR from excessive temperatures, preventing it from becoming a fire hazard or damaging the load.

The combination of fast response time, high switching performance, low on-state resistance, and the integrated safety features makes the HA4890-10 SSRs an ideal choice for motor control applications. The SSRs are relatively low cost and easy to install and maintain, which makes them even more attractive to users. With their wide range of features and applications, the HA4890-10 SSRs are sure to be a hit with electronic engineers and hobbyists alike.
