A solid state relay is an electronic switching device that switches on or off when an external voltage or current is applied. They are controlled by the use of optically isolated inputs which isolate the switching of the voltage from the supplying electricity. CPC1025NTR is one of them. This solid state relay has a high power ratings, which makes it suitable for higher power applications such as air conditioners, electric ovens, etc.

The CPC1025NTR is a 4-pin SSR with a maximum current rating of 25A at 250VAC and an off-state current of less than 130 mA. It has a maximum on-state voltage drop of 2.4V and a thermal resistance of 329K/W. The relay is LED controlled and is suitable for resistive, inductive and capacitive loads. The addition of a heat sink can further reduce the overcurrent, overtemperature characteristics of the relay.

The typical application field for the CPC1025NTR includes industrial equipment, pumps, compressors, presses and motors. The relay is also suitable for temperature control systems as well as for electronic circuits and power switch upgrades. In all these applications the most important factor is reliability.

The working principle of the CPC1025NTR is based on the sensing of an isolation resistance of about 4K ohms. When a certain voltage is applied to this terminal, a current flows through the relay coil. This current turns on the LED switch which in turn activates the triac or SCR connected to the relay. The triac or SCR acts like a switch, allowing current to flow through the load.

The CPC1025NTR contains a secure lockout feature that prevents any unexpected switching on or off of the relay. As a safety measure, the relay is designed to disconnect the load to prevent any unexpected power losses. Additionally, the device also has an internal over-temperature and over-current protection feature that will shut off the device in case of an overload or an over temperature condition.

In addition to these features, the CPC1025NTR SSR also provides a wide range of standard features that make it suitable for various applications. These include a high isolation voltage rating, good dielectric strength, a wide input voltage range, low output voltage drop, easy installation and a high level of safety.

The CPC1025NTR SSR is an excellent choice for power switching applications that require fast, reliable and safe operation. This device is suitable for both home and industrial applications, as its features and various safety protections make it ideal for any use.
