The LH1520AACTR is a type of solid state relay, typically used as a protective safety system for a wide variety of applications. It is designed to provide fast-acting, low-power switching of higher-voltage loads, in addition to providing high-level protection and improved reliability. The LH1520AACTR is an effective and reliable solution when used in applications requiring a high degree of safety, such as industrial, military, medical, and aerospace applications.

The LH1520AACTR solid state relay utilizes fast-acting thyristors, controlled by an AC voltage input, to switch the output load current. The relay is designed to provide reliable, repeatable performance with an efficiency rating over 97%. The devices offer a wide range of output choices, including 24 VDC, 36 VDC, 48 VDC, 60 VDC, 120 VAC, and 230 VAC. The maximum output for the relay is 20 A@24 VDC, 10 A@36 VDC, 7 A@48 VDC, 6 A@60 VDC, 8 A@120 VAC, and 4 A@230 VAC.

The operating voltage of the LH1520AACTR is 120 VAC. It is designed with an isolating circuit breaker, which prevents overloading of the relay due to short circuits in the connected circuit. The breaker also provides additional protection against surges in the line. This breaker is energised during normal operation, when the desired AC voltage is connected between the input terminals, and de-energised when the AC voltage is removed.

The LH1520AACTR can be operated in two modes: latching and momentary. In latching mode, once the relay is energised, it will remain in the energised state until the AC voltage is removed from the input terminals. In momentary mode, the relay will energise when the AC voltage is connected, and will de-energise once the AC voltage is removed. The relay can also be used in combination with an external timer, to allow for delayed switching of the output.

The LH1520AACTR is designed with a wide range of protection features for increased safety and reliability. These include undervoltage protection, input overvoltage protection, thermal protection, short circuit protection, arc suppression, and AC mains detection. The relay also has built-in surge suppressors, which provide additional protection against electromagnetic interference and power surges.

The LH1520AACTR solid state relay is designed to be a reliable, cost effective, and versatile solution to many applications requiring isolated electrical switching solutions. Its small size, fast switching speeds, and high-reliability make it an ideal choice for many applications, such as industrial, military, medical, and aerospace. The relay is easy to integrate into existing systems, making it an ideal solution for engineers and designers seeking an efficient and reliable solution.
