TIANHAO (THE) GTJ48-40A Solid State Relay
The TIANHAO (THE) GTJ48-40A is a highly reliable single-phase Solid State Relay (SSR) designed for efficient DC-to-AC switching. Manufactured by Wuxi Tianhao Electron Co., Ltd., this relay utilizes a 3-32VDC input control voltage (constant current type) to manage AC load voltages ranging from 24 to 480VAC, supporting a robust rated current of 40A. Engineered specifically for resistive loads, the GTJ48-40A guarantees optimal performance with a low on-state voltage drop of less than 1.13V and an off-state leakage current below 10mA. Safety and convenience are prioritized through its integrated transparent protective cover, secure screw terminals, and a built-in LED status indicator for quick visual diagnostics. Backed by rigorous TUV and CE certifications, this solid state relay is an excellent choice for industrial automation, commercial heating controls, and precision power management systems.
