Three-phase solid-state relay, fast switching speed, noiseless, AC to SSR 90-250VAC 24-480VAC TSR 15AA H (15A)

Features: 1. AC to AC: With this solid-state relay, you can control a 24-480 VAC circuit via a 90-250 VAC console voltage, making it compatible with most temperature controllers and switching consoles. 2. Ensure Safety: The solid-state relay eliminates the need for multiple high-voltage circuits in the console, allowing for remote control of fans, pumps, and other devices. 3. High Performance: Features include no sparking, no noise, fast switching speed, corrosion resistance, moisture and vibration resistance, high reliability, and good electromagnetic compatibility. 4. Wide Application: The solid-state relay is ideal for automatic process control applications and is a crucial component of temperature controllers and other mechanical control systems. 5. CONTACTLESS SWITCH: A superior contactless switch consisting of a shell, electronic circuit board, heat dissipation base plate, silicon-controlled rectifier, and photoelectric element, has a wide range of applications.

When selecting products, different current ratings should be considered depending on the load properties. (For a resistive load, the current rating can be selected based on 2 or 3 times the load current. For an inductive or capacitive load, it can be selected based on 3 to 5 times the load current, and for a motor, more than 5 times.) 2. Depending on the relationship between the load current and the ambient temperature, when the ambient temperature is high or heat dissipation conditions are poor, the current rating should be increased. To prevent a load short circuit during operation, it is necessary to connect the appropriate quick-disconnect switch or fast-blow fuse in series in the load circuit. 3. In the case of an inductive load, a voltage-sensitive resistor should be connected in parallel to the output terminal to prevent damage to the thyristor in case of overvoltage. Varistor (MOV) selection: 430-470V to 240V, 680-750V to 440V. 4. During installation, the contact surface between the heat sink and the product must be flat and smooth, and the surface must be evenly coated with a layer of thermally conductive silicone grease. Finally, the screws with flat washers and spring washers must be tightened and secured symmetrically. 5. When the solid-state relay is first switched on and off, its residual temperature should be used to tighten the mounting screws so that the base plate of the solid-state relay and the surface of the heat sink can make close contact and achieve optimal heat dissipation. 6. The rated current of the different models of solid-state relays is the rated current when
