Three-phase solid-state relay (enhanced type) AC solid-state relay (casing color: black or white, random) TSR-150DA-R without heatsink

1、Multi Function: Photoelectric isolation between the relay control circuit and the load circuit; which can also control silicon output, zero current shut down, and voltage zero crossing open.

2、Compatible Characteristics: The relay control signal is compatible with TTL logic; with a safety shield; the three phase starting characteristics are also consistent.

3、Welding Process: Relay with flame retardant engineering plastic shell, copper base plate, industrial grade welding process.

4、Use Equipment: The relay needs to be equipped with a suitable radiator when in use, and forced air cooling should be installed if necessary.

5、Wide Range of Uses: This relay has a wide range of uses and can be used for resistive loads: such as temperature control, industrial electric stoves, motors, electrical switch cabinets, automatic control and other equipment on and off.

Note:

1. When choosing a product, you should leave a different margin in the current grade according to the nature of the load. (For resistive load, it can be selected by 2 to 3 times the load current. For inductive or capacitive load, it can be selected by 3 to 5 times the load current, and for the motor it is more than 5 times.)

2. According to the relationship between the load current and the ambient temperature, when the ambient temperature is high or the heat dissipation conditions are not good. The current capacity should be increased. In order to prevent the load from being short circuited during use, it is required to connect a fast disconnect switch or fast fuse corresponding to this product in series in the load circuit.

3. In The Case Of Inductive Load, A Varistor Should Be connected in parallel to the output terminal to prevent damage to the thyristor during over voltage. Varistor (MOV) options: 430-470V for 240V and 680-750V for 440V.

4. During installation, the contact surface between the radiator and the product must be flat and clean, and a layer of thermally conductive silicone grease should be evenly coated on the surface, and finally the screws with flat washers and spring washers should be tightened symmetrically.

5. When the solid state relay is shut down for the first time, the fixing screws should be tightened while the residual temperature is still there to make the solid state relay base plate and the surface of the radiator closely contact to achieve the ideal heat dissipation effect.

6. The nominal current of different models of solid state relays is the nominal current when the ambient temperature is 40℃, so the heat dissipation must be sufficient! !

7. Be careful not to use a multimeter on the load side to betray the quality of the product!
