1. Single phase thyristor controller is a multifunctional power integrated module that encapsulates a single-phase thyristor main circuit, a phase-shifting trigger control circuit, and two built-in unidirectional thyristors.
2. It features single-phase phase-shifting AC voltage regulation with input voltages of 220VAC and 380VAC. The thyristor output is reliable, stable, and long-lasting.
3. It uses welded chips to maximize load capacity.
4. It can accept inputs of 1-5V, 0-10V, 4-20mA, and a manual 10K potentiometer, without the need for an external power supply, making wiring more convenient.
   
   
5. The module is rectangular in shape and encapsulated with epoxy resin.
6. A suitable heat sink is required during use, and forced air cooling should be enhanced if necessary.
7. It features a flame-retardant engineering plastic shell, comes with a safety cover, and uses a brass heat dissipation base plate.
8. Applications include temperature control for resistive loads, power regulation, voltage regulation, incandescent lamps, temperature adjustment, industrial electric furnaces, ovens, single-phase motor speed control, electrical switch cabinets, and automation control equipment.

When selecting a product, different current margins should be reserved based on the nature of the load. (For resistive loads, select 2-3 times the load current. For inductive or capacitive loads, select 3-5 times the load current.)

According to the relationship between load current and ambient temperature, if the ambient temperature is high or the cooling conditions are poor, the current capacity should be increased. To prevent load short circuits during use, it is required to connect a fast circuit breaker or fast fuse corresponding to this product in series in the load circuit.

For inductive loads, a varistor should be connected in parallel at the output end to prevent damage to the thyristor due to overvoltage. Varistor (MOV) selection: for 240V, choose 430-470V; for 440V, choose 680-750V; for 660V, choose 1100-1200V.

During installation, the contact surface between the heat sink and this product must be flat and smooth, and a layer of thermal grease should be evenly applied to its surface. Finally, tighten and fix the screws with flat washers and spring washers symmetrically.

After the solid-state relay is first operated and stopped, the fixing screws should be tightened again while it is still warm to ensure that the base plate of the solid-state relay and the surface of the heat sink are in close contact, achieving optimal heat dissipation.

The nominal current of different models of solid-state relays is the nominal current at an ambient temperature of 40°C, so adequate cooling is necessary.

Do not use a multimeter on the load end to determine the quality of the product!
