Selection rules
Calculate the current size
Equipment current ÷ coefficient = specification current
Specification current × coefficient = equipment current
Note: resistive load factor 0.2-0.3, inductive load factor 0.1-0.2
Note: The specification current is the inrush current, not the long-term working current
The current level and model of the relay load output terminal are as follows:
Note:
In the case of resistive load, the solid-state current level should be greater than or equal to 3 times the rated current of the load.
When the load is a DC motor, the solid-state current level must be greater than or equal to 5-6 times the rated current of the motor.
When connecting loads such as electromagnets and coils, the solid-state current level should be greater than or equal to 5 times the rated current of the load.
When connecting a capacitive load, the current level of the solid state must be greater than 10 times the rated current of the load.
Example: The load is a heating tube: three-phase 380V, each phase current is 15A.
Choose three-phase 50A solid state, model LSR-TH3Z50D3.
