Flux Soldered General Purpose Power Relay For Electronic Power Meter

 

For the relay load, generally it regards pure load as the rated load, and sometimes it will increase the conditions of some inductive load and TV load conditions. It is usually satisfied to use it according to the rated load given by us. But in order to optimize and improve the reliability of the letter patience, we need to use the actual use of derating.
 

Reference of derived for several typical loads:
A: Resistive load rating: usually derating 75% of rated capacity
B: Capacitive load rating: usually derating 75% of the rated load, and it needs to series a resistor to reduce the impact current.
C: Inductive load rating: usually derating 40% of the rated load, and it needs to use an arc suppression of the absorption circuit.
D: Motor load rating: Normally the derating is 20% of the rated load, and it needs to adopt a circuit that suppresses the impulse current and the arc is also required.
E: Tungsten lamp load rating: usually derating 10% of the rated load, and it needs a series of resistance to reduce the impact current.
