Hi guys
I have an Omron relay part# G5V-1-DC24 with contact rating:
1A at 24 VDC
or 0.5A at 115VAC
I want to use it for 12VDC ,is the rating of the contacts remain at 1A or could be more than that?
Thanks
Hi every one.
After this long round of discussion my origional question did not receive a clear definite answer:
Does the magnetizing current (Im) change with load current or it stays constant ?
That is my question- I wish to find clear answer.
Thanks
So,what I understand is that primary leakage inductance acts exactly as the primary wire resistance and it will cause the hysteresis loop to reduce its height as the load current increases-Is that what you mean?
Skogsgurra thaks for help, the transformer theory indicates that the hysteresis loop does not change with the load current, so the magnetizing flux @ is assumed to be constant and so d@/dt is assumed to be costant.
Thanks,but the voltage across the coupling inductance L1(E1)remains constant =N1(d@/dt)
So, the induced secondary voltage E2= E1(N2/N1)=N2(d@/dt) remains constant and does not depend on the voltage drop on the primary leakage inductace.
@ is the magnetizing flux which is constant.
I have difficulty to understand the theory of how the transformer acually works and have a question regarding to that:
The primary winding of a transformer consists of two parts:
1- Primary leakage inductance Lp1
2-Primary coupling inductance L1
neglect the wiring resistance.
So the total...
