Hello, I have a constant 50KHz, 1.9A RMS sinusoidal current flowing in a 10R resistor. Every now and again, I wish to short out this resistor with a relay. (as you know, when the relay shorts the resistor out, the 1.9A current will then flow through the relay)
Is this relay ok to do this shorting job?
The peak resistor voltage is 27V, and the relay is rated to 30VDC. (I assumed I have to look at the relays "DC" rating, since its AC rating is for 50Hz AC , and 50KHz AC is basically going to appear like DC to the relay because the contact arc will not extinguish after the zero crossing as the volts rise up again very quickly with 50KHz AC?)
