We do not have the circuit; the customer send us this schematic as part of their spec sheet. What the customer wants us to do is load the secondaries and excite the primaries with this circuit.
We received this from a customer and it is designed for a burn-in test for multiple transformers with the secondary loaded. But I agree; this is not the way I would have done it!:confused:
If it is a switch or some sort of circuit protection, then it is definitely in the wrong spot. Perhaps...
Does anybody know what component that is between the collector of the transistor and the load? I have never seen anything like this and it is not in any of my reference books. Thanks.
No, unfortunately not; it just has knobs to adjust the frequency and output.
I am now considering the digital potentiometer and the relay idea.
The digital potentiometer will require a way to adjust it manually; probably using a monentary contact toggle switch. (up to increase output...
If the test is scheduled to be completed during the work day, for example at 9:00am, we simply turn down the output on the AC power supply and turn off the temp chambers.
First time user here...
I have a project that I am assigned at work. We manufacture customer inductors and transformers and part of the testing involves applying power, either AC or DC, at elevated temperatures. Some of the tests are completed during the night or weekends and we use timers to...
