Hello Everyone,
I'm new to your forum, and by no means an electronics expert. I have a basic knowledge, that's about all.
I'm a general engineer for a company dealing with used automotive parts, and I have been tasked with developing a method to test solenoids in transmissions. These solenoids operate on a 12 VDC Pulse Width Modulated signal. Some of the solenoids will be as low as 1 Ohm, so the current can be fairly high. I would like to design the tester for around 30 amps to ensure we can test anything that might come up in the future.
I need to produce this 12 VDC PWM signal. I need to be able to set the frequency before the test begins, and I need to be able to control Pulse Width during the test. The tester will be completely automated, programmed with LabVIEW, and I need to control the PWM signal from the LabVIEW program.
What I need from you guys is help finding the right hardware for this job. There are several PWM boards available through National Instruments, but they are all lower current. I would like something that is built and ready to use, no assembly necessary.
Thanks for the help.
