How are you expecting to obtain "over voltage" on what should be a regulated voltage output?

So I guess you just press the OVP button, and if a spike on the line comes along it clamps it. Is that what it's for?

I thought it was an upper voltage limit you could set so that if, while connected to a circuit, some careless person comes along , or you have a blond moment, and accidently spins the adjust knob it would kill the output when it hits that limit to save frying your circuit.

That's exactly what I thought, but I can't seem to get it to do that. The over current seems to work correctly. You set it for the max current you want, then turn on the output, press the OCP button, and when you bring up the voltage, and the current rises above that set limit, it shuts down the output. Can't seem to figure out what their implementation for the OVP is though. Other than that, this supply is a real winner! For the money it's accurate, stable, and actually looks pretty nice.
