massive, heavy, but accurate voltage output and shows live amp usage.
I'm not sure how old this device is now, the one I bagged second had is in very good condition. The power supply is accurate delivering the correct voltage that I set. It also gives accurate real time display of the current being used by the circuit. Very helpful when thinking about battery consumption or what is required from an alternate power supply for your device.
This particular version has the option of combining the two channels in different ways, isolated, parallel, series, tracking.
It's massive, heavy but has retro chique about it.
