QPX600D rocks

5.0

I can't say enough good things about this power supply. I didn't realize it when I purchased the QPX600D that its ratings are really 600W (CH1) 600W (CH2). The part number has "600" in the title so I assumed 600W was the total output for the box. It was a pleasant surprise to see this supply is more versatile than the QPX1200 series but equally as powerful. Both CH1 & CH2 can be added in series or parallel for up to 160V or 100A. A beast for the bench yet sensitive enough for logic board testing. CH2 can be set to track from 5%-2000% of CH1. Other tracking modes assist with series and parallel channel combinations. Current limits are adjustable in increments of 10mA. I would have preferred limits down to 1mA resolution but a small 50W bench supply can be used below 10mA resolution. I have been meaning to design a mA or sub-mA limiter to be used with any supply. Eventually :) The supply is very quiet until pulling > 6A/12V for one of my test setups. After this power level the fan does kick up a notch. Not sure if the fan goes beyond this speed (noise level) but it is not distracting at ~70W. The user interface is great. You even have access to fine tuning like independent contrast of each channels LCD. This is handy depending on whether sitting above or below eye level. Contrast can be optimized for best viewing angles. These are not the least expensive supplies around but I would definitely buy a second when the time comes. The only difference might be upgrading to the QPX600DP model for ethernet and other digital connectivity. Both have access to analog slave control via the rear panel if needed. A project for an ESP32 and 24-bit audio DACs also on the to do list. Overall I love the QPX line. Would recommend to anyone looking for an intuitive and versatile supply.
