I am looking for a linear bench supply and I came across this one that said "linear" but reading further it said " PWM voltage stabilization. I emailed the seller to find our which it was and got this answer:
"Thanks for your letter and your interests in our product.
The item uses PWM switching voltage stabilizer and MOS linear adjustment mode."
Is this double talk for a switching power supply by a seller repeating the blurb that came from China with the PS or is it some hybrid technology I am unaware of? Are they talking about the DC output that is fed back to the PWM controller to regulate the supply? Thanks.
I have since found another candidate Mastech/Voltq that is definitely linear, less than a mv of noise and 4 digit neters that resolve to 1ma. Nice for general use but I am curious about the first ad.
