Excellent Bench Variable Vol/ Bench Supplyt
Sure, it's lightweight, switching power supply instead of of the "heavies" which use a heavy and stable step-down transformer. Switch supplies have got a bad name over the years, primarily because of the RF hash they are prone to produce on nearby AM/SSB receivers. But, this unit produces no HF interference. Indeed, I have several other switching supplies which do not either --- not a bit. On the other hand, I have had switching supplies that I needed to toss away, or not use anywhere my ham shack equipment. Switching supplies seem to have improved over recent years, proving that the inherent RF noise they produce can be suppressed. I do have a heavy, DC-transformer 40-amp supply, and this switching supply makes no more noise than the "big boy." There is also almost no AC riffle leak-thru; another bane of some switching supplies.
This supply will give you want you want in a bench supply. For those hobbyists and folks who need a variable output power supply - and who doesn't for testing and equipment operation, this will fill the bill. Like most switchers, it's small and light, taking up little bench space, and provides the wide range of DC voltages advertised. The digital readouts are a plus, and tested against a calibrated VTVM, are accurate to within one-tenth of a volt or ampere. Of course I would always rather have a conventional DC-transformed, rectified and filtered supply, but had all switchers performed as well as this one did, I might not feel that way. :)Read full review
