Can You recommend a great power supply for lab experiments (possibly AC and DC)?
I am looking for some suggestions on a really good experimental power supply I can buy for some simple benchtop experiments. Can someone recommend a good one or a good supplier?
I went to a surplus store, and they had a brand new single for $200 with 5A/ 0-30V DC with meters...The guy said AC ones are hard to get.
I wasn't that impressed.
I wonder if they sell ones that can do 0-120v DC and AC (adjustable frequency, etc)? Dual? In sort of the same price range.
Or would I have to build circuits do to this? Maybe I need a signal generator instead?
It seems strange they wouldn't have a good one like this on the market for a reasonable price, that can do a lot of stuff.
I got a great digital multimeter for example for 80 bucks that can do just about anything.
I have an EE degree, but haven't touched the stuff in 15 years. (done only software stuff). I would like to try some very simple experiments and play with diodes, coils, and transistors
Thanks for any pointers!
Usually, you won't find both AC and DC output in one power supply. Most benchtop supplies are DC output. You usually have choices in the number of output voltages, the output current of each, and some other features which usually aren't that important (programmability). I personally own an Agilent E3630 supply which offers three output voltages (each is DC) and is fairly low noise in its output (good for analog circuits). We have some similar supplies on our benches at work from a different manufacturer, but these triple output supplies normally cost around $400 on up.
I attached a website link below for a company I have used to buy test equipement including power supplies.
If you need an AC supply at 60 Hz (assume you are in US), then you can find a variable transformer, also known as a Variac, and use it to step up or down the line voltage. These work at other frequencies too (50 Hz). Variac is trademarked, but is often used as a shorter name for variable transformers. Cost of one of these is on par with the cost of a good DC bench supply. Be careful on the wiring if you choose to do this!!
Hope this helps...

West System Vacuum Bagging Kit,equipment & Materials #885 6 Venturi Generator
USD 119.99 West System Vacuum Bagging Kit,equipment & Materials #885 6 Venturi Generator . Vacuum bagging is a clamping system used for laminating a wide range of fabrics, core materials and veneers. It offers many advantages over conventional clamping. For repairs and composite construction, it uses atmospheric pressure to deliver firm even clamping pressure over the entire surface area, regardless of the type or quantity of material being laminated. By laminating over simple molds, composites can be molded into a wide range of functional shapes.#879 Release FabricEconomical Release Fabric is a tough, finely woven nylon fabric treated with a release agent. It is used to separate the absorber, breather and vacuum bag from the laminate in vacuum bagging operations. Excess epoxy bleeds through and is peeled from the cured laminate along with the Release Fabric. It's also used in hand lay-up applications to allow more squeegee pressure and protect the lay-up from contamination. Peels easily and leaves a smooth textured surface, ready for bonding or finishing. Not recommended for post-cure temperatures over 120F (49C). Available in 60" wide x 2 yd., and 10 yd. rolls; also in 60" x 9" sheets.#881 Breather FabricBreather Fabric is a lightweight, polyester blanket that provides excellent air passage within the vacuum envelope while it absorbs excess epoxy. Available in 45" wide x 2.7 yd., and 10 yd. rolls.#882 Vacuum Bag FilmClear, heat-stabilized, modified nylon resin film. Can be used at temperatures up to 350F (176C) for typical composite cure cycle times. A tough, stretchable film for high vacuum pressures. Available in 60" wide x 2 yd., and 20 yd. rolls.#883 Vacuum Bag SealantMastic tape sealant for airtight seals between vacuum bags and molds. Easy to work around difficult angles, patching small leaks in the vacuum system. Available in 1/2" wide x 25' roll.#885 Vacuum Bagging KitA complete starter kit for room temperature repairs and small laminating projects up to 13 square feet. The kit includes: 32-page manual on ''Advanced Vacuum Bagging Techniques.'' Instructions. Venturi vacuum generator. Vacuum cups. 1/4'' I.D. vacuum tubing (10'). Vacuum gauge. Junction ''T'' barbs (2). Release fabric (15 sq. ft.). Breather fabric (15 sq. ft.). Vacuum bag film (15 sq. ft.). Vacuum bag sealant (25 sq. ft.). The venturi generator develops over 20 inches Hg (mercury) of vacuum (10 psi). It is designed to run off of conventional shop air compressors delivering at least 65 psi at 3.5 SCFM. At 0 inches Hg it will evacuate 2.2 SCFM. The operating range is 40 psi - 100 psi.
