Win a Tenma Power Supply

Electrolysis, electroplating, load calculation, battery charging, there are lots of uses for a very stable reglauted power supply!

This Tenma power supply would not only be handy as a hefty paperweight to keep those all important datasheets and service manual pages from flying around, but also for charging batteries, electroplating metals, electrochemical corrosion/rust removal, testing faulty equipment, cooking hot dogs by conduction, heating a hotwire cutter for polystyrene or a resistive tip for woodburning, powering a slotcar set, as a low voltage lighting dimmer, run a computer fan to keep me cool at my workbench, heat ballast resistors to keep me warm at my workbench, hm,p both at once to act as a fan heater, powering a pair of USB heated socks ... and supplying a peltier plate to keep my tea warm - or my beer cold.

A clean and powerful power supply is a dream for audiophiles. So how about using this kind of bench-top power supplies to replace those Hi-Fi power supplies that cost more than a few ten thousands?

Late for theme Energy Harvest , but still slow in progress  The specified item was not found. .

There is no new use of Power Supply. Challenging part is how to set the parameter on RF transmission line and antenna. Measuring power efficiency and output curve may need the Power Supply.

Still like to see other innovated use of this power bench.

A new dual output digital power supply is a useful item. I have many uses for something of this type.

     Call me crazy or what, but I have a plan. I would like tho take the output of two or more channels and measure the ripple using a MCU with ADC taking up to 12.5 mega-samples/second using 12/16 bit samples. Overtime these will vary according to the ripple in the power supplied by the Tenma power supply. The result can be compared to the channels used from the Tenma power supply. I plan on using a sigma delta filter module to sense the current flowing. By varying the current, I can see how the ripple fluctuates from a low level to a higher level. This can be very instructive on usage of the power supply choices of current vs voltage in projects in the future.

Connect the power supply to a power resistance, and warm up your legs.....winter is coming

Cool contest! I like the novel uses some poeple have suggested

I would suggest it could be used to gold (or silver) plate probe tips / contacts via electrochemistry to take advantage of the low contact resistance gold plating provides and give us more precise measument ability, but I see someone has already suggested using it for copper plating which is very cool too. Similar to this is electrically anodising titanium or aluminium to help prevent galling from metal to metal contact between bearing surfaces (or purely for cosmetic reasons to colour it!).

My suggestion instead is to use it to be able to test low resistance values in cables or in circuit non-destructively. A good example of this is testing shielded cable to estimate percentage braid coverage or the gauge of the drain wire. If we measure the current in series with our device under test and measure the voltage drop across it, after plotting our readings for several supply current and voltage combinations, we can produce a quite accurate estimate without having to do destructive testing or 4 wire measuments.

Thanks for reading,

Hi all,

this Tenma power supply does not have a very important futures like FORCE&SENSE.

When the power supply can delivery high currents (like this!), it is very important to enable the SENSE input otherwise you risk to have an invisible bad connection and your DUT does not work.

The SENSE feature is a must in the semi-professional and professional equipment.

This is my opinion and I hope to be useful to my colleagues who are choosing a new power supply,

Best Regards,

Fulvio

I would burn electronic components with it, maybe try to melt something using graphite electrodes. (since it's free)
