Not everyone makes a killing on ebay. Its a datasgeet supply, but regulated, much heavier than switching supplies, they often have a crowbar short circuit protection, also you notice there is 2 terminals for each output, if you have a long run to feed the load, you use 4 terminals instead of two and take a pair to the load to sense the voltage drop and the output will increase accordingly.

I think Max is right. I’ve seen those used in power supplies with 20 or more amps of output, and you wouldn’t even see the voltmeter budge between no load and full load. Back datazheet home page. See terms – opens in a new window or tab. Now that I have this manly 24V power supply with all that extra oomph available, if I wanted to use it for the contactor coil only needs to supply mA for that what would be needed for it to supply 12VDC for my cooling fans, the B.

Turns out my ammeter lead hookup was, uhhhh, flawed and I only need.

The two big precision power resistors off to the left are for that. Have one to sell? United States and many other countries See details.

They tend to develop an intermittent, which will throw things out of kilter- enough at times to cause damage in the supply, not to mention whatever load is attached. Go bad in 3 to 4 years if not faster. To use remote sense you run two extra wires from the power supply to the load, they are normally very small wires as they don’t provide power they just measure the voltage at the distant end. Nice score – I much prefer linear supplies to switchers, for one thing they don’t wipe out radio reception in the Shed Of Danger The worst problem I see in any adjustable power supply is with the adjustment pot itself.

Milton, The transformer is typical of that in a linear power supply.

Perhaps a small CNC device with some of the little stepper motors I’ve got ratted away around here somewhere Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag.

The reason the leads are so long is they will generate some heat at full current draw, so they want to get them off the board. Very simple to do and you end up with one supply source for all the control, and if they do not require regulation then simple bridge and caps are all that are needed.

Actual numbers may vary depending Operating Junction Temperature Tj: So a single 36 Ohm, 8 or 10 Watt resistor will allow you to operate that coil.

At low frequencies you need more iron than at high frequencies. Regardless, this is probably the best preventive maintenance you could give that power supply. Linear meaning that everything happens at line frequency, 60 hertz. If you’re considering PC power supplies, be aware that the newer ATX supplies need a couple of leads loaded to get the main 5V and 12V supplies to datssheet in VR1 is marked O.
