24 VDC 6A 145W Regulated Switching Power Supply

can i use two of these and wire the output in series to get 48VDC?

Asked by: calicchio
Possibly. I have had situations where I used 2 switchmode supplies in a bipolar configuration with one supplying the positive voltage and the other supplying the negative voltage. The supplies were connected together with the - of the positive supply connected to the + of the negative supply and this connection became the common connection for the amplifier circuit. When I went to power it up, one of the supplies would not "start". Both would start up fine when powered individually but they would not run together. The best explanation I could come up with is that the two supplies start up at slightly different speeds and the one that wouldn't start was seeing a "negative impedance load" (a reactive dynamic impedance if plotted on a polar impedance graph) that was hanging the short circuit protection of the non-starting supply. The power supply manufacturer was aware of this issue but had no answers for me. I don't know if you would have such a problem running two switchers in series like this, but I just wanted to put the word out there that there "may" be issues when running switchers in series. Buy a 48 Volt supply if it is 48 volts you need.

Can this be powered with a dc to ac converter?

Asked by: owniecogs
Theoretically it can be powered by a DC to AC inverter. The big question here is whether the inverter can supply the startup current needed to "start" the power supply. My experience with switching power supplies tells me it "might" work. From your related product info I would guess that you're trying to get from 12 volts to 24 volts in a mobile application. Going from 12 volts DC to 120 volts AC and then back to 24 volts DC comes at a huge cost in efficiency. For every ampere you draw from the 24 volt supply, the 12 volt supply will have to provide 3, 4, 5 or more amperes, maybe more. If I were doing this, I'd be looking for a 12VDC to 24VDC converter. It won't be cheap but it will be much more efficient. If it's an amplifier that runs on 12 volts you need, I'd buy a car amp, which has the step-up power supply built in already. Hope this helps.

instructions?

i would like to get one of these sure boards,but i dont quite know how to hook it up. Do these come with a manual?
Asked by: 110volts
If you asking about a manual for the amplifier, its available on the store web page or from the manufacturer which there is also a link to from PE. You need to get a pig tail barrel plug and simply connect the ends to the PS then plug it in, make sure u have the gain all the way down at first test as there is no volume all sources have different output voltages and impedance.

Can I use this PSU to charge 2 12V SLA Batteries?

I realize SLA batteries need some sort of monitor, could I put some sort of monitor in between this PSU and the batteries? a series of resistors?
Asked by: Leejin
There is alot more needed then just some series resistors to properly charge SLA batteries. Charging current should not exceed C/3 (1/3 capacity of battery), so for those 5Ah batteries you listed the charging current should be less then 1.6A, and lower charge rates are better for battery health. This power supply can produce currents far exeeding what the batteries can handle.For SLA batteries maximum charge voltage is also a concern as the resistors will not limit the voltage. The maximum voltage a SLA battery should reach under full charge is 14-14.4V depending on the type of charge (shunt vs PWM/linear). The voltage may not be a problem with this regulated supply if you have batteries in series, as it may not even produce enough voltage to fully charge the batteries when in series. Depending on the no load voltage of the power supply (if right around 24-25v) you may not even get past a 20% state of charge, very bad for the health of any type of LA battery.

Can it be used to power the 1A Bluetooth Receiver?

I am using this power supply to power one of the Sure Amps. Working great. I would like to add the BT-1A Bluetooth Receiver Module, to the current setup that I am using. The question is can I power the 1A Bluetooth Receiver from this power supply? What would I need to do to do so? Is it as simple as cutting off the USB off and connecting to the power supply output? Or would this just burn it out?
Asked by: GAHope
You will need to use a regulator of some sort to drop the 24 volt output of the power supply to the 3.3 to 5 volt supply required by the bluetooth module. If you wire the module directly to the 24 volt supply it will be damaged. Look into using a 5 volt regulator similar to an LM340-T5 or a 7805. You'll need a heatsink for the regulator as you'll be asking it to disipate the 19 un-needed volts at whatever the supply current is. The regulator may get a little warm.

How to connect?

So this is my first time build. I'm trying to acquire all the needed parts, and of course a supply is a big one. I understand how to hook up the power (L,N,Ground), but how would I put this on an amplifier? And then consequently, If I wanted to attach a external power switch or an LED light, how would I attach thouse as well? What are the COM and V+ connections?
Asked by: JacobNSullivan
The answer to all of your questions is "It depends"......on how professional and fool-proof you want your final product to be. I can tell by your questions that you are VERY new to this. If you want the cheapest fastest and ugliest design - you just get a piece of plywood about 18" by 12" and nail or screw all the parts (pwr supply and amplifier modules) to it. All the wiring shows and little kids should never be allowed to touch it EVER. If you don't want to do that - you willl need to either buy a chassis box or rip all the guts out of an old receiver to use it and the switches, power cord and speaker terminals.Regarding the COM and V+ connections - if you do not know what they are for yet - you do not have enough knowledge (yet) to build anything. They are the SINGLE ENDED power output for the amp modules - and if you do not know what that means - there is a 50/50 chance that this power supply will not work wth the amp modules you may buy. You need to either do a lot more reading about this OR buy a complete kit (amp modules, power supply, chassis). Don't worry - this is how I started.....many years ago.....you learn a bit with each project. If I were you and did not want to waste money blowing up stuff to learn what not to do - I would buy a kit figured out by Parts Express.
