Hi I want to use your 12V 10A power supply to power a car radio I have in my garage. Is this supply designed to be plugged into a 110V wall receptacle 100 percent of the time, even when the radio is turned off and drawing no power? Also what is the power supply current draw when it is plugged in but not supplying any power? Thanks Richard
Hi.. The 12V 10A Power Supply is Ideal for powering a car radio at home. Please make sure that the total watt usage of the car stereo is not more than 120W, which is the maximum load possible for this power supply. If the radio is turned off the power usage is almost zero. The power supply only turns on when there is a load on it... So you don't have to worry about the power supply passively using power.
I have a Relaxzen massage/heat chair, looking for replacement power adapter, any suggestions as to th right one?
Hi Ramon. I can't do all your research for you in relation to finding the power supply, but I can give you some hints.. The easiest way is to find the old or broken adapter for the device you want to power and look at it for the details. It will have the voltage as well as the amperage printed on it. So if it says 12V, you will need to use a 12 Volt power supply. The voltage has to be an exact match. The amperage will be shown either as A for Amps, or W for Watts. For this, you need to find a power supply that can supply the same, OR MORE, than what the current power supply indicates. So if the old power supply says 2A, you can use a 3A or a 4A, or even higher. If there is no amperage indicated on the old unit, there should be a wattage shown as "W". To get Amperage from Wattage, all you have to do is divide watts by volts. In this case you would divide by 12, So if the 12V power supply is 60 watts, that would be 60 W divided by 12V, which is 5A... So you would need a 5A or higher power supply. The other thing to check on the old power supply is the type of connector. All our power supplies have a standard DC connector. It is a barrel connector with an outside barrel of 5.5mm, and and inside barrel of about 2.5mm. If the old power supply has a non standard connector, square, or multiple pin, then you will need to order the universal power supply we carry, which has a set on interchangeable connectors so you can find one that matches your device. I hope this helps.
I just purchased a home siren (DSC SD30W). It claims to need 6-12v DC 1100ma, and it is also referred to as a 30 Watt siren. I can find 12v DC 2amp or greater, but many say max watt output is 24, or don't say at all. What adapter will work for this thing? Thanks
Hi Dave. If you device is 12 Volt, and it uses 30W (watts), it will need a power supply that can handle a load of 30 divided by 12, which is 2.5A. In this case you can use an power supply of 2.5A or higher. I recommend that you use a power adapter of at least 3A to make sure you are not running it at it's maximum capacity. Let me know if you have any other questions.
This article deals with the special considerations you must make when you are choosing a power supply for a a DC motor. These special considerations require an understading of continous vs peak draw, and how they effect any specific 12V Power Supply.
