What will happen if use a 12v 400ma instead of 12v 500ma?
i am not sure, BUT according to the answer in this post:Can_you_use_a_9V_600mA_adapter_on_a_9V_400ma_scanneryou need an adaptor of 9v and AT LEAST 500mA (assuming that the appliance draws 500mA)
Can you replace 12v 1a adaptor used on device of 12v 700ma?
No, the new adapter will not be able to safely supply enough current.
What is the size of the ac adaptor for a fiber optic tree?
input 230-240v output 12v-55va
Can a 9 volt adaptor be used on a appliance that calls for 9volt battery or 12volt adaptor?
No. The person who designed your appliance had a 12v adapter, so when he designed the adapter connector he put a resistor in it to drop the voltage to 9v.
Can you use a 12v 500mA switching adapter going to a 12v 700mA security camera?
If the camera actually uses 700 mA in order to do its job, then the 500 mA adaptor will warm up, then overheat, and eventually fail.
Where can you get a Pyramat S2500W Wireless Sound Rocker power cord?
Could someone please tell me what adaptor I will need to buy for my S2500W Wirelss Sound Rocker. It say 12V AC but I do not know the apms. Also where do I purchase this adaptor. Please help
How does a 6volt relay circuit works?
The same as a 12V relay circuit, except it only needs 6V instead of 12V.
Can you use 12v ac 60w instead of 12v ac 2a adaptor?
Probably yes. The 12v 2 amp adapter can put out 12x2=24 watts. The 60w adapter can handle more than twice the power (60 / 12 = 5 amps). However, the voltage of inexpensive adapters may be quite a bit higher under low loads. I'd check and make sure the voltage was not very much greater than 12 volts with a 2 amp load.
Can I replace a 12volt dc 2amp adaptor with a 12volt 1.5 dc adaptor?
by definition the wattage is the criteria 12v x 2amps=24 watts If the circuit in question needs 2 amperes then an exactreplacement mandatory, however if the circuit in question only draws 1.5 amps then it is realistic possible
Can you use 12v 600ma instead of 12v 500ma?
Using a 12v 600ma source is allowing 12 volts and 600 amps of power. If the device requires a 12v 500ma source, the larger source is acceptable. Please note that it will only be drawing on 500ma of the available 600ma.
I need to make a 72VA 220-12V DC Transformer. The drawing gives me 158 lamination and I need to use 133. How do you convert a 158 lamination to 133 lamination?
There is no such thing as a 'd.c. transformer'. If this is a typo, and you really mean an 'a.c. transformer', then the number of laminations will act to reduce the eddy-current losses within the core, but should not affect the turns ratio of your transformer if that's what you are trying to achieve.
How many model rail station 12v lamps can you wire in sequence on a 500 miliamp dc adaptor?
500 milliamp = 1/2 amp. Have to know the wattage of the lamps or the resistance of one lamp to give an answer.
