I have had the cameras able to turn on with more than 500mA with no probs, but now, they just do not turn on when there is more than 500mA available. Milliampere to Ampere Conversion Table How to Convert Milliampere to Ampere 1 mA 0.001 A 1 A 1000 mA Example: convert 15 mA to A: 15 mA 15 × 0.001 A 0. I have used a cheap made in hong kong china Power Supply with 16 channels, with a total of 6 Amps and the cameras do turn on. This is really an odd situation, because I have tried plug in power supplies and I have been able to switch on the devices before but now, for some reason fuses are blowing up on the panel and there seems to be a short on a few of the channels, Another issue is that I have one starlight dome which does turn on when connected to this panel, and for this matter I believe which is odd, because starlights only need 190mAmps but then again, Starlights having their own power regulation circuitry, whereas the mini domes, although also using Sony Chips are unable to negotiate with 500mAmps +. I believe at this stage the problem is I have too much current going through the cameras.įor instance, the 12 Mini domes, each dome is rated to take around 300mA to work, and the power supply is a 8amp 9 Channel and even though I double or triple up on each channels, it seems to be consistently delivering 1amp through each connection, and my cameras, through observation is not turning on. One milliampere is equal to 1/1,000 of an ampere, which is the electrical current equal to the flow of one coulomb per second. I have installed around 12 Mini domes + 4 other cameras plus around 5-6 Audio mics for a large Sydney restaurant and I have been unable to get the Cameras to power up. Just to expound a lillte for the the OP: The lower the resistance of the build (when using a mech mod) the more power drawn from a. amp hours is one of the most basic questions asked of cordless tools. Use this calculator to determine the current in microamp, milliamp or. I've installed several dozen, or close to a hundred cameras, and now I have come to my greatest challenge. Sgt.Rock said: Milliamp Hours is the storage capacity (ie: 1000 mah 1 amp for 1 hour) Amp rating (continuous and surge) tell how much power can be supplied at any given moment. I (A) V (V) / R (), which means that the current in amps is calculated by.
