Amper (A)

How can you use this tool?


Especially in the planning of camera systems, since the current or the power consumed by the cameras is known, it will help you in selecting the appropriate adapter or transformer by calculating the power or current that the whole system will spend. Do not neglect to be tolerant.

Watts = Ampere x Volts (W = I x V)

For example;

  How many amps of adapter is required to operate 5 SNB-6004P cameras centrally with 12VDC Adapter?

As you can see from the data sheet of the product, the camera's power consumption is 4.2W. 5 * 4.2W = 21W total power is needed. When V = 12, W = 21 are entered in the calculation tool; An adapter of 1.75A will suffice for the operation of this system.
