I was sent a power supply for a unit that requires 9 volts DC with
180ma.
The power supply says input 220v AC, not 110-220v, so I guess that
means non switching, and is supposed to supply 300ma of current. . I
checked the voltage output and it is 9.5 volts, so I'm good with that,
but I do not have an amprobe, so I couldn't check the current.
Basically the power supply does not have enough "juice" to power the
unit (a CCTV camera).
Here is the question. Since I can't check the amperage from the
power supply, could the fact that I'm pluging it into 110v and not 220v
be the reason that I am having a problem? What would the amperage
output of the unit be? Is there a conversion formula? Is it half?
It appears to be the situation. Thanks in advance.
