Voltage ammeter panel mould

voltage ammeter is a can in voltage,current,power,charging
capacity,time and so on many kinds of physical measurement at the same time, also
can set parameters realize over-voltage protection, over current protection,power
protection, charging capacity protection, limited protection and voltage protection
and so on many kinds of protection function in one of the powerful measurement and
control instruments. The instrument used fluctuation two group LED digital display
tube and the test data, and can be used in flexible switch show different physical
quantities. So the meter is very suitable for need to output voltage current monitor, as
well as the battery and discharge applications.

Feature:
According to the measuring current size can choose different models
Voltage current double shows, at the same time also can switch display power,
charging capacity and time
Voltage current double shows, at the same time also can switch display power,
charging capacity and time
With P series end with output shut off function keys, flexible open or shut off
output
Very flexible online calibration function, the user may itself calibration voltage
current value
Four LED digital tube, three measured values a unit instructions
With pressure, owe pressure, flow, a power, charging and exceeds the protection
function

This series of voltage ammeter 10 optional model,The user can choose according to
different needs,pecific meaning as below:
voltage ammeter

1)VAM4020:40V20A,Don’t protect USD15.3
2)VAM9020:90V20A,Don’t protect USD16.3
