شنت جریان DC مستقیم 50 آمپر

برای اندازه گیری جریان بالای DC در مدارات جریان مستقیم ، از شنت با
کلاسهای دقت 0.5 و 1 استفاده می شـود . این شنت دارای کلاس 0.5 و تبدیل افت ولتاژ
75mv میباشد.

شنت DC ، جریان بالا در مدارات DC را به افت ولتاژ
متناسب با شنت تبدیل کرده (50mV/60mV/75mV/150mV) که می توان به ولت متر های DC که جهت اندازه
گیری جریان بالا در مدارات قرار گرفته است ، متصل نمود .

 Based on the various questions that
customers often have, the following summary references are made:

Note: A meter with
a range of 50A or 100A must be connected to the shunt
to measure the current regardless of whether the measured current is less
than 10A ! Otherwise it will burn out the meter.

The voltage is normal and the current
is 0.00 or 0.0.

Make sure that the thick black wire is connected to the negative
pole of the battery and the thick red wire is connected to the negative pole of
the load. (Note that the discharge is not the same as the charging wiring,
see the concept of load and power afterwards .) (Meter
using imported chips, through a very rigorous testing and calibration to ensure
the factory . No quality issues before shipment. Meet current
display 0 cases of 99.99% is wired wrong, please be patient
carefully check the wiring)

Current display is not allowed

If it is directly powered or the independent power supply is
co-located with the equipment power supply, as long as the thin black line is
disconnected, it can be accurate.

Connected to the power supply does not display

Any AC power that has been rectified must be filtered by an
electrolytic capacitor of 1000uF or more to supply power to the
meter.

Judging whether the header is good or bad (the following are the
two cases of the normal header)

Without the shunt, connect the thin red line and the thin black
line to the power supply, the meter current of the range
of 50A shows 50.0~59.9 , and the meter with the
range of 100Ashows 100~109 ;

Connect the shunt, connect the thin red line and the thin black
line to the power supply, the meter current of the range
of 50A shows 0.00 , and the meter with the range
of 100A shows0.0 ;

Other considerations

The current can only be measured in the negative pole of the
power supply and the negative pole of the load.

Voltage range: The power supply voltage range of
the 5 lines is4~28V , that is, the voltage of the thin red line
cannot exceed 28V .

Concept about load and power

When discharging: The battery, switching power supply, and
transformer are the power supplies. The resistors, lamps, motors, and devices
that use electricity are loads.

When charging: charger, generator, solar energy is the power
source, rechargeable battery, battery is the load.
