DELTEC 1000 Amp 50 Millivolt Shunt
This 1000 amp 50 millivolt DELTEC ammeter shunt is a very low-resistance connection between two points in an electric circuit that forms an alternative path for a portion of the current. This Shunt voltage drop is used in conjunction with an ammeter to measure amperage of a circuit.
Operation
Continuous
operating current should not exceed 2/3 ammeter shunt rating. To ensure proper operation the shunt
temperature cannot exceed 145°C, as a permanent change in resistance will
occur.
I.E. If continuous current for an
application is 500 amps, the ammeter shunt rating should be no less than 750
amps. This applies to both 50 and 100 millivolt current drop. To estimate
minimum standard shunt rating required, divide continuous application amperage
by .6666.
Amp to
Volt Relationship
Deltec DC
ammeter shunts are listed by Series Type, Amperage and Voltage Drop.
I.E. an MKA-100-100 is a lightweight
shunt, which will drop 100 millivolts at 100 amps with Deltec standard accuracy of plus or minus 1/4%. 66 continuous
operation amps is acceptable for this shunt.
100
millivolts = (1/1000)*(100) Volt = .1Volt
50
millivolts = (1/1000)*(50) Volt = .05 Volt
Estimating
Resistance
To estimate
resistance of a Deltec Ammeter shunt one needs to apply ohms law (1amp X 1volt
= 1watt). For example, an MKA-100-50 has an approximate resistance of 0.0005
Ohms. This is determined by V/I=R. (.05 V)/(100 A) = (R).
