Shunt measuring steady 75SHSM3 20A (75SHS-M3, 75SHS M3)
Shunt measuring steady 75SHSM3 20A is intended to limit the extension measure DC ammeters and counters Cove ampere-hours.
Product Specifications stationary measuring shunts 75SHSM3 20A:
Accuracy class 0.5;
The voltage drop across the terminals of the potential for all grafts at rated current is 75mV;
Limits of error of shunt - ± 0,5%;
Rated current measurement shunt product stationary 75SHSM3 20A - 20A;
Nominal impedance - 3750 mkOm;
Maximum permissible variation of the resistance values of the shunt products 75SHSM3 20A measurement is stationary, appearing as a result of termoelektrodvi zhuschey power at nominal load current is equal to half the absolute value of the limit of permissible basic error STI shunt;
Maximum permissible variations in the values of shunt resistance, which has two or more current clips on each side, resulting from the unequal distribution of power in the place of summing up the current to shunt off with one Toko vomu clamp on each side of the shunt is equal to half the absolute value of the limit of permissible basic error;
Shunt 75SHSM3 20A measurement is designed to work steady at approximately rounding the air from -40 º C to +50 ° C and a relative humidity of 95% (at 40 ° C);
Shunts, intended for export to areas with cold-temperate and tropical climates, supplying lyayutsya for operation at temperatures from -40 º C to +50 ° C and a relative humidity of 90% (at 35 ° C) and IME UT designation 75SHSM3 20A and 75SHST2;
The average life of the product shunt 75SHSM3 20A measuring a stationary to write-off - at least 15 years of age.
