    D.C. Shunt
    D.C. Shunt
    The D.C. Shunt (or ME shunts) available with us are ideal for current ratings from 5 to 10000 Amps and mill volt drops of 75 millivolts. The product conforms to IS Standards 1248 and is provided with leads of 0.025 ohms. Some of its construction features are cited below:
  • It consists of Mangenin rods, soldered or silver brazed, to brass end blocks.
  • It is artificially aged after manufacture; followed by tests on full load.
  • Lead resistance is considered while calibrating the instrument
  • Salient features of the ME Shunts are as follows:
  • Class 1 accuracy
  • Temperature Co-Efficient
  • 0.002% per degree centigrade, above ambient temperature in still air, with free ventilation
  • Temperature not exceeding 120°C at the center and 90°C at the ends
  • The ME Shunts withstand temperatures up to 120oC; without any permanent alterations in physical or electrical properties
  • Overloads and faults due to high temperatures (>120oC) can be safely handled
  • All 75 millivolts drop shunts of class 1, withstand the following overload requirements:
  • 2 X rated current for 3 minutes
  • 4 X rated current for 30 seconds
  • 10 X rated current for 5 seconds

    Load Bank
    Load Bank
    We manufacture and export high class ME Load Bank, which is a single phase and three phase variable Lamp or resistor or capacitor load and is housed in a metal case. It is used for stimulating load conditions to test Voltmeters, Ammeters and Watt meters, using load switches provided on the bench. The total simulated load is the sum of loads of all 'ON' switches. Construction Features: The ME Load Banks are provided with:
  • Castor wheels for easy handling
  • Ammeters and Voltmeter on front panel to indicate the current and voltage respectively
  • Heavy-duty Porcelain switches with bake lite top and inner brass contact for safety
  • Specifications:
  • Input main voltage: 230/440vac.
  • Voltmeter range: 0-300/500v ac
  • Ammeter Range: 0-5/10/15/25aac
  • Load range: 1/2/3/5/10 kw
  • Load type: Bulb / Resistance / Capacitor / Induction Load
