Description

The BKW 4-terminal current sensing precision shunt resistor series from Isabellenhütte has been designed for use in energy meters and other battery management and current sensing applications. These resistors are qualified for 20A, 40A, 60A and 80A energy meters. The BKW series is available with resistance values from 0.0003Ω to 0.0005Ω as well as excellent long-term stability, meaning energy meters do not require any recalibration. Other benefits include very high reproducibility of R-value and TCR.

  • 4-terminal current sensing resistor
  • Resistance values of 0.0003Ω, 0.0004Ω and 0.0005Ω
  • Tolerance of ±5.0%
  • TCR of <±20 ppm/°C (+20°C to +60°C)
  • Temperature range from -55°C to +140°C
  • Constant current up to 100A (0.0003Ω)
  • Inductance of <3nH
  • Massive copper terminals
  • Mounting: screwed on terminals of kWh-meter
  • Qualified for 20A, 40A, 60A and 80A energy meters

 

Typical applications for the BKW current sensing precision shunt resistor series include:

  • Ideal for single and three-phase energy meters
  • Battery current sensing
