Voltage and Current Signal Conditioning

Signal conditioning unit measures the current based on the shunt resistor and measure the voltage based on the potential divider circuit. The two level amplification helps the user to customize the amplifier gains.

 

Measurement range

  • Voltage: 10 to 1000 Vrms
  • Current: 10 to 100Arms 
  • Type : AC and DC

Channel availability

  • 2 Channel
  • 4 Channel
  • 8 Channel

Applications

  • Motor drives.
  • Frequency Inverters.
  • Uninterruptible Power Supply.
