Current Viewing Resistor (CVR) is a high quality current detection resistor (high frequency resistor) that is expected to be used in the technical and technical fields such as automobiles, aerospace, and submarines.

Designed to maintain very high peak power and current input caused by capacitor banks, pulse generators and steady state current loads. The linear response in the wideband bandpass provides an accurate indication of current without inductive components.

Assumed application examples :
SCR current measurement / Automatic welding machine current control / Automotive alternator output measurement / Fault current detection to determine bearing wear of main turbine generator / EBW test / Current detection in explosion system / Transmission substation Phase fault test / Modulator fault detection / Laser system current measurement / Electric vehicle chopper current control / Circuit breaker test… etc

Many models of Current Viewing Resistor (CVR) are prepared according to factors such as application / resistance: Ω / band pass: Mhz / rise time: millisecond / Emax: joule. For the model lineup, please refer to the following web page together with how to select which CVR is suitable.
