RTC050A current sensor

Product catalog summary

Description
The RTC050A series is a multi-range Hall Effect current sensor utilizing a closed loop design based on the Hall effect and null balance method. It provides accurate electronic measurement of DC, AC, or pulsed currents by outputting a balancing current that mirrors the primary current, reduced by the number of secondary turns.

Rongtoch Industry (ShangHai) Inc., Rongtech <D RTC050A Series Hall Effect Current Sensor DESCRIPTION The multi-range RTC050A series current sensor is a closed loop device based on the principle of the hall effect and null balance method. The output from the current sensor is the balancing current which is a perfect image of the primary current reduced by the number of secondary turns at any time. This current can be expressed as a voltage by passing it through a resister. It provides accurate electronic measurement of DC, AC or pulsed currents.
