We develop and manufacture current sensors, mainly including current switch, current transducer.

Current Switches
The Series are intended to monitor the operating status of fans, pumps, and motors. These self-powered switches can be hung or tied directly to cables or wires. For use on existing installation, split core models can be installed without disconnecting cables. LED indicators provide a visual confirmation that the current is passing through the core. Both fixed and adjustable set points are available. The adjustable models easily adjust the set point with a potentiometer.

LED Indicators
Green LED: indicates that current is passing through the core, but the set point has not been reached and the contacts are open.

Current Transducer:
Three ranges per unit reduces inventory by selecting jumper or none. No field adjustment necessary, factory calibrated. Average measurement is equivalent to True RMS for pure sine waves for the 0-5V, 0-10V no need power supply. 4-20mA series True RMS measurement for sine waves or variable frequency drives for the series Input or Output isolation through current transformer solid-state reliability.
Approvals: UL & cUL CE & Rohs.
