I. IntroductionKQC-C2 overload limiter is a new type of smart weight overload protection device, which measure the loaded weight's change by load cell. KQC-C2 could display actual load. When the load reached a rated load setting value, it will show the signals with sound and light, and giving the value of output for switch signal.KQC-C2 contains a series of advantage: rational structure, easy installation and debugging, reliable working and high precision and so on.Using a single load cell is for the tower hoist, windlass and so on; Using two load cells are for the building hoist.II.Technical ParameterWorking power:AC220V/50Hz;Total error:≤5% F.S;Excitation:DC5V;Relay output capacity:10A/250VAC;Input signal:0mV--15mV;Max input signal:≤15mV;Display digits:4 bits;Working temperature:-20-60degree centigrade
