The AQ-101S arc point sensor device is a sophisticated microprocessor-based arc flash protection unit for arc light detection. It is designed to minimize the damage caused by an arcing fault (arc flash) by tripping the circuit breaker that sources the fault current. The complete system self-supervision function of the AQ-101S arc point sensor device provides the highest level of dependability by continuously monitoring all internal system functions as well as external connections.
A wide range for the power supply (18…72 V DC or 92…265 V AC/DC).
A maximum of 12 arc light point sensors (3 point sensors per channel).
4 trip relays (with 7 ms trip time).
1 system failure relay.
3 fast binary outputs.
6 fast binary inputs.
1 multifunction push button.
17 indication LEDs.
