An AC-DC power supply is used to supply 24 V DC to the IS1001-MC or IS1001 when 120 VAC or 220 VAC power is available. The power source must be isolated from other systems to minimize the potential for performance degradation due to conducted electromagnetic interference (EMI). A Battery Switching Power Supply can be used to isolate the detection system from EMI and provide a day or so of autonomy. Interested in finding out more information on the Grid Power system?
