Electrical / Mechanical |
|
Power Input |
4.75-12 VDC 4 max rating, stabilized to within 10% powering
sensor via Vbat+
5.5-12 VDC 4 max rating, stabilized to within 10% powering
sensor via G+ (on board protection circuits) |
|
Current consumption |
~250A (1 measurement/hour)
~50A in sleep
~60 mA average during active measurement sequence (~12s)
< 150 mA peak current (averaged during IR lamp ON, 100 msec)
< 250 mA peak power (during IR lamp start-up, the first 50 msec)
for maximum operating time (if powered by batteries), choose
batteries that can deliver 250mA pulses without large voltage
drops (for example batteries recommended for cameras) |
|
Electrical connections |
