A new low power "Fail-safe" vehicle detector that is perfect for solar powered safety loop installations. This detector is the low power version of our DSP-7 detector.

This detector beats all competition for low current consumption.
 Less than 1 mA without a vehicle and approximately 23 mA with a car on the loop.  Just like the DSP-7 and the DSP-6LP, it operates on any voltage from 10 to 30 volts AC or DC
