What’s new with PowerHalt?

PowerHalt PH3 R or W-Terminal kit – This kit is an addition to the PH3 system that utilizes a Variable Reluctance (VR) sensor to read engine speed to determine proper and safe shut down event. Alternative to a VR sensor is to measure on the R or W-Terminal on an automotive engine’s alternator stator tap. The output is used as a tachometer signal with AC voltage waveform similar to that of a VR sensor. The benefit of using the alternator output reduces the need for an external sensor, as the installation process is greatly simplified.

Power Take Off Kit – This kit provides a secondary pre-set speed for Power Take-Off (PTO) applications. Providing ground to the PTO input allows users to engage a second emergency shut-down speed for while powering auxiliary equipment. To prevent accidental shut down while enabling and disabling PTO, a 5 second grace period is applied when switching to a lower threshold, to allow for engine speed to reduce. When switching to a higher threshold, the threshold change is applied immediately.Applicable for PH3 product line.
