LPR - The LPR is an adjustable regulated power supply with a maximum output current of 1 amp. It accepts up to 28 VAC or 40 VDC input voltage and outputs 2 to 25 VDC by adjusting a multi-turn potentiometer. Its compact size allows it to be installed in either 2.25" or 3.25" snap track. Half wave rectification makes it possible to power the LPR from either AC or DC sources. These sources can be either grounded or floating without damage to the LPR.  The LPR is covered by ACI's Five (5) Year Limited Warranty.
