A. Selco/Asahi offers meters with all of the below operating power requirements. 110 (VAC domestic) 220 (VAC off shore) 9-32 (VDC battery or reduction) Loop (Best to eliminate noise) Many Power supply options are available. The most common are 110/220 VAC and 9-32 VDC. Loop powered meters derive power from the 4-20mA loops they are monitoring, requiring only a small voltage drop. Loop powered systems are ideal for noisy electrical situations, as the system is closed from external power lines running to it.
