The L18P series open loop hall effect current sensor is available in 10 rated currents ranging from 3A to 60A & PSU options of +5VDC, +12VDC, and ±15VDC. The features include single and dual power supply operation, good accuracy (~ 1%); and fast response time (≤ 5µSec). The L18P series is PCB mounted with a multi-turn integrated primary conductor rated for up to 30A and a  bus bar configuration rated for 40A – 60A. The L18P series, as with other open loop current sensors, has an instantaneous voltage output. The output of the L18P***D15 current sensor is 4V at rated current, whereas the L18P***S05 & L18P***S12 output consists of the zero offset voltage of 2.5VDC + 1.5VDC at rated current for an instantaneous output of 4.0VDC. The L18P***S05 & L18P***S05 gain can be set to provide an output per the alternate industry standard of 2.5VDC + 0.625VDC at rated current for an instantaneous output of 3.125VDC.
