• 3 1/2 Digit LED Digital Panel Meter
• 5 AC Amperes
• Scaled RMS

The DU-40ACI1 and DU-40ACI5 are low cost, AC current measuring meters with a very low burden of 0.1VA and 0.5VA respectively. Their internal shunt provides for direct connection to 1A or 5A CT’s (current transformers). No matter what the CT ratio, the 15 turn, infinitely adjustable Span potentiometer enables the user to easily scale the output to display almost any current value required. The DU-40ACI1 and DU-40ACI5 meters can withstand momentary over loads of up to 300 Amps (60 times input signal) for one second without developing an open circuit. Our unique differential AC measurement circuit provides high impedance to ground on both sides of the shunt.
