It is capable of accurately measuring quasi-sine AC source such as modified, modified 2-step and modified 3-step sine wave in addition to conventional sine, triangle and square wave inputs.
The voltmeter fits an industry standard “oiltight” 30 and 30.5 mm / 1.2 inch round panel cutout. The 7.6 mm / 0.3 inch four-digit LED display is housed in a rugged round polycarbonate case that provides protection against dust, moisture, vibration and shock. It is supplied with an EPDM rubber gasket and plastic hex nut that aid protection to IP67 / NEMA6 specification for water ingress.
The DMR20-1-ACV is ideal for measuring the AC line voltage of a wide range of applications such as primary line power, power distribution units and backup power generation sources. The voltmeter consumes a maximum of 30 mA when used at 250 VAC / 60 Hz.
Round knockout punch tooling can be ordered with the DMR20.
