The DC model covers the range of 6 to 75V and the AC model covers 85 to 264 VAC, 47 to 63 Hz. The meters are fully operational— no additional components or power sources are required. The meters are housed in rugged, round polycarbonate cases that provides excellent protection against moisture, dust, shock and vibration. Panel installation is straight forward: using readily available tooling, simply drill and punch a 1.2 inch (30.5mm) diameter hole and anti-rotation notch, insert the meter and gasket into the panel, and securely fasten the meter using the supplied hex nut. The supplied hardware is designed to provide protection to IP67/NEMA 6 ! FEATURES Self-powered, requires only two connections Installs in round “oiltight” 1.20 inch (30.5mm) cutouts Four-digit LED display with overvoltage indication Digital replacement for analog panel meters Screw-style terminal block simplifi es installation Provides moisture resistance to IP67/NEMA 6 Supplied with EPDM rubber gasket and plastic hex nut Panel knockout punch available To place an order, enter the quantity of desired items and then click on the bar at the bottom of the chart.
