The CUB4 volt and current meters are designed and manufactured using the latest technology for a high quality, compact, affordable instrument for use in industrial environments. Each unit has a 31/2-digit LCD display with 0.6 inch (15.2 mm) high digits and a DIP switch selectable decimal point. The displays are available in positive image reflective (black digits, reflective background) or negative image transmissive (illuminated digits, dark background) with red or yellow/green backlighting. The units are constructed of a lightweight, high impact plastic case with a clear viewing window. The sealed front panel meets NEMA 4X/IP65 specifications for wash-down and/or dusty environments, when properly installed. A CUB4V or CUB4I unit can be mounted in the same panel cutout as the CUBVD and CUBID units. The optional Micro line/sensor power supply (MLPS1000) is designed to attach to the rear of an installed CUB4V or CUB4I to provide the necessary power for the unit. The optional supply can be powered from a 85-250 VAC source.
