Murata 2-Wire Voltmeters Digital Panel Meters
Murata Power Solutions digital panel meters are the optimum solution for applications requiring a precise digital readout of ac or dc voltages. AC-input options include average or rms-responding inputs. "Self-powered", 2-wire models contain only two connections. They are powered directly from the same signal they are measuring, making them ideal for new installations or as modern replacements for analog panel meters. Available display options include 3½- or 4½-digit LED or LCD displays that can be operated from ac (85-264V) or dc (+5V to +40V) power sources. Super-bright, daylight-readable LED displays are suited for outdoor applications, automatically adjusting their brightness for comfortable nighttime viewing. Typical mounting options include 12-pin dual inline packages that can be pc-board mounted, and traditional bezel/case assemblies that simplify panel mounting. For harsh environments, choose from several bezel options.
