Versatile AC digital power meters. The design of POWER fills the need for a high accuracy digital switchboard meter with transducer outputs that can be configured in the field by an end-user, or when installed in new electrical equipment by an OEM.
It eliminates requirements for a large inventory of dedicated instruments, and provides flexibility when new panel designs or system upgrades require changes in instrument transformer ratings. Our rugged metal case fits standard panel cutouts for switchboard meters and makes it a perfect replacement for less versatile instruments. They can also replace separate power transducers and meters in new equipment designs. An overall good solution for reduced wiring, panel space reduction, improved accuracy, and lower cost.
• Scaling for PT (potential transformer) primary ratings up to 1250:1
CT (current transformer) primary ratings up to 5000:1
• True RMS current and voltage measuring capability
• Accuracy: + 0.2% of reading; + 0.1% of full scale
• Settings stored in non-volatile memory and retained through loss of power
• Electrical legends (Watts, Kilowatts, Megawatts) can be set by user and indicated by a red LED adjacent to the legend
• Adjustable transducer output proportional to the primary input setting
• Display average setting: "rolling average" of inputs reduces "digit bounce"
