Sensors

Per applicazioni di sub-metering, net-metering, gestione dell'energia e contratti di rendimento, il sensore trasduttore WattNode 208-240 VAC a 2 o 3 circuiti ramificati funziona con i trasformatori di corrente CA Magnelab e un adattatore di ingresso a impulsi o una porta di ingresso a impulsi HOBO Data Node per fornire i veri kilowattora RMS di energia utilizzata, anche per carichi con forme d'onda non sinusoidali.

Overview

Provides accurate kWh measurement at a low cost to meet your needs for sub-metering, net-metering, energy management, and performance contracting applications. This WattNode kWh Transducer works with Magnelab AC Current Transformers and a Pulse Input Adapter or a HOBO Data Node pulse input port to provide True RMS kilowatt hours of energy used, even for loads with non-sinusoidal waveforms. Because these sensors tie directly into the line, they should only be used by qualified personnel. This model supports up to 3 separate 120 VAC single-phase branch circuits or individual 120 VAC phases of a 3-phase wye-connection 208/240 VAC circuit.

Features

Measures up to 3 separate branch circuits simultaneously, reducing complexity and cost
Use with wide choice of current transformers (sold separately); ratings from 5 to 1500 amps
Accurate measurement of multiple single phase or each phase of 3-phase configurations
Easy to install and wire
Individual pulse outputs for each circuit, compatible with pulse input logger models
Small size: can be installed in existing service panels or junction boxes
Diagnostic LEDs: confirms proper installation for all phases
Line powered: no external supply required
Detachable terminal blocks: easy to install and remove
