Sensors

Pour les applications de sous-comptage, de comptage net, de gestion de l'énergie et de contrats de performance, le capteur kWh WattNode 208-240 VAC à 2 ou 3 circuits de dérivation fonctionne avec les transformateurs de courant CA Magnelab et un adaptateur d'entrée d'impulsion ou un port d'entrée d'impulsion HOBO Data Node pour fournir des kilowattheures RMS réels de l'énergie utilisée, même pour les charges avec des formes d'onde non sinusoïdales.

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
