T-WNB-3D-240 Sensor

Product catalog summary

Product Overview: The T-WNB-3D-240 Sensor is a WattNode 208/240 VAC 3-phase Delta/Wye kWh Transducer Sensor designed for sub-metering, net-metering, energy management, and performance contracting applications. It provides accurate kilowatt-hour measurements even for non-sinusoidal waveforms and is compatible with Magnelab AC Current Transformers and a Pulse Input Adapter.

Key Features:

Supports 1, 2, or 3-phase measurements in 2, 3, or 4 wire configurations.
Compatible with a wide range of CTs (5 to 1500 amps).
Easy installation and wiring with detachable terminal blocks.
Pulse output compatible with pulse input logger models.
Small size for installation in existing panels or junction boxes.
Diagnostic LEDs for installation confirmation.
Bidirectional metering for solar and wind power generation.
Line powered, requiring no external supply.
UL, cUL Listed and CE Mark certified for safety and use in North America and the EU.

Specifications:

Operating voltage range: ±20% of nominal.
Frequency: 60 Hz.
CT input: 0-0.5 VAC operating, 3 VAC maximum.
Connectors: UL, CSA recognized, detachable screw terminals (14 AWG), 600V.
Operating temperature range: -30 to 60°C (-22 to 140°F).
Operating humidity range: 0 to 90% RH, non-condensing.
Dimensions: 8.5 cm x 14.3 cm x 3.8 cm (3.3 in. x 5.6 in. x 1.5 in.).
Weight: 295 g (10.4 oz.).
Number of data channels: 2.

Catalog excerpts

The WattNode provides accurate measurement at low cost to meet your needs for sub-metering, net-metering, energy management, and performance contracting applications. This WattNode Delta-connection kWh Transducer works with Magnelab AC Current Transformers and a Pulse Input Adapter 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 be used only by qualified personnel. This model supports a 3-phase Delta-connection of 208/240 VAC. Supported Measurements: Kilowatt Hours (kWh) Key Advantages: • Measures 1, 2, or 3 phases in 2, 3, or 4 wire configurations. • Use with wide choice of CTs (sold separately),ratings from 5 to 1500 amps. • Accurate measurement of 1-,2-, or 3-phase configurations. • Easy to install and wire. • Pulse output - 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. • Bidirectional metering - Net metering for PV (photovoltaic) solar and wind power generation with only one meter. • Metering of variable frequency drives. • Line powered - No external supply required. • Detachable terminal blocks - Easy to install and remove. • UL, cUL Listed - Designed and tested for safety and use throughout North America. • CE Mark - Can be installed throughout the EU.
