WattNode® for Lonworks® Bidirectional Networked Energy Meter by Socomec

Description

WattNode® for Lonworks® Models Bidirectional Networked Energy Meter and WattNode® Logger

• The WattNode for LonWorks is a networked energy meter that measures both energy consumed and energy produced (bidirectional)
• It provides electrical measurements such as energy (kWh), power (kW), voltage, current, kW demand, kVAR, kVARh, power factor, line frequency, etc
• These measurement values are communicated using the LonTalk® communication protocol as individual phase measurements and sum or average readings
• Measurements are transmitted as Standard Network Variable Types (SNVTs) through a LonWorks gateway
• LonWorks is a networking platform developed by Echelon Corporation that supports interconnection of various devices through a twisted pair connection
• The communication protocol (LonTalk) is an accepted standard for control networking (ANSI/CEA-709.1-B)
• The WattNode for LonWorks meter is available in standard and revenue-grade accuracy and can be used with any low voltage (0.333 Vac) output CT
• Revenue-grade accuracy requires the use of current transformers with class 0.6 or better accuracy
• The ACTL series of current transformers are available with class 0.6 or class 0.3 accuracy; these CTs are ideal for revenue grade applications such as tenant billing, Solar Renewable Energy Credit (SREC), and utility revenue-grade requirements
• Calibration certificates are available for the WattNode Revenue meters and the ACTL revenue-grade current transformers
• The WattNode meter’s compact size permits installation inside most electrical service panels, junction boxes, and OEM equipment
• The WattNode LonWorks meter is line-powered and does not require a separate power source
• The complete line of WattNode energy meters measure 1, 2, or 3 phases in 2, 3, or 4 wire configurations, 120 to 600 Vac, 50 to 60 Hz
• Socomec offers a complete line of low-voltage, split-core and solid-core current transformers with ratings from 5 to 6000 amps
