Product Description

One of the most versatile and accurate meters on the market. The DTS 310 has a very compact DIN rail design, requires no external power source to operate, and comes with color coded, pluggable connectivity. This meter is certified to ANSI C12.20 Class 0.2 (Revenue Grade) providing the most accurate data acquisition available. It can function in either a single, split or three phase environment and is equipped with auto-topology detection. The DTS 310 works with all “safe” 333mV, 5A or flexible Rogowski current transformers (CTs) and comes with CT Reverse Algorithms for automatic correction of improper field mounted CTs.

For easy configuration in-the-field, communications can be set via DIP switches when utilizing the Modbus RTU or BACnet MS/TP protocols. Or for remote configurability, all the DTS Series of meters are offered with our DTS Config software platform; where you can conveniently choose from over 200 parameters. It also has a User-definable Modbus register area.

The DTS 310 is available with optional digital status/counter inputs or digital outputs, which can be used to import gas or water meters or to control any third party device; and is offered with optional on-board logging with our DTS Logging System. Also, if in the future, you decide to integrate renewable energy sources, the DTS 310 will conveniently operate as a Bi-directional NET meter. The DTS 310 is SunSpec Alliance certified and easily integrates with Building Automation Systems and Energy Monitoring Software. All our DTS Series of meters are designed and manufactured in the USA and comply with the Buy American Provisions of ARRA Section 1605.
