Product Description

The DTS 307-xx-x-xxC Series of multi-circuit monitors has been designed to provide a single metering solution for 9, 12, 18 or 24 branch circuits (3, 4, 6 or 8 Three phase circuits).

The series is based on the ultra-compact DTS 307 3 channel 208V-480V sub-meter.

It is offered in 2 formats:

  • Pre-wired with 1.5ft voltage pigtails on a DIN rail to be mounted into a 3rd party enclosure
  • Wall-mounting, non-metallic weatherproof enclosure adder with voltage terminals or fuses.

It is available with serial or ethernet communications with Modbus or BACnet protocols

The DTS 307 can be configured to operate as a Bi-directional NET meter. The DTS 307 is SunSpec Alliance certified and easily integrates with Building Automation Systems and Energy Monitoring Software. All the DTS Series is designed and manufactured in the USA and complies with the Buy American Provisions of ARRA Section 1605.
