Certified with the Sunspec Alliance, it implements Modbus optimally and easily integrates with Building Automation Systems and Energy Monitoring Software.

The DTS 307 is designed to be DIN rail mounted. We also offer an optional right angle bracket.

When choosing CTs to work with the DTS-307, you want to look for AC Amp Input, AC Voltage Output current sensors. They will have this symbol:

AC Amp In, AC Voltage Out

Be aware that the DTS-307 Modbus meter is a high accuracy device. For best performance buy high accuracy CTs such as the LNxF Series (0.2%), the 4LSF (0.5%) or the SCT-125H (0.5%).  Accuracy is only as good as the weakest link.
