DTS-310 Sub-Meter by Measurlogic

Product Description

The Measurlogic DTS-310 is a Class 0.2 revenue grade sub-meter for single or 3-phase systems. The DTS-370 offers DNP 3.0, Modbus, BACnet, SNMP or LonWorks connectivity.

It is compact, line-powered and has a versatile array of options for optimal customization, including a selection of serial versus ethernet output, and your choice of DNP 3.0, Modbus, BACNet, SNMP or LonWorks.

The DTS-310 DNP sub-meter can be configured with up to 3 pulse outputs, or it can be configured to take up to 2 input pulses and still have a pulse output!  See the data sheet for more information on configuration options.

If you are interested in options not listed on our site, please call us at 303-772-6100 and we will be happy to take custom orders.

The DTS 310 is designed to be DIN rail mounted. We also offer an optional right angle bracket – click here or see Accessories section below for details.

When choosing CTs to work with the DTS-310, 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-310 sub-meter is a high accuracy device. You may want to buy high accuracy CTs such as the SCT-075H (accuracy is only as good as the weakest link). Another popular option, albeit “standard” 1% accuracy, is to pair the DTS-310 with one of Magnelab’s Rogowski coils.  Note that you DO NOT have to buy a Rogowski coil with an integrator (Measurlogic supports this natively).
