Product Description

The DTS 305 digital 3 phase power meter and power transducer provides you with unprecedented functionality, flexibility and performance in electrical measurement and control. This powerful meter is an extremely compact, easy to configure, simple to install IED (Intelligent Electronic Device). With the DTS 305, you only pay for the power meter usage hardware, software and functionality which you require, making this one of the most cost-effective products of its kind available on the market today.

This meter provides the full spectrum of instantaneous and integrated electrical power measurements as well as flexible I/O options. These I/O options offer up to 6 onboard outputs, each of which may be independently ordered as either digital or analog as well as 4 digital I/O relay outputs or status inputs.

The DTS 305 is a 3 phase power monitoring device which may be used for 3 or 4 wire systems. This makes the DTS 305 ideal for a wide range of applications from monitoring of power networks, load management to check metering. All of the DTS 305’s measurements are available via its on-board Ethernet port. These may be viewed using the DTS Display local indication module or the DTS Config software system. The DTS 305 may be operated in stand-alone mode or integrated into a higher order energy management or SCADA system using its second RS-485 port running either Modbus or DNP 3.00 communication protocols.
