DATAKOM DPR-350 Network Analyzer with Multifunctional Protection Relay, 19-150VDC power supply

* All prices are retail and VAT exclusive

DPR-350 is a state of the art network analyzer and directional protection relay in 96x96mm standard panel dimensions.
The large graphic screen allows simultaneous display of multiple measurements.
The DPR-350 features dual current measurement circuits. It is both a precise analyzer and a 25Amp protection relay.
Protection curves are selected between various IEC, ANSI, UK and US types. Multiple curves may be enabled simultaneously.
Through RS-485 comport, the unit is easily connected to Scada and automation systems. Parameter adjustment is done through USB port.
The unit records all electrical parameters with adjustable period in its 1MB record memory (optional 16MB). Records are read through Modbus.
The unit offers 4 digital inputs, 3 analog outputs and 2 relay outputs. Analog outputs can give any measured parameter in 4-20mA format.
