DPR-350 User Manual Ver_01 Firmware V-1.0
DPR-350 is a state of the art network analyzer and
protection relay in 96x96 standard panel dimensions.
Thanks to its low depth, it provides space economy.
The DPR-350 features dual current measurement
circuits. It is both a precise analyzer and a protection
relay. Protection curves can be selected among IEC,
ANSI, UK and US standards. Multiple protection curves
can be activated simultaneously.
Multiple measurements can be viewed on the 128x64
pixel graphic display of the device.
The unit records every electrical parameter to its built-in
1MB (16MB optional) memory at the desired sampling
rate. The records can be read via Modbus.
Through its RS-485 port, the unit can connect to various
Scada systems and can be remotely monitored.
Parameter configuration is done via USB port.
The unit offers 4 digital inputs, 2 relay outputs, and 3
analog outputs as standard. Analog outputs can be used
to receive desired measurements in the form of 4-20mA
signals, or to drive a visual fault mechanism.
