DPR-400 User Manual Rev_01 Firmware V-1.0
DPR-400 is a state of the art, color screen,
directional network analyzer and protection relay in
144x144mm standard panel dimensions. Thanks to
its low depth, it saves space in the panel. The device
combines high precision, ease of use and versatility
with a reliable and cost-effective design.
The DPR-400 features dual current measurement
circuits, making it a class 0.5% accuracy analyzer,
and a protection relay capable of measuring 50xIn.
The DPR-400 offers various protection curves to
provide precise protection. Multiple protection curves
can be activated simultaneously.
The DPR-400 displays multiple measurements on its
4.3
” screen. The large display offers ease of use and
provides abundant information.
The device can connect to various Scada systems
easily via USB, isolated RS-485 and Ethernet ports
for remote monitoring.
Modbus and IEC60870-5-103 protocols are
supported through RS-485 port.
Modbus TCP/IP and IEC61850 protocols are
supported over the Ethernet port.
Parameter configuration is done using the buttons on
the front panel or with the free PC software. The
program connects via USB, RS-485 or optionally
over the Internet. Additionally, firmware updates are
performed through the USB port.
Two of the relay outputs of the device have
connection monitoring capability. These outputs
continually check the integrity of the load circuit, and
raise an alarm if the circuit opens.
DPR-400 stores up to 7 oscillographic records in
COMTRADE format in its 1MB internal memory.
The device meets the security, EMC, vibration, and
environmental standards for industrial products.
