DTU Introduction
MORNSUN DTU (Data Transfer unit) transmits the
data of remote devices to the control center
wirelessly, which is widely used in electric
power industry, environmental protection,
physical distribution, hydrology, meteorological
industry, etc.
Typical Application of DTU
3
The figure is DTU application in power
distribution system. DTU collects the three-phase
current signal, voltage signal and switching
signal, and then operates according to the
analyzed data.1. Uninterruptible power supply
(double power supplies). Switching power supply
and accumulator can automatically switch to each
other. 2. DC-DC converters accept voltage change
caused by the charge and discharge of the
accumulator.3. DC-DC converters support 24V/48V
input of accumulator.4. High isolation voltage
prevents the coupled interferences from AC
end.5. If the main power supply and the
accumulator are both powers down, the protection
time is longer than 500ms.
