Power Solution for DTU Application

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

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.
