According to the way of the connection, the product can offer power to instrument and charge
MP3450I at the same time. When the AC power is shut down, that’s to say, the output voltage of
AC power adapter is 20% lower than normal , the MP3450I will be exchange the battery power
to the connected instrument. So it’s same as the UPS function( uninterrupted power system ).
Low Capacity Alarming Function:
When the battery capacity is below 3%—5%, it will alarm for 3~5min, which depends on the
value of the loading current.
Connection Step
1. Select the suitable output voltage of MP3450I by Dip Switch; according to the DC IN
Voltage of connected instrument; and the adjusting methods of Dip Switch are follow as
above.
2. Plug the output of the AC Power Adapter into the DC IN Charge input port of MP3450I.
3. Choose a suitable DC output tip to fit the DC IN Jack’s dimension of connected
instrument.
4. Connect the suitable output tip with the power output cord, and another terminal of power
output cord to connect with the DC output port of MP3450I by the Din connector.
5. Turn on the MP3450I and make sure that the power ON/OFF LED lights.
6. Measure the DC output voltage of output adapter tip by multi-meter and make sure that it
goes with the voltage you selected.
7. Plug the output adapter tip of the power output cord into the DC in Jack of the connected
instrument after checking.
8. Turn on the instrument and make sure whether it can work normally.
