Instruction manual
Adjustable pulse power supply N3111 is designed for powering appliances
operating under DC voltage and maximum current of 1,000 mA and input power of
12 W-valid for plugging in power connector no. 1. Output parameters for USB
connector no.2 are 5 V; 2 A.
The power supply can be used for devices with the appropriate current and
input power values on their label up to a maximum value of 1,000 mA (12 W) –
valid for powering using the power connector or for powering/charging
smartphones or tables via the USB (no. 2). Both sockets are independent; you
can use only socket 1 or socket 2 or both together.
The output voltage of the pulse power supply is stabilised – the voltagevalue
is kept at the set level regardless of the load.

Connection procedure – socket no. 1
-
. Current and input power – check the appliance’s label to make sure it uses the appropriate current and input power in mA and W. The value must be equal or lower than 1,000 mA and 12 W; valid for plugging in the cable via connector 1.
-
Output voltage can be adjusted – use the turn switch to set the desired voltage based on the appliance. The turn switch is located on the bottom side of the power supply so that there is no risk of accidental switching of the voltage value during operation.
-
Output connector – choose a connector suitable for your appliance (you can test by plugging into the socket in the appliance first).
-
Choose the connector‘s correct polarity according to the label on your appliance. Then insert it into the socket at the end of the cable of the AC adapter. See the scheme below.
-
If the appliance is not being charged or it doesn‘t work, the most probably the voltage polarity of the charging source needs to be changed. Disconnect the charging connector immediately from the socket of the charging source, turn it about 180 degrees and insert it into the cable again.
-
If the appliance does not run or runs incorrectly, immediately disconnect the power supply from the appliance.
Connection procedure for socket no. 2 USB
- Socket no. 2 is a USB socket for powering/charging smartphones, tablets and other devices with the required voltage of 5 V.
- Output voltage is max. 5 V/2 A.
- Connect the USB cable–USB connector type A from your device (not included) into adapter socket no. 2.
- Connect the other end of the cable to your device (e.g. micro USB, USB-C, lighting).
- Plug the adapter into a power socket and your device will be powered /charged.
- After charging is complete, unplug the adapter from socket.
Do not dispose of electrical appliances as unsorted municipal waste; use sorted waste collection points. Contact local authorities for up-to-date information about collection points. If electrical appliances are deposited in waste landfills, hazardous substances may leak into the groundwater, enter the food chain and harm your health.
