Basic Operations
Connecting to AC source
1. Place the Power Supply on horizontal, stable surface avoiding direct sunshine.
2. Place the Power Supply at least 10 cm away from the walls for good air circulation.
3. Check the correspondence of the position of input voltage value switch to the specifications of AC circuit,
to which you connect the Power Supply.
In case there is no such correspondence the Power Supply may be damaged.
Do not use the DC or another AC which does not correspond 110-120V or 200 – 240V, 50-60Hz.
4. Put the AC cord into the socket on the backside of the Power Supply.
“ON”
Check the correspondence of the position of input voltage value switch to the specifications of the network.
1. Plug the AC cord into the outlet.
2. Connect the load to the output terminals with the help of DC cable.
3. Put the voltage and current regulators into the extreme left position.
4. Put the power switch into the position “ON”.
