13) Do not rely at your work only on the measuring devices of the AC power supply!

14) Use at your work only the tools determined for this purpose!

15) All conductors connected to the device's outlets have to be equipped with a suitable

isolation!

16) In a case the device shows some failure, keep it out of operations and give it to repair

in a specialised service.

17) Do not shorten the outgoing connectors.

18) Do not disassemble the device.

V. Work with the AC Power Supply

Plug the power flex cable to the socket outlet 230 V/ 50 Hz. Put the AC Power Supply in

operation by switching the switch of mains (5). After switching-on is running the test and setup

of the alternating power supply, which is signalised by light up of 888 on all displays (1;8).

During this period is the output of the device blocked (7).

Model AC250K1D (AC250K2D): Approximately after two seconds are the displays switched to

the operational mode and show 0. At the same time is activated the control keyboard (4) and a

short acoustic signal sounds. Output voltage is setup on OV and the output is not connected.

Model AC250K2D-S (AC250K2D-S): Approximately after two seconds are the displays

switched over to the operational mode, where are displayed first the data showing if the

stabilization is switched-on/switched-off (StA ON/OFF) and then is displayed O, eventually the

previous set value – see the text below. At the same time is activated the control keyboard (4)

and a short acoustic signal sounds. Output voltage is setup on OV, eventually on the previous

set value and the output is connected according to its own setup.

The voltage of the AC Power Supply is possible to set in the range between 0V÷255V

with using the keyboard, the minimum possible step is 1 V.

V.I. Voltage output setup

With help of the numeric keys set the requested voltage value. When you start to set the

voltage value, the indicator SET (3) starts to blink. The set value is displayed on the display

SET (1). The preset value confirm by pressing the key ENTER (14). Then the real voltage

value is displayed on the display REAL (8). In a case you set a wrong value, you may cancel it

by pressing the key C (15). If you set the voltage value higher than 255 V, there will be

displayed on the display SET (1) the sign Err. It is necessary to clear the set value by pressing

the key C (15) and then to set a new voltage value. The set value you will bring to the output

by pressing the key OUT (13). Pushing of any key is signalised by a short beep.

V.II. Accurate setting of the voltage output

Due to the fact, that the output voltage is made by transformation of the mains, a different

voltage than the preset could appear thanks to the oscillation of the mains. For accurate

setting you can use the keys UP (10) and DOWN (11) and also the display REAL (8). Pressing

of the key UP (10) increases the voltage, key DOWN (11) decreases the voltage. Longer

pressing of the key caused increasing or decreasing the value by 6V/1s.
