Operation instructions

  1. Ensure that the power plug of this unit is connected to a 110V AC power outlet before using, switch the power ON, and adjust the (8)~(9) knobs to set the voltage to the desired value, and then plug your output cords into the output terminals (10)~(11), now the current meter (1) will show the current value.
  2. The limiting value of the output current is 3A or 5A depending upon the model, you must disconnect the power immediately when the over load indicator (6) is on.
  3. Setting of current limiting.
    - Use a short-circuit wire to short the current terminals (+) to (-).
    - Adjust the current knob untill the CC indicator is on.
    - Adjust the current knob to the desired value (4) & (5).
    - Take off the short circuit wire.
(1) Current meter: displays output current value
(2) Voltage meter: displays output voltage value
(3) Power switch: control the power
(4) Output current fine knob
(5) Output current course knob
(6) Constant current mode indicator
(7) Constant voltage mode indicator
(8) Output voltage coarse knob
(9) Output voltage fine knob
(10) Power output “-” terminal
(11) Output “+” terminal
(12) Ground (Earth terminal)

Frequently Asked Questions

  • May I use AKTAKOM power supplies to charge accumulators?

  • May I use AKTAKOM power supplies to charge accumulators?

    AKTAKOM power supplies can’t be used for accumulator charging since it may cause the accumulator breakage (recharge, electrolyte boiling, extra pressure of the internal gas which will lead to the accumulator explosion). Accumulators should be charged with the current source which controls the accumulator voltage and regulates the charging current accordingly. When the required accumulator voltage is achieved such type of source simply stops the charging process, its name is a charging device.
