AKTAKOM ATH-3243 is a high-precision DC regulated power supply which is widely used in debugging process, repair and laboratory research. Besides other applications it’s a perfect power supply for science investigation, college, factory, electronic appliance maintenance and etc.

ATH-3243 outputs smoothly adjustable stabilized DC voltage and stabilized current. The model has three ways output: two ways are adjustable and one way is fixed.

The two adjustable outputs can also be selected for constant voltage or constant current, designed in high stability and performance circuit. In constant voltage state the output voltage can be arbitrarily adjusted from 0V on in the nominal range; and in the state of constant current the output current can be adjustable from 0A on in the nominal range. The two outputs can be connected in parallel or in series.

The one fixed way outputs 5 V voltage. Due to the single chip integrated regulator this output has good stability and ripple factor and it has reliable overload protection to protect ATH-3243 against being damaged whenever overload or short circuit.

The unit structure is rather compact, this allows ATH-3243 to occupy a minimal space and organize a high performance work area. Other features of this power supply include high performance, short circuit protection availability, modern design etc.

ATH-3243 has a digital indication, all information is displayed on 4 3-digit LED displays.


  • 4 3-digit LCDs
  • Separate current and voltage indication
  • Indicators of current (CC) and voltage (CV) stabilization
  • Short circuit protection
  • Stabilization mode (current, voltage)
  • Tracking mode for adjustable channels

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.
