Power supply operation instructions

1. Output Voltage Adjustment: Press the key [VSET] and then the value of voltage setting will be displayed on the voltage display; and the place setted flickers. Repress and the selected place of the setting values will be changed. And turn the knob and the setting value of the output voltage will be adjusted when the setted place flickers. Stop turning for a few seconds, then the setted place stops flickering and the power will return to the initial status.
2. Output Current Adjustment: Press the key [ISET] and then the value of voltage setting will be displayed on the voltage display; and the place setted flickers. Repress and the selected place of the setting values will be changed.
   And turn the knob and the setting value of the output voltage will be adjusted when the setted place flickers. Stop turning for a few seconds, then the setted place stops flickering and the power will return to the initial status.
3. Over current protection: Press the key [RECALL] and the storage direction will flicker. At this time, press [OUTPUT] and it will stop flickering, when the power is in the mode of over current protection; that is, the over current protection starts when the current is up to the setted value; Switch off the output voltage and the over current protection light [OCP] is on. Eliminating the mode of the over current protection: press the key [RECALL] and the storage direction will flicker. At this time, press [OUTPUT] and it will stop flickering, when the power supplies will exit from the over current protection mode.
4. Storage Selection: Press the key [STORE] and the storage direction light will flicker, which indicates the current storage data. Then press the key [ i ] and the next parameters of voltage and current can be selected; press [ t ] and the previous parameters can be selected. In any storage direction, the relevant storage units can be stored when the parameters of voltage and current are setted.
5. Switching on or off the output: Press the key [OUTPUT] and the output voltage will be switched on or off.

What current protection do AKTAKOM power supplies use?

AKTAKOM power supplies use 2 types of protection. In low end power supplies the current protection is provided mostly by "current stabilization" (CC) mode. When the load resistance decreases (or short circuit) the power supply reduces the output terminals voltage to the minimum level and remains in this condition until the load resistance appears on the terminals. When resistance appears, voltage (and current) will increase proportionally to the set value. High end power supplies have also over current protection mode (or OCP mode) in addition to the current stabilization mode. OCP mode is activated regardless of current stabilization mode and allows you to set any current limit value at which the power supply will turn off the output terminals voltage. After the protection is activated the power supply terminals will stay off until some certain buttons on the device control panel are pressed, regardless of the load state. Multi-channel power supplies use OCP options both for separate channels and for the total output current of the power supply. Thus we may assume that devices without OCP mode use current stabilization mode for the current protection. In devices equipped with OCP mode the current protection works in the trigger mode. However it should be noted that in both cases, when the protection is activated, the output terminals (and the load) are not galvanically isolated from the power supply. Up

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. Up

How to change voltage and current values?
To change voltage and current values use "V SET", "I SET" buttons and adjusting knob as shown below: Up
