Using the Power Supply in Constant Current Mode

If you want to use the power supply in constant current mode: you set up the desired output current between 0A and 3A/5A. You also set up the desired voltage limit.

Using the Power Supply in Constant Voltage Mode

If you want to use the power supply in constant voltage mode, you set up the desired output voltage between 0V and 30V. You also set up the desired current limit.

If the output current exceeds the limit, the power supply automatically goes into constant current mode.

Switching the Power Supply On or Off

Connect the included power cord to the back of the device (see the pic. below) and plug the other end into a suitable, earthed power socket. Always connect the device to an earthed power socket!
Press the Power button on the front panel to switch the power supply on. At this moment, there is no output voltage or current on the output terminals.

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

When I press “Remote” there is nothing happening to AKTAKOM APS-7306 power supply control. What is the reason?
In order to ensure the safe operation of AKTAKOM APS-7306 power supply and the connected equipment the command to turn off the remote mode in the program does not work. To switch to local control turn the power off and then on again. Up

Does the current parameters on AKTAKOM APS-7306 power supply display coincide with the readings of the program?
Current parameters on AKTAKOM APS-7306 power supply display may not coincide with the program readings if there is no load connected to the device. Up

How many operating modes does the APS-7306(LS) DC Programmable Power Supply have?
The APS-7306(L/LS) power supply has two operating modes - voltage stabilization (CV) and current stabilization (CC). Voltage stabilization mode is the most commonly used operating mode. When we turn on the “output” button, in the voltage stabilization mode we see the set voltage value, and the current value will be equal to the measured one. If the current value constantly increases, then when the set maximum value is reached, power supply will automatically switch to current stabilization mode and reduce the output voltage. Current stabilization mode is a mode in which the output voltage will be reduced so that the current does not exceed the set value. Therefore, you should always set the required maximum current value. If the required maximum current value is not set, then there will be no voltage at the output after pressing the “Output” button. Simply, when the current is set to zero, there should be zero voltage. We recommend that you always set the current to the minimum required. This will protect your electronic equipment from accidental short circuits during operation. Up

Can I memorize the voltage and current values for the APS-7306(L/LS) DC Programmable Power Supply?
In APS-7306(L/LS) DC Programmable Power Supply, for ease of use, when setting typical values, you can memorize up to 3 voltage and current values. It’s easy to memorize the values - we enter the voltage and current values for example, 5 volts and 1 ampere and press the MEM and M1 button. Next, set a different value for voltage and current 12 volts and 2 amperes and press the MEM and M2 button and for the 3rd time - 24 volts and 3.5 amperes and press the MEM and M3 button. Up

Can I store voltage and current values in the device memory?
APS-7306 DC power supply has the ability to store 3 voltage and current values. The procedure for saving values is simple - enter, as described earlier, the voltage and current value, for example, 5 volts and 1 ampere and press the MEM and M1 button. Next, set the voltage and current value, for example, 12 volts and 2 amperes and press the MEM and M2 button. And for the 3rd time - set the voltage and current value, for example, 24 volts and 3.5 amperes and press the MEM and M3 button. See Video Tutorial for real life application Up

I was told there is a video tutorial for this device where can I see it?
To watch a video tutorial please go to "Video" section. Up

Can I Turn-Off News and Events feed on my Control Panel?
To turn off the News and Events feed click on Aktakom Logo as shown on the picture. To turn it back on click on the Logo again. 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

What languages does the voice guide support?
Voice guidance works in all languages installed in the operating system on your PC. Up

What are the advantages of APM Express Pro vs APM Express?
APM Express Pro has additional functions comparing to APM Express: Display of current power and integral consumption; Automatic control of the power supply output voltage and current in accordance with the pre-set sequence of commands; Event log (in text format); Measurement history graph. Up
