APS-7306LS DC Programmable Power Supply

We have added a number of new features to AKTAKOM Power Manager 21 Pro, trying to keep it simple and easy to use.

Template management

AKTAKOM laboratory power supplies can supply current with arbitrary parameters precisely set by the user, but in practice a number of parameters with fixed values are most often used - 1.5 Volts, 3.3, 9, 12 ... In APM21 Pro, you can make a list of your "favorite" values in advance voltage and current and then set them to the device with one click.

Command list management

Another important property of our power supplies is the ability to dynamically change the current output parameters. APM21 Pro can do this automatically. Set a list of commands to the device in advance, specifying the necessary parameters and time, save the list to a file and run it for automatic execution when you need it.

Customizable user interface

In addition to additional ways to control the device, the main window of the program also has a graph displaying the history of measurements received from the device. All this may seem redundant and cluttering for someone who plans to use the source for simple standard tasks. In this case, you can customize the user interface in a way that is convenient for you: hide and collapse all the blocks you don’t need with special buttons and leave only the ones you need.

Saving data

If your lab's power supply is used for research, you may need to review instrument operation later. Therefore, we saved the history of events (displayed in the Protocol window) and measurement data (displayed on the graph in the main window) to a file.

Sync input is a 2.5 mm audio jack stereo. The counterpart is a 2.5 mm audio jack plug. The scheme of this plug for synchronization signaling, see pic. 1.

Note! In APS-7306LS power supply the signal of pin 2 input of the sync connector is also used to reset network settings to default. APS-3xxxLS power supplies do not use this signal.

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.

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.

The program has several blocks: the top block is setting up the program window and information buttons. You can close the clock, remove signatures, hide advertising. HELP can be called if necessary.

The Initialization Box shows the connected device - APS-7306LS.

The Measurement Box is a main window and shows the voltage and current values produced by Aktakom APS-7306LS. This box shows the operating mode - voltage stabilization CV or current stabilization CC.

The SetUp Box has buttons for entering values - manual numbers, buttons - up - down, slider - right - left, and quick setting of pre-specified values.

To enter pre-set values, you need to use the gear buttons. A window will open containing a list of preset values. This list can be edited. You need to use the buttons - change the value of the current line, add a new value to the list or remove a value from the list.

At the bottom of the program window we have a large button - exit.

Pressing it connects the load to the power supply output.

First connect the USB cable to the computer and when the program starts, the program finds and connects itself to the the APS-7306LS. It is important to remember that the APS-7306LS will remain without manual control until the APS-7306LS is turned off and turned on again without connecting to a computer via USB.

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

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.

APM Max Pro has additional functions comparing to APM Max:

• 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;
• Customizable user interface: you can hide and collapse all the blocks of the main window you don't need and leave only the ones you need. Also you can choose to hide or show the manual control blocks, control presets, synchronization, news feeds. User interface settings can be saved and restored.
