APS-7306L DC Programmable Power Supply

• Sudden switch from CV to CC mode
• Output voltage drops
• Protection indicator lights up

In such cases, disconnect the load and verify settings before continuing.

• CV (Constant Voltage): The voltage stays fixed, current varies with load.
• CC (Constant Current): The current stays fixed, voltage changes to maintain that current.

The power supply automatically switches between these modes as load conditions change.

• Linear power supply: Low noise, stable output, ideal for sensitive analog electronics.
• Switching power supply: Smaller, lighter, more efficient, but produces higher noise.

The APS-7306 operates in two main modes:

• CV (Constant Voltage) – maintains a stable output voltage while current varies with the load.
• CC (Constant Current) – maintains a stable output current while voltage adjusts automatically.

These modes ensure reliable protection for sensitive electronic devices.

Yes. The APS-7306 includes multiple memory channels that allow you to store and recall preset voltage and current settings quickly — perfect for repetitive tests or production environments.

The APS-7306 includes:

• Over-voltage protection (OVP)
• Over-current protection (OCP)
• Short-circuit protection
• Thermal overload protection

These features safeguard both the power supply and your connected devices.

If your APS-7306L(LS) programmable power supply is not working through the LAN (Ethernet) connection, there are a few common reasons:

1. USB connection priority: The APS-7306L(LS) power supply gives priority to the USB interface. If the USB cable is connected, the LAN (Web, LXI) interface will not function. To use LAN control, disconnect the USB cable from the power supply.
2. Incorrect IP address settings: If the IP address in the power supply settings is incorrect, the LAN connection will not work. To configure the correct IP:
   • Connect the APS-7306L(LS) via USB.
   • Use software such as Aktakom Power Manager Max.
   • Open the Connection Settings window by pressing the Connect button.
   • Set the correct IP address and click Write LAN Options to Power Supply.
   • If necessary, you can also reset the LAN settings to default values.

This ensures that your APS-7306L(LS) power supply works correctly over LAN without conflicts.

The APS-7306(L/LS) programmable DC power supply supports two main operating modes:

1. Constant Voltage (CV) Mode – Voltage Stabilization
   • This is the most commonly used operating mode.
   • When you press the Output button, the display shows the set voltage, while the current is measured in real time.
   • If the current draw increases and reaches the set maximum limit, the power supply automatically switches to Constant Current mode to protect the load.
2. Constant Current (CC) Mode – Current Stabilization
   • In this mode, the power supply lowers the output voltage so that the current does not exceed the set maximum value.
   • It is important to set the maximum current value before operation.
   • If the maximum current is set to zero, no voltage will appear at the output when you press Output.
   • We recommend setting the current to the minimum required value to protect sensitive electronic devices from accidental short circuits or overloads.

By automatically switching between CV mode and CC mode, the APS-7306(L/LS) ensures stable operation and safe protection for your test circuits and electronic equipment.

To connect the APS-7306LS programmable DC power supply to its control software, follow these steps:

1. Connect the USB cable from the APS-7306LS to your computer.
2. Launch the power supply control software (for example, Aktakom Power Manager).
3. The program will automatically detect and connect to the APS-7306LS.

⚠️ Important note: While the APS-7306LS is connected via USB and controlled by software, manual front-panel control will be disabled. To return to manual operation, disconnect the USB connection and restart the power supply by turning it off and back on.

This ensures smooth switching between software control and manual control of the APS-7306LS.

The APS-7306(L/LS) programmable DC power supply allows you to store up to 3 sets of voltage and current values in its memory for quick recall. This feature is useful for laboratory work, testing, or when frequently using the same output settings.

To memorize voltage and current values:

1. Set the desired output (for example, 5V / 1A).
2. Press MEM and then M1 to store this setting.
3. Adjust to another set of values (for example, 12V / 2A).
4. Press MEM and then M2 to store the second setting.
5. Set a third output value (for example, 24V / 3.5A).
6. Press MEM and then M3 to save the third configuration.

Once stored, you can recall these saved values instantly, without re-entering them each time. This makes the APS-7306(L/LS) more efficient and reliable for repeated power supply tasks.

The control software for the APS-7306LS programmable DC power supply is designed with several functional blocks that make it easy to monitor and adjust voltage and current settings:

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.

AKTAKOM programmable power supplies are equipped with different types of protection to ensure safe operation of the device and connected equipment. The protection method depends on the model series:

1. Current Stabilization (CC Mode) – Used in Entry-Level Power Supplies

• In low-end models, current protection is handled by the Constant Current (CC) stabilization mode.
• If the load resistance decreases (or a short circuit occurs), the power supply automatically reduces the output voltage to the minimum level.
• The supply remains in this safe state until a load resistance is detected again.

• Once resistance appears, the voltage and current increase proportionally up to the set values.

2. Over Current Protection (OCP Mode) – Available in High-End Power Supplies

• Advanced AKTAKOM power supplies include Over Current Protection (OCP) in addition to current stabilization.
• OCP mode is independent of CC mode and allows you to set a specific current limit at which the power supply output will shut off completely.
• After OCP is triggered, the output terminals remain off until reset manually from the device control panel, regardless of load changes.
• This provides an additional safety layer, especially for sensitive electronic circuits.

3. Multi-Channel Power Supplies

• Multi-channel AKTAKOM models support OCP per channel as well as total output current OCP for the entire device.

Key Notes:

• Devices without OCP rely only on current stabilization (CC mode) for protection.
• Devices with OCP provide a trigger-based protection that fully shuts off the output.
• In both cases, when protection is activated, the load is not galvanically isolated from the power supply output terminals.

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.

The program automatically reads the serial numbers of all devices found. To detect the device open Settings window, go to Connection and Presets tab, select the right device type you need in the list of models and click “Detect”:

In the list of detected devices you will see all names and serial numbers of the devices found.
