APS-7306 Linear, adjustable DC Power Supply 30V 5A, precision control, mode - CC, CV, memory, with Free AKTAKOM Original Software Control via PC, preset, and even one of the kind Voice Guide

• 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.

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.

Yes. The AKTAKOM APS-7306 programmable power supply allows you to store up to 3 sets of voltage and current values in its internal memory for quick recall.

The procedure for saving voltage and current settings is simple:

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

This feature makes it easy to recall frequently used voltage and current settings without re-entering values manually, improving workflow and efficiency in laboratory or testing environments.

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.

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.

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.

For safety reasons, the AKTAKOM APS-7306 programmable DC power supply does not allow the remote control mode to be disabled directly from the software. This prevents accidental switching that could endanger the connected electronic equipment.

To return to local (manual) control mode:

1. Turn off the APS-7306 power supply.
2. Turn it back on without connecting it to the computer via USB.

This ensures the safe operation of the power supply and connected devices by requiring a controlled restart before manual control can be restored.

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.
