Large digital display with LED meter displays Volts & Amps. Push button switch allows connection & removal of load. Multiturn Voltage control for precise settings. Front panel output Banana Jacks & Terminal strip for remote Voltmeter Sensing at the load.
There is a four-wire (4-wire) connection scheme used. This connection method provides accurate voltage supply preset in the load. This leads to the compensation of the wire resistance connecting the power supply and the load that is especially important in the industrial application of the power supply.
AKTAKOM APS-3320L programmable DC power supply (analog of QJ3020E) differs from other similar power supplies by wide capabilities of local and remote control through AKTAKOM Power Manager software.
APS-3320L remote controlled power supply is capable of operating in several modes:
Manual control mode. Including the use of 4 memory cells to store preset voltage and current.
Remote control mode to operate AKTAKOM APS-3320L DC power supply by computer via USB interface through AKTAKOM Power Manager Software. Moreover the USB interface has full galvanic isolation between the power supply and the computer.
Remote control mode to operate AKTAKOM APS-3320L DC power supply by computer using an USB cable or LAN cable (ethernet).
Remote control mode to operate AKTAKOM APS-3320L DC power supply throught the remote access to the computer USB-connected to APS-3320L. AKTAKOM Power Manager Software provides the operation in «server-client» mode even for power supplies without built-in LAN interface. Meanwhile the power supply is physically connected to computer-server via USB interface and the data is available for reading from any computer of the network.
AKTAKOM Power Manager Software (APM) provides a wide range of control capabilities of output voltage and stabilization current both in manual and functional modes. Functional control is a very powerful tool of APM software which allows you not only to control your DC power supply automatically by computer but also to program its off-line operation mode by prespecified algorithm. Functional control mode in APM software allows automatically controlling the output parameters (voltage and current) of the power supply according to the principle specified with the help of graphics and tabular editors. In a convenient graphics editor user may specify 10 standard forms of parameters (including sine, square, triangle, saw, flash, pulse, 2 types of exponents, 2 types of S-curves), as well as, almost any arbitrary form which can be described formulary. The program operation in equipment operation compatibility mode is also available.
The software system for AKTAKOM APS-3320L remote controlled DC power supply includes a software development kit (SDK) to help users in developing their own applications. This SDK contains the device driver with all necessary functions for the power supply operation and represents dynamic-link library (DLL) Windows followed with the library header file in the C programming language, with LabWindows function tree and the tool library for LabVIEW which fully repeats it. Additionally (in contrast to APS-3xxxLx_SDK_Base Software Development Kit) it contains the examples of programming in the following development environment: Borland C++ Builder, MS Visual C++, NI LabWindows/CVI and NI LabVIEW.

"Absolute measurement error" service allows you to estimate the measurement accuracy considering uncertainty (error) in the absolute value. It's important if you take measurements at the range edge when the error value contributes to the value displayed on the device screen.
To get the value range it'd be enough to enter the estimate of the value under measurement into Value input field and to see the range of possible values taking all of the standardized errors into consideration.
Note: a point is used as a separator of the integer and fractional part.

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 Power Manager (APM) Software offers wide opportunities for controlling the output voltage and stabilization current both in arbitrary (manual) and in functional modes. Functional control is a powerful APM software tool which allows you not only to automatically control the power supply via your computer but also to program it for the off-line mode operation in accordance with the predetermined algorithm. Functional control mode in APM software allows you to automatically control the output parameters (voltage or current) of the power supply according to the law set by the graphical and tabular editors. In the convenient graphical editor user may set 10 standard forms of parameter changes (including: sine, square, triangle, saw, flash, pulse, 2 types of exponent, 2 types of S-curves) as well as any arbitrary shape which can be described with a formula.
Please note! When you run AKTAKOM Power Manager Software for the first time it will require an access key. This key can be received (copied) at www.tmatlantic.com after the product registration. The key can be entered later, see Settings/Pass key menu.

How to connect to the power supply via web-interface?
There is no web-interface remote control feature for this power supply. To control the power supply remotely use the software provided in the standard accessory kit for the device. Up
Do AKTAKOM power supplies have short circuit protection?
Yes they have.
Almost all modern power supplies have two operation modes: voltage stabilization mode and current stabilization mode. In case of short circuit the power supply automatically switches from the output voltage stabilization mode to the output current stabilization mode, and the output voltage starts proportionally dropping. At the same time the current in the load connected to the power supply will be limited with the value set with the screwdriver slot used to adjust the output current value on the front panel of the power supply. For the best protection it is recommended to set a low current value. In case of short circuit the current in the connected load will be limited with the value set on 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.
How to see a device serial number in AKTAKOM Power Manager software?
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.
