SOFTWARE
Software overview
The standard package of the device includes AKTAKOM Power Manager ( APM
) and AKTAKOM Power Manager 21 Light (APM21 Light) software. 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 device 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! Be careful! Disconnection of the USB or LAN cable or the controlling program will return the voltage and current values which were set manually using «LOAD» button and the rotary switches on the front panel (Fig 1: 11, 12, 13). Always before entering the remote control mode it’s recommended to switch off «LOAD» button. If you have any questions concerning the use of interfaces or the software check the detailed description and the section with frequently asked questions at www.tmatlantic.com and www.aktakom.com.
GENERAL INFORMATION
Technical service
NOTE! The following instructions are for qualified personnel only. To
avoid electric shock, do not perform any other services other than those
contained in the User manual.
Fuse replacement
When the fuse in the AC circuit gets out of order none of the LEDs are lit,
and the power supply will not operate. Try to identify and eliminate the
reason for the fuse blow, and only after that replace it with a fuse of the
same type and with the same parameters. Fuse installation is made on the
device rear panel.
Cleaning
Device cleaning should be done with a slightly damp flannel cloth soaked in
soap solution. Before cleaning, make sure that the power cable of the device
is taken off. If the device housing still has firm spots remained remove them
with a cloth wiped with alcohol. After cleaning let the device dry completely.
Avoid using solvents, such as benzene, etc.
Storage and transportation
Storage conditions: environment temperature: –20…+60 °C; relative air
humidity is not more than 80 % with 25 °C. Transportation conditions:
environment temperature: –20…+60 °C.

OPTIONAL SOFTWARE
Optional software:
- AKTAKOM Power Manager 21 Professional (APM21 Pro)
- APS-3xxxLx_SDK Software Development Kit.
- APS-3xxxLx_SDK_Base Software Development Kit.
There are several advantages of APM 21 Pro vs APM 21 Light.
-
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 www.tmatlantic.com (displayed on the graph in the main window) to a file.
The APS-3xxxLx SDK is designed to help users in creating their own applications for the supported hardware. This SDK contains the device driver for controllable power supplies from the series of AKTAKOM Power Supplies APS- 31xxL, APS-33xxL, APS-36xxL.
The driver contains all necessary functions for the device operation and represents dynamic-link library (DLL) Windows followed with the library header file in the C programming language, with Lab Windows 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.
The driver library function can be also called from any programming environment with the ordinary for DLL method. As an example of such driver use there are projects for Borland C++ Builder 6, NI LabWindows/CVI and MS Visual C++ used.
The main advantage of the full SDK package is fast development of applications basing on the programming examples for different programming environments allowing you to use the proposed typical structure of the application.www.tmatlantic.com
