    What current protection do AKTAKOM power supplies use?

    AKTAKOM power supplies use 2 types of protection.

    In low end power supplies the current protection is provided mostly by "current stabilization" (CC) mode. When the load resistance decreases (or short circuit) the power supply reduces the output terminals voltage to the minimum level and remains in this condition until the load resistance appears on the terminals. When resistance appears, voltage (and current) will increase proportionally to the set value.

    High end power supplies have also over current protection mode (or OCP mode) in addition to the current stabilization mode. OCP mode is activated regardless of current stabilization mode and allows you to set any current limit value at which the power supply will turn off the output terminals voltage. After the protection is activated the power supply terminals will stay off until some certain buttons on the device control panel are pressed, regardless of the load state.

    Multi-channel power supplies use OCP options both for separate channels and for the total output current of the power supply.

    Thus we may assume that devices without OCP mode use current stabilization mode for the current protection. In devices equipped with OCP mode the current protection works in the trigger mode.

    However it should be noted that in both cases, when the protection is activated, the output terminals (and the load) are not galvanically isolated from the power supply.

    What is the assignment of Aktakom Power Manager?

    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.

    1. The software has no physical media (CD) and can be downloaded at www.tmatlantic.com after registering the equipment with a serial number. Therefore follow Product registration link on www.tmatlantic.com
    2. PC installation of AKTAKOM Power Manager Software is instructed on www.tmatlantic.com and www.aktakom.com
    3. 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 install the device driver for the operation via USB?

    Device USB driver can be installed in several stages.

    At the first stage files necessary for the driver installation should be copied to the PC hard disk. It happens during APM program installation. At this moment the device shouldn’t be connected to the PC USB port.

    When the installation is completed the installer will suggest connecting the device via USB, afterwards it will start installing the copied driver files into the operating system.

    If you missed this stage or for some reason driver auto installation failed you may install the driver manually in an ordinary way for Windows any time in the future. In this case connect the device to your PC, wait for Add New Hardware Wizard and specify the path to the driver files on the installation disk or in the working folder of the installed program, for example: «C:\Program Files (x86)\AKTAKOM\AKTAKOM Power Manager\Driver».
