APS-3205 DC Power Supply 315W 30V / 5A 2CH+1Aux

Absolute error of my measurement

"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.

The AKTAKOM APS-3205 is a highly reliable regulated DC power supply providing high precision and high stability. This model can be widely used in laboratories, electronics production lines, communications equipment repair. It’s a must have device for scientific research, production, teaching and other applications.

As the most of other multichannel power supplies AKTAKOM APS-3205 uses parallel and series connection of controlled channels. This feature allows you to use multichannel model as a single channel device. At the same time the maximum voltage value can be increased up to 60 V (in series connection of channels). In parallel connection the output current value can be increased twice.

To ease the operation process there is tracking control mode used both with parallel or series connection of channels.

Frequently Asked Questions

  • May I use AKTAKOM power supplies to charge accumulators?
  • Can APS-3205 (APS-3203) power supply be used to supply the amplifiers on operational amplifiers?

  • 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.


    Can APS-3205 (APS-3203) power supply be used to supply the amplifiers on operational amplifiers?

    These amplifiers require bipolar power supply +15 V.

    In APS-3205 (APS-3203) such bipolar power supply is provided by the connection of output sockets of two different channels in order to get a general output (pic.1). Such a connection is very similar to the connection of two batteries to get a general power output (pic.2).

    It’s recommended to choose tracking – control mode in the power unit. In that case supply voltage change will be made simultaneously in two channels of the power supply and voltage in two amplifier arms will be the same respectively.
