Power supply to load four-wire connection method

The sampling terminals are used under the following conditions: if the load has a distance from the power supply, the sampling terminals may be used to compensate for the inherent when using voltage drop a longer power line.

Sampling terminals connection to compensate the voltage drop

Attention! Disconnect the installed S- and S+ shorting wires when using the sampling connections.

Frequently Asked Questions

How can I work in the current stabilization mode?

What instruction should I follow to work in the voltage stabilization mode?

Do AKTAKOM power supplies have short circuit protection?

May I use AKTAKOM power supplies to charge accumulators?

How can I work in the current stabilization mode?

If OUTPUT indicator is red than press LOAD button. In that case OUTPUT indicator should go out and the current indicator will display the set current value. By using VOLTAGE adjustment rotary switch set the required output voltage (at the same time nothing should be connected to the output terminals «+» and «-»). By using CURRENT rotary switch set the maximum allowable current value (current limit value) for your load. If in the operating mode the load resistance change will cause the excess of the specified current limit, the power supply will automatically switch to the current stabilization mode and the output voltage will proportionally fall. Connect the load to the power supply and press LOAD button. OUTPUT indicator should become red. Before you disconnect the load press LOAD button. OUTPUT indicator will go out. Before switching off the power supply, disconnect the load. Up

What instruction should I follow to work in the voltage stabilization mode?

If OUTPUT indicator is red than press LOAD button. In that case OUTPUT indicator should go out and the current indicator will display the set current value. Adjust VOLTAGE adjustment rotary switches in order to obtain the maximum allowable load voltage on the power supply output. If in the operating mode the load resistance change will cause the excess of the specified voltage limit, the power supply will automatically switch to the voltage stabilization mode with setting on terminals «+» and «-» of the preset voltage value limit, and the output current will proportionally fall. By using CURRENT rotary switch set the maximum allowable current value (current limit value) for your load. Connect the load to the power supply and press LOAD button. OUTPUT indicator should become red. Before you disconnect the load press LOAD button. OUTPUT indicator will go out. Before switching off the power supply, disconnect the load. 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. Up
