OPERATION

Switching the Power Supply On or Off

1. Connect the included power cord to the back of the device [16] and plug the other end into a suitable, earthed power socket. Always connect the device to an earthed power socket.
2. Press the Power button [1] to switch the power supply on. At this moment, there is no output voltage or current on the output terminals.
3. Press the Power button [1] to switch the power supply off.

Using the Power Supply in Constant Voltage Mode If you want to use the power supply in constant voltage mode, you set up the desired output voltage between 0V and 30V. You also set up the desired current limit. If the output current exceeds the limit, the power supply automatically goes into constant current mode.

Using the Power Supply in Constant Current Mode If you want to use the power supply in constant current mode: you set up the desired output current between 0A and 3A/5A. You also set up the desired voltage limit. Setting

Voltage and Current You can save 3 different voltage/current settings using the memory keys M1~M3.

1. Press the Voltage/Current key [5] to set the voltage. The voltage readout flashes. o For use in constant voltage mode: this is the desired constant voltage.
2. Turn the adjustment knob [11] until you reach approximately the desired voltage. Press [11] to select a digit in the voltage readout [9] and turn the adjustment knob to fine-tune.
3. Press the Voltage/Current key [5] again to set the current. The current readout flashes.
   • For use in constant voltage mode: this is the desired current limit.
   • For use in constant current mode: this is the desired constant current.
   • If you enable overcurrent protection, the output switches off automatically if the current exceeds this value.
4. Turn the adjustment knob [11] until you reach approximately the desired current. Press [11] to select a digit in the current readout [10] and turn the adjustment knob to fine-tune.
5. Press the memory key [3] again (or wait until the display to start flashing). Then press the m1-m3 button The settings are saved in the selected memory.( the display stops flashing)

Recalling Settings To recall one of the saved settings, press the corresponding memory key M1~M3 [4]. the corresponding voltage/current settings appear on the display. Note: the output is switched off automatically when you press a memory key to recall a setup.

Using Memory 3 To use memory 3, proceed as follows:

1. Set the voltage and current as desired Press memory key [3],Wait until the display start to flashing. Then Press key [4] the settings are automatically stored in memory, and until the display stops to flashing.
2. To recall the settings, press key 4.

Connecting a Load

1. Connect the load’s positive terminal to the red + terminal [14] of the power supply.
2. Connect the load’s negative terminal to the black – terminal [12] of the power supply.
3. You can connect the + or – terminal to the green earth terminal [13] of the power supply to pin the voltage to 0V (earth potential) at that terminal.
   If you leave the earth terminal unconnected, the output floats with respect to the ground.

Applying Voltage to the Load

1. Press the Off/On key [1] to apply the voltage to the load. The OUT [2] and C.V. indicators [8] light. The power supply works in constant voltage (CV) mode; the display now shows the actual output voltage and current. If the current exceeds the set current limit, the power supply automatically goes into constant current (CC) mode. The C.V. indicator goes out and the C.C. indicator [7] lights.
2. Press the Off/On key [1] to switch the output off.

PROTECTION Using Overcurrent Protection

1. To protect against overcurrent, set up the maximum current and then press the OCP button.
2. Press Off/On to apply the output to the load. If the output current becomes higher than the set value, the power supply cuts off the output and the OCP indicator flashes.
3. Disconnect the load. To recover, press the OCP key.

After the installation process is completed there will be a program group created with shortcuts for the program and for its Help. You may start them using “Start” menu. Before using the device it’s necessary to install a USB interface driver. All necessary files will be put into the program working folder, System subfolder, at the software installation. Silicon Labs Virtual COM Port (VCP) Universal Driver
   The virtual COM port driver is installed automatically when you install the application, but you can also install it manually later.

All necessary files are located in the program working directory, for example:
C:\Program Files\AKTAKOM\AKTAKOM Power Manager Express\Driver

INSTALLATION

Prompted install ### If Windows prompts you to install a driver for a

CP210x device (for example, if you plug a CP210x into your computer):

1. Use the dialog to browse for the driver location
2. Locate the driver folder (that you previously unzipped)
3. Follow the instructions ### Manual install 1. Using Windows File Explorer, locate the driver folder (that you previously unzipped)
4. Right click on the silabser.inf file and select Install 3. Follow the instructions
5. Checking device readiness If you correctly installed the hardware and software components of the system, when you start the program, it will detect the operating device itself and inform you about t successful connection. Otherwise, the program will report that the device cannot be found and will work offline. This may be due to the fact that you have not connected the device to the computer port correctly or have not installed the necessary drivers, as described in the sections above.
