SINGLE OUTPUT DC BENDH REGULATED POWER SUPPLY APS-3103 / APS-3320 / APS-3606
Your new DC Regulated Power Supply provides accurate stable DC power. It is ideal for test benches,
laboratories, schools and repair facilities. The multi-turn volt- age control knob helps the user accurately
dial in precise voltage. It is easy to read digital outputs (voltage & current) through a large display
accurately. This product is expertly manufactured by AKTAKOM. It incorporates SMT PC boards and a
cooling fan for reliable performance.

Operating Instructions:
1. Press the power on/off button to turn power on.
2. Adjust the voltage knob to set the desired voltage. (Voltage level is shown on the digital display)
3. Adjust the current level pot with a small regular screwdriver to set the (maxi-mum) desired
current level. (The current of the power supply is set to be the maximum at the factory)
4. Connecting a load to the output terminals and pressing the output switch will illuminate the
output indicator light and the current output can be read on the digital display.
5. The sampling terminals are not often used. Use them 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.
