Korad KA3005DS — modern programmable laboratory power supply with precise digital control and stabilized output parameters. The device provides smooth voltage regulation from 0 to 30 V and current from 0 to 5 A, which makes it an ideal choice for radio amateurs, engineers, service training workshops and laboratories.
The KA3005DS model is characterized by high accuracy, low ripple and advanced functional programming. A convenient LED display allows you to simultaneously monitor voltage, current and power, and a reliable protection system guarantees safe operation with any electronic devices.
Principle of operation
The laboratory power supply Korad KA3005DS operates on the principle of a stabilized switching power supply with digital control. The input AC voltage 220 V is converted into an internal DC voltage, which undergoes a filtering and stabilization stage.
The user provides a sufficient voltage value and current limitation using the buttons and encoder. The microcontroller analyzes these parameters and controls the power elements, maintaining stable output characteristics regardless of load changes.
The power supply operates in two main modes:
- ⚡ CV (constant voltage) — voltage stabilization mode. The device maintains a set voltage, and the current varies depending on the load.
- 🔋 CC (constant current) — current stabilization mode. When the set current is exceeded, the unit automatically reduces the voltage, protecting the connected device.
In the event of a short circuit, overload, overheating, reverse polarity of the system or instantaneous protection limits or turns off the output, preventing damage to both the power supply and the connected equipment.
Main features:
- 🎛 Precise adjustment of voltage 0–30 V and current 0–5 A
