Description
The KORAD KD multi-channel series DC power supply utilizes digital encoders and button controls for simple and convenient operation, ensuring safety and reliability. It features series and parallel output operations with triple-way adjustable control. Specifically, CH1 and CH2 can output voltages ranging from 0 to 30V, while CH3 offers three voltage options: 2.5V, 3.3V, and 5V.
Additionally, the power supply includes an output switch and shutdown memory function. Fine and coarse adjustments can be easily made by pressing the knobs. The knobs offer two operating modes: continuous adjustment and lock adjustment, providing convenient and reliable operation. The keyboard can be locked to prevent improper use.
In terms of interfaces, the product is equipped with LAN, USB, and RS232, accompanied by a comprehensive set of SCPI instructions. This feature-rich interface facilitates quick setup of the test system for engineers, and it includes Labview drivers and programming examples for added convenience.
