ntroduction to the K6206-V20
The K6206-V20 High-Precision Dual-Channel Programmable DC Power Supply, developed by WELZEK, represents a breakthrough in DC power technology, combining high, compact design, and intelligent control. Designed for testing various electronic products, it addresses the growing demand for precise power consumption measurement in industries like consumer electronics, automotive, and IoT. With a volume and weight significantly smaller than similar imported products, the K6206-V20 offers portability without compromising performance, making it a versatile tool for laboratories and production lines.
Core Technological Innovations
The K6206-V20 integrates several key advancements:
Dual-Channel Flexibility: Each channel supports 0–20V voltage and 0–5A current, with a maximum power of 100W per channel. When both channels are used, the total power reaches 130W, allowing parallel or series configurations for diverse testing scenarios. This flexibility enables simulations of complex power conditions, such as battery charging cycles or multi-voltage system validations.
Microampere-Level Precision: The power supply achieves exceptional current measurement accuracy, with resolutions down to 100nA (on the 20mA range) and voltage resolution of 1mV. This µ capability is critical for testing low-power devices like wearables, sensors, and IoT modules, where minor power fluctuations can impact performance.
Ethernet Remote Control: Equipped with dual LAN ports (10/100 Ethernet) and USB interfaces (Type A and Type E), the K6206-V20 supports remote operation via network commands. This facilitates automated testing systems, enabling unattended long-term reliability checks or integration into existing production workflows.
Variable Output Impedance: A unique feature allows adjustable output impedance (0–10Ω with 0.001Ω resolution), mimicking real-world source behaviors for accurate load regulation tests. This is particularly useful for validating power adapters or battery-powered devices under dynamic conditions.
