Features: The MDL150 offer three sophisticated operate modes: Constant Current Mode, Constant Power Modes, and Constant Resistance Mode, enabling precise control and customization for various testing scenarios. The ability to set and adjust parameters like overvoltage, overcurrent, and overpowers protecting value ensures customs operate within specified limits. With a maximums load voltages of 150V, load current of 20A, and load power of 150W (60W over 120V), providing highly accurate measurements. The color screen offer clear visualization of data and settings, complemented by intuitively controls for brightness adjustment, screen sleep settings, and language switching between English and Chinese. Comprehensive safety designs supports setting overvoltage, overcurrent, overpowers, and overtemperature protecting thresholds. The adjustable low voltages limit value and discharge time limit value add additional safety, ensuring the device operates within safe boundaries.
